Denia has changed. Not so long ago it was a coastal town known mainly for the ferry to Ibiza and the beaches north of Alicante. Today it is one of the most active property markets in the Valencia region, with demand for quality housing that shows no sign of slowing and a buyer profile , predominantly European, informed and well-resourced , looking for something that standard development simply cannot offer.

In that context, choosing an architect in Denia is not a minor decision. The studio you work with will determine not only how the house looks, but how long it takes to complete, how many problems arise along the way, and what it is worth when you eventually come to sell.

We have been running projects in Denia and across the Marina Alta for years. This article draws on that experience: how building and renovating here actually works, and what to consider before signing with any studio.

Why Denia is attracting increasingly ambitious architecture projects

The explanation is straightforward: Denia has something no other town of its size on the Costa Blanca can quite match. It is a genuine regional capital , with services, infrastructure, year-round life, and reliable connections to both Valencia and Alicante. At the same time, it has beaches, it has the Montgó mountain as a constant presence in the landscape, it has a historic centre with its own character, and it has residential areas like La Punta Negra, La Rota and Els Molins where the quality of what is being built is notably high.

That balance between town and nature, between local life and international appeal, is drawing a type of buyer who does not want an isolated villa in the middle of nowhere, but a well-designed home in a place with real substance. And that buyer expects architects who are equal to the project.

The market reflects this: land prices in the best areas of Denia have risen steadily, and the gap in value between a thoughtfully designed home and one built without clear criteria is becoming increasingly visible.

What sets a good architect in Denia apart from one who simply works here

There are studios with an office in Denia. And there are studios that genuinely know Denia: the planning regulations in each area, the real timescales at the local council, which materials hold up against the humidity and salt in the air, how to orientate a house to catch the levante breeze without the living room becoming uninhabitable in winter.

That difference does not show up in a portfolio. It shows up when problems arise , and in any project of real scale, problems do arise. A studio that knows the territory anticipates them. One that does not manages them as they come, usually at a cost in time and money.

What you are looking for in an architect in Denia is genuine local experience, the capacity to manage the full project , not just the design but also planning permits, contractors and site supervision , and a design sensibility that understands what the local market demands without losing the character of the project.

The areas of Denia where most building and renovation is happening right now

La Punta Negra and La Rota account for much of the demand for high-specification housing in Denia. They offer sea views, generous plots and an established setting that gives international buyers confidence. Building well here requires a clear understanding of the planning framework for low-density residential land and of how to make the most of orientation and views without compromising privacy.

Els Molins and the hillside areas at the foot of the Montgó have a different character: larger plots, more vegetation, greater natural privacy, and a visual connection to the mountain that many buyers value as highly as the sea. Projects in this area tend to have a strong landscaping component, integrating the house into the terrain rather than sitting on top of it.

Denia’s old town is also having an interesting moment, with renovations of older properties that seek to combine the character of the existing building with the performance of a contemporary home. This is technically more demanding than a new build, and one of the areas where the experience of the studio makes the most difference.

Frequently asked questions

How long does planning permission take in Denia?

For minor works and renovations that do not involve structural changes, typical timescales are between two and four months. For new builds or projects requiring a full technical submission, the process can run from six to twelve months depending on the complexity of the application and the council’s workload at the time. Working with a studio that knows the local planning authority and submits complete documentation from the outset reduces unnecessary delays considerably.

Can I build on any plot in Denia?

No. Denia’s planning framework distinguishes between consolidated urban land, developable land and protected non-developable land, with very different conditions in each category. Within urban areas, each zone has specific parameters covering site coverage, maximum height, setbacks and massing. Before purchasing a plot, it is worth having an architect review the planning conditions that apply to that specific parcel. We have seen too many cases of buyers acquiring land with expectations that the regulations simply do not allow.

Does La Quinta Fachada work across the whole area or only in Denia?

We have projects throughout the Marina Alta: Denia, Javea, Moraira, Benitachell, Teulada, Pedreguer, Ondara and other towns across the comarca. Our Javea office covers the northern part of the area, and we work regularly with Denia’s planning department. We know the local regulations, the municipal technical staff and the contractors operating in the area.

What do I need to bring to a first meeting?

