In this guide, we explain step by step how to extend your home legally, what requirements you must meet, how much it might cost, and the mistakes you should avoid.

Can you extend a house in the Comunidad Valenciana?

Yes, it is possible to extend a home, but always within the limits set by urban planning regulations. The Law on Land Planning, Urbanism and Landscape (LOTUP) and local ordinances define what can be done.

There are different types of extensions:

• Interior extensions: for example, closing off a terrace to gain more usable space.

• Exterior extensions: adding new rooms, extending the ground floor into the garden, or building another storey.

• Change of use: converting a garage or storage space into a habitable room.

Regulations for extending a home in the Comunidad Valenciana

When you decide to extend your house in the Comunidad Valenciana, several planning factors come into play:

• Type of land

  • Urban land: allows extensions, provided occupation limits, setbacks, and height restrictions are respected.

  • Developable land: requires an approved partial plan and urban services.

  • Rural land: generally does not allow residential extensions, except in limited agricultural or specific cases.

• Building volume and plot coverage: each municipality sets the maximum percentage of a plot that can be built on.

• Maximum height: adding another storey is not always possible.

• Environmental and heritage protection: stricter limits apply in protected areas or near historic assets.

Licences and permits required

To extend homes in the Comunidad Valenciana, you almost always need a major works licence, which requires:

1. Technical project signed by a registered architect.

2. Approval by the Architects’ Association.

3. Payment of municipal fees and taxes, including the ICIO (Construction Tax).

4. Sectoral authorisations, if the property is close to protected land, the coast, or public roads.

Processing time depends on the municipality but usually takes 2–4 months. Starting works without a licence can result in fines or even demolition.

Approximate costs of extending a home

The cost of an extension depends on the size, materials, and complexity. As a guide:

• Technical project and site management: 7–12% of the budget.

• Municipal fees and licences: around 4% of the cost.

• Construction: €900–€1,400 per m² depending on finishes.

• Example: extending 25 m² with average finishes costs between €30,000 and €45,000, including permits and professional fees.

Practical tips before extending your home in the Comunidad Valenciana

• Always check with your town hall.

• Request a municipal planning report for your plot.

• Work with an architect from the beginning.

• Ask for several construction quotes to compare.

• Reserve at least 10% extra for unforeseen costs.

• Take the opportunity to improve energy efficiency and installations.

Common mistakes when extending homes

• Assuming an extension can be legalised afterwards.

• Starting work without a municipal licence.

• Ignoring maximum heights or required setbacks.

• Choosing a builder only for their low price, without considering experience.

Our opinion

Extending your home in the Comunidad Valenciana is an excellent opportunity to enjoy more space and increase property value. But it must be done legally, with the support of an architect and in line with current regulations.

At La Quinta Fachada Architecture, we guide our clients through the whole process: from initial planning queries to the design of the project and execution of the works. If you are considering extending your home, we can help you do it legally, safely, and with a design tailored to your needs.

In this article, we explore why a minimalist approach fits so well in coastal Mediterranean areas and what benefits it offers in terms of aesthetics, practicality, and sustainability.

What is minimalist architecture?

Minimalist architecture is based on the idea that “less is more.” It removes the unnecessary to focus on what truly matters. This is reflected in:

• Simple, geometric shapes
• Natural, unadorned materials
• Spacious and connected interiors
• Soft, neutral colour palettes
• Natural light as a central design element

Although simple, well-executed minimalist architecture conveys calm, balance, and a strong connection to the surroundings. That connection is precisely what makes it ideal for the Mediterranean.

Why minimalist architecture in the Mediterranean makes perfect sense

Minimalist architecture in the Mediterranean is especially effective for several reasons. In places like the Costa Blanca, the setting already has a strong visual presence—sea, vegetation, open skies, and intense light. Minimalism acts as a subtle frame that enhances this natural beauty without competing with it.

Additionally:

• It encourages cross-ventilation and a connection to outdoor spaces, both vital in warm climates.
• It works well with regional features like courtyards, terraces, and flat roofs.
• It reinterprets local materials such as stone or ceramic in a modern way.

The result is modern architecture that remains rooted in Mediterranean traditions.

Aesthetic benefits of minimalism in the Mediterranean

1. Timeless design

By avoiding trends and unnecessary ornamentation, minimalist homes stay relevant and elegant over time.

2. Enhanced natural surroundings

A clean design allows the landscape, garden, or Mediterranean light to take centre stage.

