Building in the Costa Blanca raises many questions for those looking to construct their home in this area. From permits and land types to energy efficiency and estimated costs, it’s common to have doubts before starting. In this article, we answer the most frequent questions we receive in our studio clearly and concisely.

Building in the Costa Blanca: Can I build on any plot of land?

No. You can only build on land classified as urban or developable. The plot must have road access, connections to utilities (water, electricity, sewage), and comply with local urban planning regulations.

Permits needed to build in the Costa Blanca

You will need the following:

• Basic and execution project signed by an architect
• Geotechnical study
• Building permit from the local council
• Site management (architect and technical architect)
• Ten-year structural warranty (in many cases)
• Approval from the architects' association

How long does building in the Costa Blanca take?

From the moment you purchase the plot, the usual timelines are:

• Architectural project: between 1 and 2 months
• Building permit: 1 to 3 months (depending on the council)
• Construction: between 8 and 14 months, depending on the size and complexity of the project

Construction costs in the Costa Blanca

Costs vary, but as a general guideline:

• Project + fees + permits: between €8,000 and €15,000
• Turnkey construction: between €1,300 and €2,000/m²
• Extras (landscaping, pool, home automation...): depending on your needs

Is energy efficiency mandatory for new homes?

Yes. Current regulations require a minimum level of energy efficiency. Since 2021, all new homes must be nearly zero-energy buildings. That’s why at La Quinta Fachada we always design with sustainability in mind, integrating bioclimatic solutions and energy-saving systems.

Can I make changes during construction in the Costa Blanca?

Yes, changes are possible, but they must be approved by the technical team (architect and site manager) and reported to the council. Sometimes, it is necessary to revise the original project and obtain new approval.

Building near the sea in the Costa Blanca: Are there restrictions?

Yes, there are limitations under the Coastal Law. You cannot build within 100 metres of the shoreline. Furthermore, some plots require special authorisations if they are near protected areas or cliffs.

Is phased construction possible in the Costa Blanca?

Yes, building in phases is possible. However, it requires clear technical planning and a building permit that reflects this intention. It’s important to ensure the home can be legally inhabited at each stage.

Sustainable materials for construction in the Costa Blanca

Recommended materials for this region include:

• Local natural stone
• Certified wood
• Eco-friendly insulation (cellulose, rock wool, cork)
• Solvent-free paints
• Windows with thermal break systems

Additional expenses when building in the Costa Blanca

Other costs to consider:

• VAT or property transfer tax on the plot purchase
• Urban development fees (building permit, waste fee…)
• Professional fees
• Notary and land registry
• Utility connections
• Construction, Installation and Works Tax (ICIO)

Professionals you need to build in the Costa Blanca

To build with confidence, you need a full technical team:

• Architect
• Technical architect (site manager)
• Experienced builder
• Installation engineer (if applicable)
• Legal adviser or consultant for complex paperwork

Common mistakes when building in the Costa Blanca (and how to avoid them)

1. Buying land without checking if it’s buildable

Before purchasing a plot, request a planning certificate from the local council. Don’t rely solely on what the estate agent or seller tells you.

2. Skipping the geotechnical study

Skipping this step can be expensive. Soil conditions vary greatly across the Costa Blanca, and poor foundations can lead to serious structural issues.

3. Ignoring slopes and orientation of the land

A plot with views may have slopes that are hard to build on if not planned properly. Also, poor orientation can lead to dark or overheated homes.

4. Failing to plan utilities and construction phases

Connecting electricity, water or sewage can delay your build if not requested in time. Therefore, it’s important to plan each step from the start.

5. Not considering energy efficiency from the design phase

Using passive systems (porches, overhangs, cross-ventilation) from the start improves comfort and reduces consumption without raising c