Very little. The cadastral reference or address of the property is enough for us to carry out an initial assessment. If you already have title deeds, a land registry note or any existing drawings, those are helpful , they give us a clearer picture of the starting point. The first meeting requires no formal documentation. It is a conversation to understand what you want to do and to see whether it makes sense to work together.

Do you work with clients who do not speak Spanish?

Yes. A significant proportion of our clients in Denia are international buyers , German, Dutch, British, Scandinavian , who are purchasing or building here without being based in Spain. We work in English and manage the entire process from start to finish: design, planning, construction and handover. Clients do not need to understand how the Spanish planning system works or be present for every decision on site.

If you have a project in Denia, tell us about it

It does not matter where you are in the process: still looking for a plot, already have one and not sure where to begin, or sitting on a villa that needs updating. The first conversation is without obligation and tends to clarify considerably more than people expect.

Write to us at info@laquintafachada.com or call us on +34 655 00 74 09. We have offices in Javea and Gandia and are in Denia regularly.

There is a decision that many villa owners on the Costa Blanca make too late: who they ask to handle the interiors. The typical pattern is to finish the structure, resolve the basic finishes, and then — when there is already very little room to manoeuvre — start thinking about furniture and decoration.

The result, almost without exception, is a house that works but never quite comes together. The spaces do not flow as they should. The light does not fall where it ought to. The materials do not speak to one another. And by the time you reach the end of the process and want to change something, changing one thing means changing everything.

This article sets out what an interior architect actually brings to a luxury villa in Javea or Denia, when they need to be involved for their contribution to matter, and why at La Quinta Fachada we integrate interiors from the very first sketch.

Architecture and interiors: why they should not be two separate projects

The separation between architecture and interior design has an administrative logic — they are distinct disciplines with their own training and professional bodies — but in practice, in a high-specification home, that separation produces worse results than working in an integrated way.

Ceiling heights determine the scale of the furniture. The position of windows decides how light falls across materials. The thickness of the floor build-up and the routing of services define what is possible later on. These are decisions made during the architectural design phase, long before an interior designer enters the picture. If the interiors specialist arrives late, they are working within a fixed framework they had no part in creating.

When the same studio manages both disciplines from the outset, decisions are made in the right order. The architect is not designing a floor plan that the interior designer then tries to make work: both objectives are resolved together, with a shared logic and a consistent aesthetic sensibility.

In villas in Javea and Denia, where the relationship with the landscape, the quality of Mediterranean light, and the connection between inside and outside are central to the project, this kind of integration is not a refinement. It is what makes the house genuinely good.

What an interior architect brings to a luxury villa on the Costa Blanca

Defining the experience of each space before it exists

Good interior work does not begin with choosing sofas. It begins by understanding how each room will actually be lived in: what time of day the light enters, where the sea view will be seen from, whether this living room is for entertaining a crowd or reading quietly on a weeknight. That understanding is what shapes ceiling heights, the placement of lighting points, the choice of floor finish, the arrangement of furniture.

Without that conversation at the start, architectural decisions are made generically. With it, every space is designed around how it will genuinely be used.

Building a material palette that works as a system

In a luxury villa in Javea or Denia, materials are the language of the house. The local stone on the facade that continues into the living room floor. The microcement of the bathroom that picks up on the board-formed concrete of the staircase. The timber on the terrace ceiling that reappears in the interior door frames.

That kind of coherence does not happen by choosing materials separately from different suppliers. It happens when someone thinks of the house as a whole and defines a palette that holds together from first impression to last detail. It is one of the most visible contributions of integrated interior work, and one of the things that is most immediately noticeable when it is missing.

Designing lighting as part of the project, not as an installation

The lighting in a well-designed villa is not a collection of light points distributed across a services drawing. It is a design tool: it defines zones, creates depth, guides movement through the house, and extends the interior outward as evening falls.

When interiors come in late, lighting tends to default to whatever has already been roughed in. When interiors are involved from the start, lighting is designed alongside the architecture, and the difference in the finished result is striking.

Coordinating bespoke joinery and built-in elements

In high-specification villas across the Marina Alta, a significant proportion of the furniture is bespoke: kitchens, fitted wardrobes, shelving, built-in benches on terraces. That joinery needs to be specified before the plastering begins, because its dimensions determine the recesses, the heights, and the services concealed behind it.