3. Elegant simplicity

Beauty comes from balance—proportions, materials, light, and functionality—all without excess.

Practical and sustainable advantages of minimalist architecture in the Mediterranean

1. Energy savings

Minimalist architecture in the Mediterranean typically uses passive design principles: proper orientation, solar protection, thermal insulation… This ensures comfort and reduces energy consumption.

2. Easy maintenance

With fewer decorative elements, these homes require less upkeep and day-to-day cleaning.

3. Versatile spaces

Open layouts can easily adapt to new needs over time.

How to create a warm and inviting minimalist home

Some associate minimalism with coldness, but it doesn’t have to be that way. At La Quinta Fachada, we combine minimalist architecture in the Mediterranean with features that add warmth:

• Use of natural wood and local stone
• Incorporation of soft textiles and handcrafted elements
• Warm lighting and details that cast soft shadows
• Integration of greenery through patios or garden terraces

The result is a home that feels calm but also full of character.

A coherent vision for Mediterranean living

In short, minimalist architecture in the Mediterranean is not a fleeting trend. It is a way of building that respects the place, the climate, and a relaxed, authentic lifestyle. It’s a natural evolution of traditional Mediterranean style, adapted to modern times.

At La Quinta Fachada, we believe this vision is ideal for anyone seeking a modern, light-filled, functional home that integrates perfectly with the Costa Blanca environment.

In this article, we explain how we approach this integration so that landscape and architecture work together from the very first sketch.

What does landscape integration in the Costa Blanca mean?

Landscape integration is not just about decorating with plants. It involves analysing the natural and cultural environment, understanding the climate and terrain, and designing a smooth transition between indoors and outdoors. For example:

• Respecting the original topography rather than modifying it aggressively.
• Using native species and efficient irrigation systems.
• Creating natural shade, seating areas and visual links from inside the home.

A well-designed garden can reduce indoor temperatures, improve energy efficiency and add both aesthetic and emotional value to the home.

Interior and exterior design: a single vision for successful landscape integration

At La Quinta Fachada, we approach each project as a whole. That’s why architecture, interior design and landscaping are developed in parallel from the very beginning. This method allows us to:

• Align indoor views with garden areas or key landscape elements.
• Ensure continuity of materials and colour schemes between inside and outside.
• Guarantee privacy without turning away from the landscape.

This is how we create homes that open naturally to their surroundings, without barriers or last-minute solutions.

Key elements of landscape integration in the Costa Blanca

Every location has its own rules and beauty. In the Costa Blanca, this means considering the following:

1. The climate

We take advantage of the mild weather to create porches, pergolas or shaded areas that extend the living space throughout most of the year.

2. Local vegetation

We use hardy Mediterranean plants such as lavender, rosemary, olive trees, fan palms or cypress. These species require little water and blend seamlessly with the environment.

3. The terrain

We design terraces, dry-stone walls or staircases adapted to the slope, without impositions. Respecting the land saves costs and improves landscape integration.

4. The surrounding landscape

We always try to frame the views – whether of the sea, the mountains or surrounding vegetation. A well-positioned window or a bench facing the right direction completely transforms a space.

More than gardens: outdoor living spaces in harmony with nature

We don’t just design green areas – we create livable outdoor spaces. Our aim is for you to cook, read, chat, do yoga or simply relax in them. That’s why we include:

• Comfortable, non-slip surfaces
• Built-in benches or fixed furniture
• Ambient lighting
• Water features, fire pits or wooden elements as focal points

Every detail is designed so your garden is not only beautiful but also practical and enjoyable all year round.

Why plan landscape integration from the start of the project?

If you wait until the end, the landscape will have to adapt to an already fixed building – and you’ll miss out on key opportunities like orientation, visual connections or natural gradients.

Designing the exterior from the outset allows:

• The home to be “born” already connected to its garden
• Volumes and heights to be adjusted according to vegetation and views
• Avoiding unnecessary works or extra costs from rearranging the environment

In short: what’s designed early is enjoyed for a lifetime.

At La Quinta Fachada, landscape integration in the Costa Blanca is central to our design approach

We design homes with a Mediterranean soul – and that means treating the landscape with the same care as the rest of the project. That’s why our clients enjoy homes that open naturally to the outdoors, with gardens that don’t just beautify, but form part of everyday life.

If you’re thinking of building or renovating a home in the Costa Blanca, choose a studio that sees architecture, interior design and landscaping as one.

Get in touch and let’s design a home that’s in tune with its surroundings from the very first sketch.

