Important factors when building a single-family home structure with Reformia
The average cost to build a house structure is around 130 €/m². The final price will depend, basically, on the type of material used (wood can significantly raise this price) and on the conditions imposed by the land according to its characteristics.
1. Consider the local climate
The climate of the area can be an important factor when choosing the type of structure and the most suitable material for building a house. Rainfall, temperatures, solar radiation, and environmental humidity affect all elements of a building.
2. Waterproof the house structure
Humidity conditions are an important factor when designing the structure of a new building. Structural moisture, produced by capillarity, can end up putting the stability of the building at risk. And interior humidity can also generate problems.
3. Consider the building's intended use
The purpose of the building is important when choosing the structural material. In fact, the Basic Document SE establishes the basic safety requirements regarding resistance and stability that structures in new construction must meet according to the building's use. In this sense, the foreseen loads are what is taken into account, and these will be different depending on whether the use is residential, industrial, or commercial.

Process Steps
The average cost to build a house structure is around 130 €/m². The final price will depend, basically, on the type of material used (wood can significantly raise this price) and on the conditions imposed by the land according to its characteristics.
1. Site Survey and Soil Analysis
A professional engineer conducts a topographical survey and soil study to determine soil bearing capacity, drainage conditions, and foundation type requirements. This analysis is crucial for Spanish building codes (CTE) compliance and costs typically €300-€800 depending on property size.
2. Foundation Design and Permits
Based on soil analysis, a structural engineer designs the appropriate foundation system (zapatas aisladas, losa de cimentación, o pilotes) and obtains building permits from local authorities. This step ensures compliance with regional construction regulations and takes 2-4 weeks.
3. Excavation and Ground Preparation
Heavy machinery excavates to the required depth, removes unsuitable soil, and prepares the base level. Proper compaction and drainage systems are installed. Costs vary significantly based on soil conditions and depth required, typically €15-€30 per cubic meter in Spain.
4. Foundation Construction
Reinforced concrete foundations are poured according to specifications. This includes formwork installation, steel rebar placement, concrete mixing, pouring, and curing. This is the most critical phase and usually takes 3-6 weeks depending on foundation type and weather conditions.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type of structural material
The choice between reinforced concrete, steel, timber, or mixed systems significantly impacts pricing. Timber can increase costs by 40-60% compared to standard concrete due to required treatment and certifications.
Geotechnical site characteristics
Soil bearing capacity, water table level, presence of rock or clay determine the required foundation depth. Poor soil conditions can double costs when piling or specialized foundations are needed.
Architectural complexity of the structure
Properties with irregular floor plans, significant overhangs, basements, or unique structures require more complex engineering calculations and additional materials, increasing the budget by 20-35%.
Required preliminary studies and permits
Geotechnical study, technical project, structural calculations, and municipal permit management vary by location. Seismic risk or flood-prone zones require stricter regulations that increase construction costs.
How much does it cost to build a house structure?
The average cost to build a house structure is around 130 €/m². The final price will depend, basically, on the type of material used (wood can significantly raise this price) and on the conditions imposed by the land according to its characteristics.
The price of building a house structure will depend on both the square meters and the materials used as well as the architectural design. In general, the structure of a single-family home is composed of the following elements:
Procedures and licenses to build a house structure
The average cost to build a house structure is around 130 €/m². The final price will depend, basically, on the type of material used (wood can significantly raise this price) and on the conditions imposed by the land according to its characteristics.
Generately, the price of the foundation to build a 120 m² single-story house on level ground without need for formwork can be around 12,000 €; if it includes formwork the price could rise to around 14,000 €.
The construction of the structure including interior partitions and walls, facades, door and window openings, etc. can cost around 800 €/m², although the price will vary depending on each project.
- Foundation: this is the first element in the construction of a house, consisting of pouring concrete on which the house will rest and which supports all its weight.
- Pillars and load-bearing walls: these are the vertical elements that transmit loads to the foundation.
- Beam and tie-rod framework: forms the horizontal elements of the house, which transmit loads to the walls.
- Floor slabs: these are the floors of the structure, which distribute weight toward the beams, walls, and columns.
Once you have the land, the first thing to do is hire an architect and surveyor who will oversee the new construction from its layout to its execution and legalization. The architect will be responsible for drafting the basic project, which is what the City Hall will require to grant the urban planning license. This license is essential, but it should not be confused with the building permit.
Next, a geotechnical study must be carried out and the project must be approved by the architect, which must be endorsed by the corresponding Association of Architects. With this documentation, you can already request the building permit.
Once construction begins, the layout deed is signed, which is the document that certifies that the project can actually be carried out.
- Roof: elements that make up the house's roof.
- Building a reinforced concrete structure for a home with ground floor of 90 m² and second floor of 60 m²: 12,000 €.
- Foundation and structure for a 100 m² home: 30,000 €.
- Single-family home structure with basement of 180 m², ground floor and first floor of 145 m², and terrace with a room of 30 m²: 80,000 €.