An interior architect working from the start of the project coordinates those lead times with the construction programme, prevents last-minute adjustments on site, and ensures that the final result matches the project rather than a reasonable approximation of it.

Interiors in Javea and Denia have their own set of rules

Designing the interior of a villa on the Costa Blanca is not the same as doing so in London, Amsterdam or Munich. The climate, the light and the surroundings impose specific conditions that a good interior architect knows and works with, rather than against.

Mediterranean light is intense and direct. Materials that feel warm in northern climates can read as heavy here if they are not carefully calibrated. Colours behave differently under that sun: whites that appear cold in a showroom work beautifully in a south-facing villa. Fabrics and finishes need to hold up against the humidity and salt in the air without losing their appearance.

The connection between inside and outside is the organising principle of any project in this area. It is not simply a question of large windows. It is about floor finishes that continue seamlessly from interior to exterior, about shade landing in the right place at four in the afternoon in August, about outdoor furniture that has the same quality and coherence as the rooms it extends from.

Understanding these nuances is what distinguishes a project designed from within this context from one imported from elsewhere. At La Quinta Fachada, we have been working in this area for years, and that experience shows in the results.

Frequently asked questions

What is the difference between an interior architect and an interior decorator?

A decorator works primarily with the selection of furniture, textiles and decorative objects within a space that has already been built. An interior architect has technical training to intervene in layout, construction materials, integrated lighting and fixed elements. In luxury residential projects, the practical difference is that an interior architect can contribute from the design phase, influencing decisions that affect the build. A decorator arrives after the construction is complete.

When should the interior architect get involved in a new build project in Javea or Denia?

As early as possible — ideally from the first project meeting. The decisions that most determine the final result — ceiling heights, window placement, service routing, floor levels — are made in the first weeks of the architectural design process. If the interior architect is not at the table at that point, they are working afterwards within a framework that is already closed.

Is integrated interior architecture more expensive than hiring a decorator separately?

Not necessarily. Working with a single studio that manages both architecture and interiors removes duplication, reduces design revisions and avoids the coordination errors between separate disciplines that tend to carry a cost on site. In most projects, integration works out the same or less expensive than managing two separate teams, as well as producing a better outcome.

Does La Quinta Fachada offer interior design for renovations, not just new builds?

Yes. Many of our interior projects are renovations of existing villas in Javea, Denia, Moraira and Benitachell. The process is the same: we begin by understanding how the house is meant to be lived in, define a proposal for materials and spaces, and manage the execution from start to finish.

Do you work with clients who will not be living in the villa full time?

Yes, and it is a very common profile in this area. Many of our interior clients are second-home owners who visit the villa for several weeks a year. The aim in those cases is a house that is in good order when they arrive, easy to maintain when they are away, and finished to the standard they would expect from a property of this kind.

If you are planning a villa in Javea or Denia, let’s talk from the start

The most useful conversation about interiors is the one that happens before work begins on site, not after. If you have a project in mind — a new build, a renovation, or a villa you are looking to buy and update — we would be glad to sit down and explore how we can help.

Privacy is not achieved by closing off the home, but by designing it intelligently. From the very beginning, the project must be based on a precise reading of the site, understanding how the plot relates to its immediate context and how the space can be inhabited comfortably and discreetly.

The Surroundings as a Starting Point

Every project begins with a detailed analysis of the plot. Orientation, topography, and the relationship with neighboring properties shape the design long before the building’s form is defined. In areas with slopes or elevated views, proper site placement allows the home to open toward the landscape while remaining protected from external views.

Taking advantage of natural level changes, orienting main living spaces toward the best views, and placing the most private areas in sheltered zones is key to creating a sense of intimacy without losing spaciousness or natural light.

Designing to Look Without Being Seen

Architecture acts as a filter between interior and exterior. It is not about large, uncontrolled glass surfaces, but about deciding what is shown, from where, and in which direction. The position and proportion of openings, combined with setbacks and overhangs, make it possible to enjoy views without direct exposure.

This visual control enhances comfort and reinforces a sense of shelter, allowing the home to feel open yet protected.