Architecture and interior design: two visions that should work together

Architecture defines the volume, orientation, structure, and relationship with the environment. Interior design, on the other hand, shapes the living space: layout, materials, furniture, lighting, and atmosphere.

When both disciplines work together from the start, solutions better reflect the client’s lifestyle, make better use of natural light, and harmonise exterior and interior with consistency. Thus, integrating interior design and architecture ensures the space truly adapts to those who live in it.

Benefits of integrating architecture and interior design from the start

• Layouts adapted to real life: considering functionality and use during the architectural phase avoids later changes.
• Materials and textures that work together: from flooring to furniture, everything can be designed with aesthetic unity and coherence.
• Better use of natural light: the placement of windows and openings aligns with real interior needs.
• Saves time and money: by preventing modifications or improvised solutions during the build.
• A project with soul: creates a coherent, functional, and emotionally warm atmosphere.

Keys to achieving this integration from the beginning

1. Teamwork between architect and interior designer

From the first meeting, both professionals should share information, ideas, and goals. It’s not about interfering in each other’s work, but about combining complementary perspectives. Integrating interior design and architecture requires open communication from the start.

2. Listening to the client with a global perspective

The client’s desires influence not just the exterior design or layout but also how they want to live, the feelings they seek, and the style that represents them. Integrating interior design and architecture allows these emotions to be translated into space and form.

3. Planning furniture and storage from the drawing stage

When wardrobes, shelving or living areas are considered in the architectural phase, every centimetre is optimised, walls and corners are used effectively, and makeshift furniture is avoided. This approach enhances both functionality and aesthetics.

4. Designing lighting systems with intention

Natural and artificial lighting is part of both architecture and interior design. Planning it from the beginning ensures comfort, efficiency, and the right ambience for each room’s purpose. It also avoids poorly placed fixtures or visible installations.

5. Unifying materials and colour language

Cladding, flooring, joinery, walls and textiles should be considered together. The goal isn’t to match everything, but to give the project a coherent narrative from inside out. Integrating interior design and architecture helps establish that consistent thread.

Example: integrating interior design and architecture in a Costa Blanca home

Imagine a detached house on the Costa Blanca, where the architectural design features white volumes, clean lines, and large windows.

If a Mediterranean-style interior is planned from the beginning, using natural materials, light textiles, and built-in furniture, the interior can visually and emotionally extend the outdoor landscape. Light, colour and shapes flow with coherence. This way of integrating interior design and architecture turns the house into a harmonious whole.

A home designed as a whole

Integrating interior design and architecture from the start of the project is not a trend; it’s a way of understanding the home as a unified entity. It improves not just aesthetics, but also functionality, comfort, and the space’s identity.

At La Quinta Fachada, we work with this philosophy: we design homes where interior and exterior are conceived together—with purpose, with sensitivity, and with attention to every detail. If you’re thinking of building or renovating your home, get in touch with us—we’ll help you shape a coherent project from the first sketch.

Mediterranean interior design has evolved in recent years into a style that blends tradition, contemporary design and sustainability. It’s much more than an aesthetic: it’s a way of living, of connecting with light, climate and the materials around us.

From our studio on the Costa Blanca, we interpret this language to suit each home. In this article, we highlight current Mediterranean interior design trends—practical ideas for anyone seeking calm, beautiful and functional homes.

Natural light as the main feature

One of the pillars of Mediterranean style is natural light. Priorities include:

• Generous, well-oriented windows
• Light curtains that filter without hiding
• Open spaces visually connected with the outdoors

On the Costa Blanca, where sunshine is abundant, light becomes another design material—it draws shadows, highlights textures and marks the rhythm of the day.

Warm and neutral colours

The colours dominating current Mediterranean interiors are inspired by the landscape: white lime, sandy beige, terracotta tones, olive greens and deep blues.

The trend is to work from a neutral base (off-whites, stone, natural linen) and introduce colour through ceramic details, textiles or painted woodwork.

Natural and honest materials

Forget artificial gloss or synthetic finishes. Mediterranean character is built on materials that age beautifully:

• Natural stone and lime plaster
• Warm-toned, untreated wood
• Handmade ceramics and terracotta floors
• Plant fibres: esparto, jute, rattan
• Cotton or washed linen textiles

These materials not only bring beauty, but also help regulate temperature and create a healthy atmosphere.

