At Fran Cortés Arquitectos we have spent years accompanying families who want to take the step of building their own home. And if there is one question we constantly receive, it is this: how much does it cost to build a house in Spain?
The reality is that there is no single figure, but we can give you reliable ranges, explain where the budget is going and help you understand how much your project can cost depending on the type of home and square footage.
Building a single-family home, whether traditional or precast concrete, is an exciting decision, and as an architectural firm specializing in single-family home designwe want to guide you from minute one.
Estimated price of building a house in Spain: general costs
Generally speaking, in Spain, the cost of building a modern single-family house is usually between 1,200 and 1,900 €/m² for average qualities and a complete project (architecture + work + management + fees).
Why this price difference?
Because variables such as:
- Design complexity.
- Construction systems (traditional, industrialized, concrete, prefabricated…).
- Energy efficiency and insulation.
- Level of interior finishes.
- Location and accessibility of the land.
- Urban planning requirements of each municipality.
In our architectural firm we always work with transparent and detailed budgets, analyzing each point to avoid surprises during the work.
What influences the final price of a single-family home?
- Topography of the terrain.
- Architectural design: the more complex, the higher the cost.
- The construction system:
- Traditional: slower, more customizable.
- Precast concrete houses: faster, more cost control.
- Materials and finishes: basic, medium or premium.
- Energy efficiency: aerothermics, SATE, high-end carpentry…
- Size of the house: the m² is usually cheaper the larger the house is.