The Fifth Façade and Outdoor Spaces

The roof, understood as the fifth façade, plays a key role in ensuring privacy in homes with open views. Upper terraces and rooftop spaces can become privileged outdoor areas when designed with clear architectural criteria.

Through the arrangement of volumes, the appropriate height of protective elements, and the integration of vegetation, these spaces allow enjoyment of the landscape without visual interference, naturally extending the livable area of the home.

The Landscape as an Ally of Privacy

Landscape architecture is one of the most effective tools for creating privacy without aggressive solutions. Vegetation acts as a natural filter that protects, complements, and improves the home’s integration with its surroundings.

Trees, hedges, and stepped gardens provide shade, thermal comfort, and a softer transition between public and private spaces, strengthening the relationship between architecture and landscape.

Interior Layout and Comfort

Privacy is also built from within. A well-planned layout naturally separates day and night areas, orienting shared spaces toward the views while reserving more intimate areas for protected zones.

Interior courtyards introduce natural light and ventilation without compromising privacy, creating calm and balanced environments.

A Balance Designed from the Start

Achieving maximum privacy without sacrificing views is not a one-time decision, but the result of a coherent project developed from the outset. Early architectural guidance makes it possible to anticipate urban and visual constraints, avoiding improvised solutions and ensuring long-lasting results.

When architecture adapts to both the place and the people who inhabit it, the relationship between intimacy and landscape emerges naturally.

Frequently Asked Questions

Is it possible to have open views without losing privacy?

Yes, as long as the design carefully controls orientation, height, and the position of openings to avoid direct exposure.

Can vegetation replace physical enclosures?

In many cases, yes, especially when combined with good site placement and thoughtful architectural design.

Does the fifth façade really provide privacy?

Yes, when well designed it allows for intimate outdoor spaces even in homes with elevated views.

Does the interior layout affect privacy?

Very much so. A well-organized layout is essential to protect privacy without giving up natural light.

When is it advisable to work with an architect?

From the earliest stages of the project, even before purchasing the plot, to ensure a balanced and well-considered design.

La entrada How to Achieve Maximum Privacy Without Sacrificing Views se publicó primero en La Quinta Fachada: Arquitecto en Costa Blanca, Alicante y Valencia.

These initial decisions are not a formality. They are an essential part of any well-considered residential design process. In complex and highly valuable contexts such as Jávea, where landscape, climate and planning regulations play a decisive role, understanding the place before designing is a matter of architectural responsibility.

Starting with form: a common mistake

It is very common for a project to begin with references, images or preconceived ideas about volumes and aesthetics. However, when architecture starts from form rather than analysis, conflicts quickly arise with the reality of the plot, local regulations or the actual way the house will be used.

Good architecture does not impose an idea onto a place. It interprets it. And requires pausing before drawing.

The plot is not just a datum – it is the project

A plot is more than a buildable surface. It is a set of conditions that define how a house can — and should — be built.

Orientation, topography, distant and immediate views, access points, neighbouring buildings and shadows all directly influence the layout, volume and organisation of the villa. Ignoring any of these aspects at an early stage usually leads to forced changes later, affecting both architectural quality and cost.

Understanding the plot as an active part of the project is one of the key differences between a standard villa and a truly well-designed one.

Planning regulations: the visible framework

Planning regulations should not be something checked at the end of the process. They define the framework within which the project must operate from the beginning.

Maximum heights, buildability, setbacks, permitted typologies or roof conditions all shape the design, even when they are not immediately visible. When regulations are understood early on, they become part of the design logic rather than a limitation.

This is where proper architectural guidance is essential, allowing the project to develop with clarity and coherence.

Climate and real use: designing beyond the image

Designing a villa is not only about summer living. Winter sun, wind exposure, humidity, natural ventilation and the relationship between indoor and outdoor spaces all affect comfort throughout the year.

Equally important is how the house will actually be used. A permanent home requires different decisions than a seasonal residence. Designing purely for appearance often results in houses that look good but are uncomfortable to live in long-term.

Anticipating real use is a fundamental part of responsible residential architecture.

Budget and expectations: aligning them from the start

Another common mistake is postponing discussions about budget. In reality, the order in which architectural decisions are made has a direct impact on the final cost of the villa.