Functionality without excess

Contemporary Mediterranean interiors focus on serene functionality:

• Essential, carefully selected furniture
• Open, breathable spaces: less is more
• Versatile features like built-in benches, made-to-measure furniture and integrated shelving

The home adapts to everyday life without losing soul. Every piece has purpose—nothing is superfluous.

Blending interior and exterior

A key virtue of Mediterranean design is the link between interior and exterior:

• Consistent flooring inside and out
• Seamless visuals through frameless windows
• Galleries, patios and porches that extend the living area
• Plants integrated into the furniture and layout

This blend makes the most of the climate and brings the landscape into the home.

Handmade and local touches

A contemporary Mediterranean home includes pieces with history and craftsmanship:

• Handmade Valencian ceramics
• Locally woven fibre rugs
• Reclaimed or reinterpreted furniture
• Lamps made from clay or esparto grass

Craftwork adds authenticity and character—and it supports local artisans.

Architecture that breathes

Interior design goes hand in hand with coherent architecture:

• Walls that insulate and breathe (lime, clay blocks, mixed construction)
• Cross ventilation
• Natural porches and shading
• Eco-friendly insulation

These technical decisions make the home cool in summer, warm in winter and efficient year-round. Interior and architecture must go hand in hand.

FAQs about Mediterranean interior design

Can I apply this style in a partial renovation?
Yes. Choose the right materials, bring in more natural light, and remove clutter. A smart redistribution also helps.

Is this style compatible with smart technology?
Absolutely. The style is not at odds with innovation. What matters is that systems integrate without disturbing the visual harmony.

Is it more expensive than other styles?
Not necessarily. It depends more on your choice of materials than the style itself. Many features can be adapted using local solutions.

Calm living, thoughtful design

Mediterranean interior design doesn’t seek to impress—it aims to move. It’s about designing spaces that honour light, materials and daily life. That respect the environment, enhance comfort and create homes for all five senses.

At La Quinta Fachada Arquitectura, we design homes with Mediterranean soul on the Costa Blanca, tailoring each project to its people. Because a well-designed home is one you enjoy every day.

La entrada Mediterranean interior design: Light, warmth and simplicity se publicó primero en La Quinta Fachada: Arquitecto en Costa Blanca, Alicante y Valencia.

Today, with rising demand for compact homes in areas like the Costa Blanca, space optimisation has gone from a challenge to an opportunity to design better.

What is a smart layout?

A smart layout isn’t just about “fitting everything in”. It ensures every square metre serves a purpose and that the home feels comfortable and flexible. It means viewing the house as a connected whole, where spaces flow and adapt to different uses throughout the day.

In other words: it’s about living more with less—without sacrificing comfort, aesthetics or a complete domestic experience.

Key principles of a smart small-space layout

1. Open, connected spaces

In smaller homes, internal walls often disappear. We unify the kitchen, dining and living areas to create a sense of spaciousness and bring in more natural light. Visual continuity expands the perception of space, even when the actual surface area is limited.

2. Zoning without walls

We use furniture, level changes, rugs or lighting to define areas without creating physical partitions. A kitchen island can divide spaces while keeping flow. A sliding panel or open shelving can provide privacy without enclosing the room.

3. Multifunctional, custom-built furniture

Furniture must be carefully considered in small homes. We design pieces with multiple uses: sofa beds, extendable tables, storage benches or fold-down beds.

Custom-built furniture maximises every inch, fits awkward corners, and integrates storage without overcrowding the space.

4. Natural light and cross ventilation

A smart layout doesn’t just organise space—it enhances wellbeing. Prioritising natural light and cross ventilation improves air quality and comfort. Wherever possible, we orient main rooms to the south and place openings on opposite walls to move air naturally, reducing the need for mechanical systems.

Real-life cases and applied solutions

At La Quinta Fachada, we’ve developed numerous small home projects in the Comunidad Valenciana, particularly in areas like Dénia, Jávea or Altea, where land prices and building regulations limit the available floor area. Here are a few real solutions we’ve implemented:

– 40 m² home in Jávea

• Single open space with linear kitchen, bar-style dining and sofa bed.
• Compact bathroom with shower and vertical storage.
• Fold-down bed integrated into a unit with a foldable desk.

– Apartment renovation in Dénia

• Total redistribution to eliminate corridors.
• Perimetral wardrobe acting as a wall between bedroom and lounge.
• Continuous microcement flooring to create visual unity.

– Guest house in Moraira (30 m² usable space)

• Compact volume with generous ceiling height.
• Loft space used as a bedroom.
• Built-in furniture: sofa, wardrobes and kitchen aligned within the structure.

