What factors affect the price of building a carport? with Reformia
The average cost of building a garage can be around 250 € - 300 €/m². However, this price can vary significantly depending on the material used in construction, finishes, and the type of garage in question (attached, underground, etc.). For average quality, a single-vehicle garage can cost around 9,000 €.

1. Labor
In this section, you would need to differentiate between the cost of construction itself and the fees of an architect and project manager if it is necessary to draft a project and request a permit. For a small-scale project, such as building a garage, an architect can charge on average 8% of the Material Execution Budget (PEM).

2. Garage dimensions
This is an essential factor. On one hand, because the budget is calculated based on a price per m². The larger the garage surface, the more material is needed for its execution and more working hours are required for its construction.

3. Type of garage
This decisively influences the budget in case a project is necessary. Building a carport requires a permit or a declaration of responsibility, but in the case of those with special construction difficulties, both the need to have a project and to request a permit and pay the Construction, Installations and Works Tax (ICIO), will significantly increase costs. This would be especially true for underground garages.

However, this price can vary significantly depending on the material used in construction, finishes, and the type of garage in question (attached, underground, etc.). For average quality, a single-vehicle garage can cost around 9,000 €.

For average quality, a single-vehicle garage can cost around 9,000 €.

1. Initial Site Inspection and Assessment
A qualified constructor visits your property to evaluate the terrain, soil conditions, existing utilities, and access points. This inspection determines foundation requirements, drainage needs, and any potential complications that may affect the final budget.

2. Design and Technical Plans
Based on your specifications and local building codes, an architect or engineer prepares detailed plans including dimensions, materials, and structural design. These plans are essential for obtaining building permits and providing accurate cost estimates.

3. Obtain Building Permits and Licenses
Your constructor files necessary permits with local municipal authorities (Ayuntamiento). This process typically takes 2-4 weeks and ensures the garage complies with zoning regulations, safety standards, and neighborhood requirements.

4. Foundation and Site Preparation
The construction team prepares the ground, excavates if needed, and pours the concrete foundation. This stage includes reinforcing steel placement and proper curing time, which is critical for structural integrity and long-term durability.
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.
Garage type
Attached garages are more economical (250-300 €/m²), while underground or semi-buried garages can cost significantly more due to excavation and drainage requirements. Detached garages have an intermediate cost.
Construction materials
The use of brick, reinforced concrete, or cement blocks directly affects the budget. Metal structures are generally more economical than traditional masonry construction.
Finishes and installations
Painting, tiling, polished concrete flooring, drainage systems, and thermal insulation significantly increase the final cost. A basic garage without finishes is much more economical than a fully finished one.
Number of spaces and dimensions
A single-car garage (30-35 m²) costs around 9,000 €, but a double garage (60 m²) does not double the price due to economies of scale. Special ceiling heights also influence the budget.

How much does it cost to build a garage? Prices from 3,500 € to 25,000 €
The average cost of building a garage can be around 250 € - 300 €/m². However, this price can vary significantly depending on the material used in construction, finishes, and the type of garage in question (attached, underground, etc.). For average quality, a single-vehicle garage can cost around 9,000 €.
These are garages built in single-family homes, both detached and semi-detached. Their main advantage is that they are next to the property and in many cases can be accessed directly from inside it.

For average quality, a single-vehicle garage can cost around 9,000 €.
When building an attached garage, you are increasing the useful floor area, so you will need to request a permit or submit a declaration of responsibility, depending on the regulations of each region and municipality. If it relies on the home's structure, a project may also be required. On the other hand, once the work is finished, you will need to notify the Property Registry so it can update the useful floor area data.
Regarding the materials used, it is common for these to be built-in garages using the same materials as the property to maintain aesthetic continuity.
Building an external attached built-in garage of about 25 m² finished with monocoat mortar on the outside and automatic door costs around 9,000 €. If the foundation and concrete floor are already prepared, the cost would be reduced by approximately 30%.
Garages annexed to the home
These are garages built independently of the home, with the advantage that they don't alter its aesthetics and you can opt for different finishes. Also, being separate, they are more versatile, allowing them to be used, for example, as a workshop. Another advantage is that you can save costs if you opt for building a sandwich panel or wooden garage, to name two examples.