Clarifying priorities, understanding what truly adds value and avoiding unnecessary complexity leads to a more coherent and efficient project. Well-designed architecture is not about adding more elements, but about making better decisions.

When early decisions are right

When these aspects are properly addressed from the outset, the project evolves naturally. Design decisions make sense, changes during development are minimal, and the final villa responds clearly to its environment, climate and users.

This is why working with an architect in Jávea from the earliest stages makes a real difference. Not only in the final design, but in the entire experience of the process. Because a well-designed villa does not begin with drawings — it begins with the right decisions.

Frequently ASked Questions

Why is it so important to make key decisions before designing a villa?

Because factors such as orientation, planning regulations, intended use and budget shape the project from the very beginning and are difficult to change later on.

When is the right time to work with an architect?

From the earliest stages, even before defining the design concept or purchasing the plot, in order to assess feasibility and avoid fundamental mistakes.

Do planning regulations limit architectural design?

No. When properly understood, planning regulations provide a framework that can be naturally integrated into the design process.

What are the benefits of working with local architects?

Local knowledge of the context, regulations and environment, which is especially important in places like Jávea.

La entrada Choosing Before Designing: The Key Decisions That Shape an Entire Villa se publicó primero en La Quinta Fachada: Arquitecto en Costa Blanca, Alicante y Valencia.

Origin and architectural concept

The traditional Mediterranean villa originates from vernacular architecture, shaped by climate, local resources and historical ways of living. Solid walls, pitched roofs, controlled openings and intermediate spaces such as porches and terraces are part of its DNA.

The modern villa, by contrast, responds to a contemporary approach: open spaces, clean geometries, a strong continuity between interior and exterior, and a more abstract architectural language. It is not just a matter of aesthetics, but a different way of understanding the home and its relationship with its surroundings.

Relationship with the environment and the landscape

One of the main debates between these two styles lies in how they integrate into the landscape.

Traditional Mediterranean architecture tends to blend in, using light colours, natural materials and a domestic scale that dialogues with the terrain. Modern architecture, on the other hand, opts for a more conceptual integration: volumes adapted to the topography, large openings towards the views and a direct relationship with the exterior.

On plots with sea views or steep slopes—common in the northern Costa Blanca—the modern approach allows for greater compositional freedom. However, when carefully designed, contemporary Mediterranean architecture can also offer highly effective solutions.

Spatial organisation and ways of living

Here we find one of the clearest differences:

Traditional Mediterranean villas

• More compartmentalised spaces
• Gradual transitions between interior and exterior
• Homes historically designed to protect from heat

Modern villas

• Open and flexible floor plans
• Large glazed surfaces
• Spaces conceived for a contemporary lifestyle, more fluid and connected

Today, however, many projects combine both approaches, adapting them to real year-round living.

Materials and construction systems

Traditional architecture typically relies on materials such as continuous render finishes, natural stone, ceramic roof tiles and more restrained joinery systems.

Modern architecture, by contrast, incorporates materials that pursue a more refined aesthetic, such as exposed concrete, large high-performance glazing systems, more complex façade solutions and technical materials focused on efficiency and durability.

The key is not the style itself, but choosing materials that respond properly to the climate, maintenance requirements and the real use of the home.

Regulations, efficiency and contemporary architecture

A less visible but fundamental aspect is current building regulations. Many “catalogue-style” Mediterranean villas do not adequately meet today’s requirements for energy efficiency, thermal comfort and solar control.

This is why so-called contemporary Mediterranean architecture emerges as a logical evolution: it maintains traditional formal references while incorporating modern criteria of sustainability, orientation and technology.

Modern or Mediterranean? The right answer

In professional practice, the real question is rarely “modern or traditional”, but rather what kind of architecture truly makes sense for a specific plot, its surroundings and the way its inhabitants live.

In places such as Jávea, many of the most successful villas are the result of hybrid solutions, where tradition and contemporary design are balanced in a natural way. That balance is, today, the true expression of architectural luxury.

Frequently Asked Questions

What is the main difference between a modern villa and a traditional Mediterranean villa?

The difference lies in the approach: modern villas prioritise open spaces and contemporary language, while Mediterranean villas are rooted in tradition and climate adaptation.

Which style works best on the northern Costa Blanca?