Technology and design: space-saving allies

Today’s digital tools allow us to simulate, test and refine layouts before building. From BIM software to photorealistic renders, clients can see their future home and make informed decisions.

Smart tech in small homes also allows for foldaway features, lighting that responds to use, and systems that activate only when needed—further enhancing functionality.

What about aesthetics?

Small doesn’t mean compromising on design. In fact, minimalist interiors, natural materials and soft, neutral tones enhance the feeling of space and create a serene environment.

The key is to eliminate the unnecessary, use continuous surfaces, select durable materials and keep visual clutter to a minimum.

Frequently asked questions about small-space design

Can I fit three bedrooms into less than 70 m²?
Yes—with the right layout. By using multifunctional furniture, compact circulation areas and open-plan spaces, three bedrooms can be achieved in less surface than expected.

Is it possible to add storage without making the home feel cramped?
Absolutely. We design vertical storage, drawers beneath benches, wall-integrated wardrobes and beds with built-in compartments. The goal is always functional clarity and visual flow.

Should I open the kitchen to the living room?
In most cases, yes. An open kitchen brings in more light, enhances spaciousness and encourages social interaction. If separation is needed, sliding panels or light dividers work well without fully closing the space.

What defines Mediterranean interior design in the Comunidad Valenciana?

The Mediterranean style is not a passing trend. It’s a timeless approach to domestic space, based on three essential pillars:

• Natural light: making the most of solar illumination.
• Noble materials: stone, wood, ceramics, linen…
• Functional simplicity: spacious, connected spaces designed for enjoyment.

Far from decorative excess or cold industrial styles, Mediterranean interior design embraces authenticity, sustainability, and the balance between beauty and practicality.

Lifestyle also plays a key role: unhurried, in touch with nature, with a strong emotional connection to the home as both a retreat and a social space. It’s not uncommon to find houses with spaces for large family gatherings, long lunches outdoors, and quiet corners for relaxation.

Key Mediterranean interior design trends for 2025

1. Neutral tones with earthy accents

The colour palette is still dominated by off-whites, beige, sand, and warm greys. But these are now paired with touches of terracotta, rust, olive green or indigo blue, evoking the Mediterranean landscape: clay, the sea, olive trees, sunset skies…

These colours provide calm, spaciousness and an elegant aesthetic without losing that sense of warmth. They also blend easily with natural materials, allowing furniture or decorative pieces to stand out without overwhelming the space.

2. Tactile textures: plaster, lime, linen and wood

Texture is essential. Limewash or natural microcement finishes, exposed beam ceilings, terracotta or natural stone floors, and washed linen fabrics are all on trend. It’s not just about what you see, but what you feel: walking barefoot on a warm surface, resting your hand on a wall that breathes.

These textures don’t just feel comforting — they allow the home to age gracefully. Every crack or weathered tone adds character. Time enhances the beauty of the space.

3. Open, connected and multifunctional spaces

Contemporary Mediterranean homes avoid closed-off rooms. The living area opens into the kitchen and flows onto the porch. Spaces are flexible, allowing different uses depending on the time of day or season.

Indoor-outdoor connection is also essential: large windows, sliding doors and the continuation of materials between inside and out. This fluidity encourages better ventilation, more sunlight, and a strong sense of freedom — especially in climates like the Costa Blanca.

4. Simple, handcrafted furniture

Less is more. Furniture is chosen for its form, texture and story. Solid wood pieces, natural fibres (rattan, wicker, esparto grass), and restored elements blend with subtle contemporary touches.

Local production and Valencian craftsmanship are on the rise: built-in benches, ceramic lamps, and tables with natural stone or mortex tops. This kind of furniture is not only stylish and practical — it tells stories. Each piece is unique and captures the soul of the place.

5. Integrated indoor greenery

Plants are not just accessories — they’re part of the design. Modern Mediterranean interiors feature native vegetation (miniature olive trees, cacti, lavender, rosemary…) as a structural decorative element. Some homes even include indoor patios or vertical gardens.

Greenery improves air quality, adds freshness, and turns every corner into a small oasis. It also strengthens the bond with the local landscape — key to achieving a true Mediterranean feel in harmony with its environment.

Mediterranean functionality: living well without sacrificing style

One of the strongest aspects of Mediterranean design is how beauty and practicality go hand in hand. Every trend responds to a real need:

• Large windows → more light, lower energy use.
• Natural materials → sustainability, durability, wellbeing.
• Open spaces → sociability and flexibility.
• Soft colours → visual rest and spaciousness.

