How much will it cost to build a house in Spain in 2025?

One of the most frequent questions asked by those who dream of owning their own home is: how much does it cost to build a house? There is no single answer to this question, since it depends on many factors. For example, if you already have the land or not.

Today we give you a clear, up-to-date estimate of the real costs of building your home from scratch this 2025.

Why build your own house

Building your own home is a dream for many people, and while it involves a lot of effort, it also offers unique advantages. Here’s why it could be an excellent decision:

Total customization

Mold every inch of your home to fit your dreams and routines:

Distribution of spaces (open kitchen, office, garden, etc.).

Quality materials (floors, windows, insulation).

Architectural style (modern, rustic, minimalist).

Long-term savings

You avoid paying for unnecessary features (as in a prefabricated or second-hand house).
You can integrate efficient systems (solar panels, water recycling) to reduce future expenses.

Valuable investment

A well-built and well-designed house tends to appreciate in value over time.
If you sell it someday, you will have an attractive asset on the market.

If you have the financial means and patience, building your own house gives you freedom, quality and personal satisfaction.

Of course, do it with a good architect, a realistic budget and a clear plan. Having the advice of professionals like Taller d’Arquitectura 43720, in L’Arboç, Tarragona, allows you not only to save headaches, but also to optimize resources from the design to the end of the work.

Construction price increases

In recent years, construction costs have risen due to inflation, higher materials and labor costs. In 2025, the average price per square meter to build a house in Spain will be between €1,300 and €2,100/m², depending on the area, the type of house and the quality of the finishes.

Elements to consider in the price of building a house

Building a home from scratch involves much more than adding square footage and materials. The total cost can vary significantly depending on a number of key elements that must be considered from the beginning of the project. These include:

Topography and terrain conditions.
Size and distribution of the house.
Materials chosen and level of energy efficiency.
Location and access to the site.
Cost of the building permit (which also depends on the municipality).

These factors not only affect the overall budget, but also the feasibility, comfort and sustainability of the final result. For this reason, we recommend hire an architect in Catalonia and make a detailed planning from the beginning.

Cost of hiring an architect

An architect does not only draw plans: he accompanies you throughout the entire process, from the preparation of the basic and execution project, the construction management, to the management of the necessary licenses and permits. The cost of hiring an architect is usually between 7% and 12% of the total budget for the material execution of the work (PEM).

For example, for a house with an EMP of €200,000, the architect’s fees could range from €14,000 to €24,000. This cost may vary depending on the complexity of the project.

Steps to follow to build a house

Building a house is not only a physical work, it is also a legal, technical and economic process that must follow an order. These are the main steps:

1. Have the land: The first step is to have a buildable urban plot. If you already have it, you will save an important percentage. If not, you must also take into account the cost of the land in your budget.

2. Define the project: Together with your architect, design the house according to your needs. In this phase the style, distribution, surfaces and materials will be defined. Also, the Basic and Execution Project of the work is elaborated.

3. Requesting a building permit: Your architect will take care of this. This procedure is done at the city hall and its cost varies between 2% and 5% of the construction budget.

4. Hire a builder and quantity surveyor: A construction company is chosen to carry out the work. In addition to the architect, you will need a quantity surveyor for the direction of material execution.

5. Execution of the work: The duration of the work will depend on the complexity of the project, but in general a single-family house can take between 8 and 14 months to build.

6. Completion of work and habitability: At the end of the work, the architect will issue the certificate of completion and the certificate of habitability will be issued, which is necessary to legally reside in the house.

How much it costs to build a house with the land

If you already have the land, it is logical to ask yourself, how much does it cost to build a house with the land? Let’s see, as a reference:

Housing 100 m² basic: from 130,000 €.
Average 150 m² property: from 240.000 €.
200 m² high-end housing: from 380.000 €.

To these prices you must add:

Architect and Quantity Surveyor
Geotechnical and topographical survey
Cost of construction permit and taxes
Connections to utilities (water, electricity, sewage)