It depends on the plot and how the house will be used. In many cases, a hybrid solution offers the best results.

Is a modern villa less energy efficient?

Not necessarily. When well designed, it can be even more efficient than a poorly oriented traditional villa.

Is Mediterranean architecture still relevant today?

Yes, when it is interpreted through contemporary criteria rather than as a formal replica of the past.

Is it possible to combine both styles in the same house?

Not only is it possible, it is common in well-conceived projects in Mediterranean environments.

Gone are the days of thick, heavy aluminium frames that chopped up the views. At La Quinta Fachada, we work with ultra-slim or “invisible” profile systems that transform the walls of the home into pure canvases of glass.

The magic of minimalist glazing

The concept is simple but technologically advanced: “More glass, less aluminium”. Minimalist glazing allows for sliding panes of gigantic dimensions (up to 4 or 5 metres high) with joining profiles of barely 20 millimetres.

How is the disappearing frame achieved?

• Recessed frames: The perimeter frames are fully embedded into the floor, ceiling, and side walls.

• Continuous flooring: By hiding the bottom track, we ensure the living room flooring continues onto the terrace without steps or trip hazards. You only see glass.

• Fusion: When opening the window, the boundary between indoors and outdoors is completely erased, doubling the usable space of your living room.

Solar control: Light yes, heat no

A frequent doubt when installing minimalist glazing with so much glass is the “greenhouse effect”. Will the house turn into an oven in August? The answer is no, thanks to glass technology.

We do not install just any glass. We use technical glass with high solar control and low emissivity.

• Selective filter: These glasses feature invisible layers of precious metals that act as a smart filter. They let visible light (luminosity) pass through but block infrared radiation (heat).

• Result: You can have a south-facing window in the height of summer without the internal temperature soaring, reducing the need for air conditioning.

Energy efficiency and security

Minimalist glazing is not just aesthetics; it is precision engineering.

• Thermal break: Despite being thin profiles, they feature internal polyamides that prevent cold or heat from being transmitted through the metal. They are highly insulating windows.

• Security: We are talking about very thick laminated safety glass. They are practically impenetrable, acting as a transparent defensive wall.

Bearings: Moving tonnes with a finger

A window of these dimensions can weigh 500 or 600 kg. However, high-end minimalist glazing uses latest-generation stainless steel bearings that allow these gigantic panes to slide with the force of a single finger. Furthermore, for home automation lovers, these systems can be motorised to open automatically with a voice command or from a mobile phone.

If you want your house to be a viewpoint to the Mediterranean, minimalist glazing is the investment that defines the character of the home. Contact us and we will show you how to turn your walls into views.

At La Quinta Fachada, we work daily with investors and owners who ask us the same question: “If I invest €50,000 here, how much value do I add to the house?”. Well-planned architecture is a financial tool. Below, we analyse the renovations that add value and maximise ROI (Return on Investment) on the Costa Blanca.

The “open concept”: Visual square metres that sell

If there is a king among renovations that add value, it is knocking down walls. Villas built in the 80s and 90s in areas like Denia or Benissa often feature closed kitchens and dark corridors.

• The strategy: Unify the kitchen, dining, and living areas.

• The return: The international buyer (Northern European, above all) does not want isolated kitchens. Opening up the space not only modernises the home but increases the perception of square footage and light. A 60m² open-plan day area is valued much higher than three small 20m² rooms.

En-suite bathrooms: Privacy is luxury

When planning renovations that add value, the number of bathrooms matters just as much, if not more, than the number of bedrooms. The current luxury standard demands privacy.

• The strategy: Is it worth sacrificing a small box room to turn it into a second bathroom or an en-suite for the master bedroom? The answer is yes.

• The return: A 4-bedroom villa with 2 bathrooms has a much lower price ceiling than a 3-bedroom villa where each has an en-suite bathroom (3 bathrooms). In the market of Altea Hills or Cumbre del Sol, the “bath-to-bed ratio” is a key price indicator.

Energy efficiency: Invisible but vital investment

It may not be as “sexy” as a marble kitchen, but improving the thermal envelope is one of the safest renovations that add value today.

• The strategy: Replacing old joinery (windows) with thermal break systems and low-emissivity glass, and installing aerothermal systems (air source heat pumps).