Designing a Mediterranean home isn’t just about making it “pretty”. It’s about creating a space for better living — more connected to the environment and to oneself.

And in that sense, every detail matters: from furniture layout to building orientation, from plant selection to choosing Mallorcan shutters or linen blinds. Everything has a practical reason, suited to the Mediterranean climate and lifestyle.

Mediterranean interior design and architecture: a necessary dialogue

At La Quinta Fachada, we integrate interior design from the very start of the architectural project. It’s not about adding finishes at the end — we conceive the home with that Mediterranean identity from the first line on the drawing board.

Our approach includes:

• Optimal orientation to capture the sun.
• Fluid room layout.
• Material selection in harmony with the local climate and aesthetic.
• Light-touch yet impactful interventions: skylights, patios, latticework, built-in furniture…

Because true Mediterranean luxury is not about extravagance — it’s about nature, thoughtful design, and fully lived spaces.

Planning your Mediterranean dream home?

At La Quinta Fachada Arquitectura, we help make that warm, light-filled, functional home a reality. Each project is tailored to its surroundings, your real needs and the lifestyle you aspire to.

Picture yourself in a home surrounded by olive trees?
Dreaming of a flat with sea views and coastal breezes?

But did you know that many of these works require specific permits from the local council? Starting work without the proper documentation can lead to fines, work stoppages, or legal issues down the line.

At La Quinta Fachada Arquitectura, as specialists in residential projects in areas such as Dénia, Moraira, Benissa, and Ondara, we know that a successful renovation starts with solid administrative planning. That’s why we’re here to clearly explain which permits are essential for legal renovations in the Comunidad Valenciana, and how to avoid common mistakes.

Do i need a permit to renovate my home?

In most cases, yes. While small-scale works may not require permission, it is generally necessary to submit at least a prior notification or obtain a minor or major works licence, especially for renovations that affect the structure, appearance, or energy performance of the property.

In the Comunidad Valenciana, planning legislation and permit procedures are managed by each local council, but there are shared criteria. The best approach is to consult a registered architect who can guide you through the process and help you avoid any issues.

Types of permits for legal renovations on the Costa Blanca

1. Renovations that don’t require a permit (Exempt Works)

Very minor works that do not affect the structure, utilities, or shared elements (in multi-family buildings).

Common examples include:

• Painting interior walls

• Changing flooring (without altering the layout)

• Replacing taps or kitchen units

• Cladding or tiling internal walls

While these works may not require official permission, it is often advisable to inform the residents’ association if the renovation affects the use of shared spaces.

2. Prior notification of works

This is one of the most common procedures in local councils across the Costa Blanca. It applies to minor renovations that do not affect the structure, but still need to be formally registered.

It requires:

• A description of the work

• Basic documentation

• Payment of a municipal fee

Examples include:

• Bathroom or kitchen renovations (without structural changes)

• Replacing external windows or doors

• Upgrading electrical or plumbing installations

• Demolition of non-load-bearing interior walls

This is a streamlined process, and work can typically begin just a few days after submitting the request.

3. Minor works licence

This permit is required when the renovation involves alterations to façades, structural elements, communal installations, or any changes visible from the outside.

Common examples include:

• Enlarging windows or door openings

• Replacing grilles, shutters, or exterior railings

• Installing pergolas, awnings, or terrace covers

• Visible replacement of enclosures or partitions

In areas like Jávea, Dénia, or Moraira, local councils are particularly strict if the property is located in a protected zone, the old town, or in developments with specific aesthetic regulations. Consulting beforehand helps avoid unexpected setbacks.

4. Major works licence

This is essential when structural modifications are involved, additional floor area is being added, or the use of the property is being changed (for example, converting a commercial space into a dwelling).

Required in cases such as:

• Extensions to the home (e.g. adding a new floor or volume)

• Works that alter load-bearing structures

• Full renovation projects requiring technical oversight

• Change of use, horizontal division, or complete restoration

This type of licence requires a full technical project signed by a registered architect and has a longer processing time, so early planning is key.

What if my renovation is a restoration?

Good question. In many homes along the Costa Blanca, particularly in towns like Benissa, Altea, or the old town of Dénia, renovations are being carried out as restorations. And in these cases, permits are also essential, even if no extensions are involved.

What qualifies as restoration?

• Structural repair of roofs or floor slabs

• Complete renewal of utility installations

• Façade restoration

• Preservation of original features in historic homes

• Improvements in energy efficiency or accessibility

In such cases, the project must be processed as a major works licence, or as a protected intervention if the property is listed or located within a BIC (Asset of Cultural Interest) zone.

Our advice: If you’re planning to work on an old village house or a property in a sensitive area, always consult your architect first. At La Quinta Fachada, we regularly manage these types of permits and know how to handle them effectively.

What happens if i renovate without a permit?

Carrying out building work without a permit in the Comunidad Valenciana can lead to serious consequences:

• Financial penalties and additional municipal charges

• Immediate stop-work orders

• Complaints from neighbours or the residents’ association

• Inability to register the work with the Land Registry

• Complications when selling the property (it cannot be legalised)

In properties with unauthorised works, even minor unregistered renovations can block a sale. That’s why investing in a legal renovation is also an investment in peace of mind.

What are square metres?

Square metres (m²) are a unit of measurement used to calculate the surface area of a space. In architecture and interior design, this unit is crucial. One square metre represents a square that is one metre long on each side. For example, if a room is 4 metres wide and 5 metres long, its surface area will be 20 m².

Sounds simple, right? And it is. But truly understanding how square metres are applied allows you to make smart decisions when buying materials, reorganising space, or planning a refurbishment.

Square metres aren’t just used for floors—they’re also used for walls, ceilings, and even façades. You’ll find them in blueprints, legal documents, quotes, and land registry records. So knowing how to calculate them accurately gives you a real advantage.

Why is it important to know the square metres of a room?

Imagine buying paint and running out. Or hiring a flooring installer who overcharges you because you didn’t measure correctly. Knowing how to calculate the square metres of a room helps you avoid all that. It gives you control, clarity, and the ability to make informed decisions.

Here are some of the main reasons to master this calculation:

• Accurately budget for materials

• Avoid waste or unnecessary purchases

• Optimise space—especially in small renovations

• Apply for permits correctly

• Assess a property’s value in the housing market

• Comply with minimum living space regulations

Even if you’re not a professional, knowing how many square metres your room has can be useful when renting or buying a property.

Tools you need to calculate square metres

Before you start, make sure you have these basic tools:

• Tape measure (preferably long and metal)

• Notepad or phone to record measurements

• Calculator (or your phone’s calculator app)

• Laser level (optional, but useful for more precise measurements)

• Ruler or measuring tape for smaller details

You can also use mobile apps that do the calculation for you, although it’s a good idea to take a manual measurement first to get a clear sense of the space.

Step by step: How to calculate the square metres of a room

The easiest way to do this is by using the basic formula:

Area = Length × width

1. Measure the length of the room (in metres)

2. Measure the width of the room (in metres)

3. Multiply both measurements: that’s the total number of square metres

Practical example:
A room measures 4 metres in length and 3 metres in width.
4 × 3 = 12 m²

And that’s it. Easy as that. However, not all rooms are that simple…

How to calculate if the room is square or rectangular

A square or rectangular room is the easiest to work with. Just make sure to measure from opposite walls and keep the tape measure straight and taut. If you apply the formula correctly, there’s little room for error.

To check if the room is rectangular:

• Ensure the opposite walls are the same length

• Measure the diagonals—if they are equal, it’s a perfect rectangle

Rooms with irregular shapes: What to do?

Rooms often come in L-shapes, with awkward corners or protruding columns. In these cases, it’s best to break the space down into simpler shapes:

• Visually divide the floor plan into rectangles and squares

• Calculate the area of each section

• Add all the areas together to get the total

Example:
A room with a small extension measures 5 m × 3 m in one part and 2 m × 1 m in another.
Total area = (5 × 3) + (2 × 1) = 15 + 2 = 17 m²

Common mistakes when measuring a room

Avoid these errors to ensure an accurate measurement:

• Not measuring in a straight line

• Ignoring skirting boards or uneven surfaces

• Forgetting small spaces like niches or corners

• Rounding figures incorrectly

• Measuring in inches or feet without converting

Tips for more accurate measurements

• Always measure twice

• Use a long tape measure to avoid joining segments

• Measure at the widest and longest points

• Move furniture if possible

• Use a pencil to mark measurement points

Apps to easily calculate square metres

These apps can help you:

• RoomScan Pro

• MagicPlan

• Measure (by Apple)

• Google Measure (Android)

• Houzz Pro (for professionals)

Most of them allow you to take a photo or scan the room to get automatic measurements.

When is it better to hire a professional?