• The return: Buyers are increasingly conscious of sustainability and energy costs. A villa with an A or B energy certificate sells much faster and at a better price than one with a G rating, especially to German or Scandinavian buyers who value thermal comfort over pure aesthetics.

The exterior: First impressions on the Costa Blanca

In our climate, life happens outside. Neglecting the exterior is a financial error. Renovations that add value must always look to the garden.

• The strategy: It is not just about the pool. We are talking about creating a summer kitchen, bioclimatic pergolas, or improving the façade (modernising balustrades, removing dated arches).

• The return: In Javea or Calpe, outdoor living is the main selling point. An exterior that functions as a “second living room” skyrockets the perceived value of the property.

What NOT to do (Over-personalisation)

To maximise ROI, the design must be sophisticated yet neutral. Investing in extremely personal finishes (red tiles, fixed artistic murals) usually limits the market.

Renovations that add value are those that combine functionality, light, and noble, timeless materials. If you are thinking of renovating to sell or to increase the value of your assets on the Costa Blanca, contact us. At La Quinta Fachada, we design with your well-being and your wallet in mind.

We are no longer talking about setting up a spare room at the end of the corridor. We are talking about designing an autonomous space, a “small home” within the plot that redefines the concept of luxury. At La Quinta Fachada, we propose these annexes as design jewels that allow you to share moments while maintaining the necessary intimacy for everyone.

Versatility of guest houses: Beyond sleeping

Designing guest houses offers a unique opportunity: total flexibility of use throughout the 12 months of the year. A good architectural project plans this annexe as a hybrid and multi-functional space.

• The independent suite: Its main use in high season. It must have a spacious bedroom and a full bathroom. But the detail that makes the difference is including a small coffee corner or integrated kitchenette. This gives visitors the autonomy to prepare a coffee or a light breakfast without having to enter the main kitchen of the house, gifting privacy to both parties.

• Garden office: Outside the visiting season, guest houses are the ideal refuge for remote working. Being physically separated from the main dwelling creates a psychological barrier that aids concentration and allows work life to be separated from family life.

• Wellness and leisure zone: This pavilion can easily be transformed into a private gym, a yoga studio overlooking the pool, or even an art studio, far from domestic noise.

The perfect equipment for guest houses

For these spaces to be habitable and comfortable, they cannot be treated as simple garden sheds. They require the same level of technical exigency as the main residence.

• Insulation and climate control: Guest houses must have their own independent climate control system (air conditioning and heating), separate from the central house. Furthermore, thermal insulation in roofs and walls is vital so that they are not an oven in August nor a fridge in winter.

• Total connectivity: If we want it to serve as an office or entertainment hub, the Wi-Fi signal must be impeccable. This often requires extending the data network via underground cabling from the main house.

• Acoustic comfort: Privacy is also sonic. We use high-performance glass and acoustic insulation in the partitions to ensure that what happens in the annexe, stays in the annexe.

Design and construction of guest houses

When it comes to materialising the project, there are two main aesthetic and construction approaches.

Integration vs. contrast

We can replicate the style of the main villa (tiled roofs, white walls) to provide continuity, or opt for contrast, designing a minimalist cube of glass and wood or steel. The essential factor is location: we use vegetation and changes in ground level to create visual barriers and endow guest houses with their own private terrace.

Industrialised construction

Given that we often build in established gardens where people are living, industrialised or “dry” construction is a great option. It allows the structure to be erected in a few weeks, minimising noise, dust, and rubble, affecting the owners’ day-to-day life as little as possible.

Regulations for building guest houses

This is the critical point and where professional advice is indispensable. Is it legal to build guest houses on your plot? The answer depends strictly on local urban planning regulations (General Plan of Dénia, Jávea, Altea, etc.).

As architects, we analyse the remaining buildability of the plot.

• Available metres: If the plot still has buildable square metres that haven’t been consumed, the project is viable.

• Setbacks: Distances to neighbouring boundaries must be scrupulously respected.

• Legality: A common mistake is trying to pass a guest house off as a “storage room” or “pool changing room”. To avoid fines and future problems when selling, the project must be correctly legalised as habitable surface area.

An investment that adds value