When:

• The room has a complex shape

• There are uneven floors or sloped ceilings

• A certified floor plan is required

• It’s for an official property valuation

• You need to apply for building permits

Calculating the square metres of a room for painting

When you’re planning to paint a room, it’s not just the floor you’re interested in. You need to know the square metres of the walls and ceiling. For this, a different type of calculation is required:

Walls:

• Measure the height and width of each wall

• Multiply height × width for each wall

• Add all the surface areas together

• Subtract the areas of doors and windows

Example:

Two walls measuring 4 m × 2.5 m → 4 × 2.5 × 2 = 20 m²
Two walls measuring 3 m × 2.5 m → 3 × 2.5 × 2 = 15 m²
Total: 35 m²

Door: 2 m²
Final result: 33 m² to paint

Ceiling:

Simply calculate length × width, just as you would for the floor.

Calculating the square metres of walls for wallpapering or cladding

This is very useful for:

• Wallpaper

• Decorative panels

• PVC or wood cladding

Step by step:

• Measure each wall (height × width)

• Add the total area

• Subtract doors and windows

And don’t forget to add an extra 10% for overlaps or mistakes!

Calculating the square metres of a room for new flooring

When installing new flooring (wood, tiles, carpet, vinyl…), knowing the exact square metres is essential to buy the right amount of material. But also:

• Add 10% extra for cuts and waste

• If there are columns or curved areas, waste may reach up to 15%

Practical example: A room of 18 m² → you should buy at least 19.8 m² of material

Calculating square metres for furniture and layout

When planning furniture placement, you need to consider the actual space it will occupy.

• Mark out the furniture dimensions with tape

• Calculate its area (length × width)

• Subtract this from the total room size to determine the free space

This is extremely helpful for 3D designs, space optimisation, and avoiding mistakes like “the sofa doesn’t fit.”

Factors that can affect the calculation

• Columns

• Mezzanines

• Stairwells

• Bay windows

• Uneven levels

All of these can alter the calculation. You’ll need to decide whether to include or exclude them depending on the purpose of the measurement.

Difference between usable and built area

This concept is important when buying or renting property.

Usable area: the space you can actually use. It does not include walls or structural elements.
Built area: includes walls, pillars, installation shafts, etc.

Example: A flat with 90 m² built may have only 72 m² of usable space.

How to record square metres in legal documents

If you need to register measurements for the land registry, notary, or property deeds, it’s essential that:

• An accredited professional (architect or technical surveyor) carries out an official measurement

• The report includes a sketch or floor plan

• The calculation follows local regulations

What if the measurements aren’t exact?

No house is perfect. There may be:

• Walls that aren’t completely straight

• Differences between floor and ceiling dimensions

• Internal columns

In these cases, it’s best to:

• Measure in several places and take an average

• Round to the nearest tenth

• Consult a professional if legal accuracy is required

How to use a floor plan to calculate square metres

If you have access to a floor plan:

• Use the graphic scale shown on the plan

• Measure with a ruler (e.g. 1 cm = 1 m)

• Apply area calculations

Floor plans allow you to take measurements even without being physically present in the space.

Converting other units to square metres

Use these conversions when working with foreign plans or furniture purchased from abroad.

Measurements during renovations: Before and after

Measure the room before starting any renovation. Once the work is complete, measure again. This allows you to:

• Compare surface area gained or lost

• Check that the builder has complied with the plans

• Update floor plans or property deeds

Recommendations for renting or selling a property

• Ensure the listing matches the actual surface area

• Specify whether the square metres are built or usable

• Include floor plans to give buyers greater confidence

Measuring outdoor spaces

If you want to measure terraces, balconies, or patios:

• Use the same formula: length × width

• Be aware of local regulations: these areas are not always counted as 100% usable

Some covered terraces may count as only 50% of usable space in certain urban areas.

FAQs on how to calculate the square metres of a room

What if the room is L-shaped?
Divide the room into two rectangles, calculate each one separately, and add them together.

Should I include the space under the bed or wardrobe?
Yes, if it’s part of the free floor area. No, if it’s a fixed or built-in structure.

Can I use my phone to measure?
Yes. There are augmented reality apps that are fairly accurate, although it’s always best to double-check with a tape measure.

Which area counts when selling my home?
The built area, although it’s advisable to also state the usable square metres.

Are walls included in the square metre calculation?
Yes, in the built area. No, in the usable area.

What margin of error is acceptable in measurements?
A 2–3% margin is acceptable for manual measurements. For official plans, professional accuracy is required.
