When buying or selling a property in Spain, it is essential to understand the difference between usable surface area En constructed surface area, as these terms significantly affect the property’s value and functionality.
What is usable surface area?
De usable surface area refers to the habitable space in a property, meaning the square meters you can actually use daily. This includes interior areas free of walls and structural elements, such as:
- Living rooms
- Bedrooms
- Kitchens
- Bathrooms
This measurement excludes walls, pillars, and utility conduits, though built-in wardrobes are included in the usable surface area.
What is constructed surface area?
De constructed surface area covers the total space enclosed by the property’s outer perimeter. It includes:
- External walls
- Internal walls
- Structural elements
- Terraces and balconies (counted at 50% if covered and 100% if enclosed by three sides)
This measurement is typically 15% to 25% larger than the usable surface area.
Applicable regulations in Spain
In Spain, the definitions and calculations for these surface areas are regulated by Order ECO/805/2003, which establishes the rules for real estate valuation for financial purposes.
Importance of knowing the difference
- Property Valuation: The price of a property is usually based on the constructed surface area, while the usable surface area reflects the real livable space.
- Taxes and Fees: Certain taxes, such as the Property Tax (IBI), are calculated based on the constructed surface area.
- Property Comparisons: Knowing both measurements allows you to accurately evaluate and compare different properties.
Practical considerations
- Common areas: In multi-unit buildings, the constructed surface area may include a proportional share of communal areas, such as hallways or staircases.
- Terraces and balconies: Depending on their configuration, these may be calculated differently as part of the constructed surface area.
FAQ: Usable and constructed surface area in Spain
1. What’s included in the usable surface area?
The usable surface area refers to the parts of the property that can be directly used for living. It includes:
- Bedrooms, living rooms, kitchens, and bathrooms.
- Built-in wardrobes.
- Interior spaces free of walls and structural elements.
Example:
In a 100 m² apartment, if walls and structural elements occupy 15 m², the usable surface area would be 85 m².
2. Does the usable surface area include balconies or terraces?
It depends. In most cases:
- Fully enclosed balconies are included as usable surface area.
- Open terraces or balconies are not typically included unless specified, but they may count partially under certain local regulations.
Example:
If an apartment has a 10 m² covered terrace, it might be included as 5 m² of usable area (50%), depending on regional guidelines.
3. What about common areas in an apartment building?
Common areas (staircases, lobbies, elevators, etc.) are not included in the usable surface area. However, they are accounted for in the constructed surface area, typically as a proportional percentage assigned to each unit.
Example:
An apartment measuring 120 m² of constructed area may include 10 m² of shared common spaces, leaving 110 m² as its private constructed area.
4. Why is the constructed surface area always larger?
Constructed surface area includes everything within the outer walls of the property, such as:
- Internal and external walls.
- Load-bearing elements.
- Proportional communal spaces (for apartments).
This measurement reflects the total “footprint” of the property, not just the livable space.
Example:
For a 120 m² apartment:
- Constructed area: 120 m².
- Usable area: 95 m² (after subtracting walls and other non-usable spaces).
5. Is there an official guide to measure these areas?
Yes, measurements are regulated by Order ECO/805/2003. Additionally, many municipalities follow technical building codes such as the Código Técnico de la Edificación (CTE) for consistent calculations.
6. Can two properties with the same constructed surface area have different usable areas?
Absolutely. The design and layout of a property greatly impact the usable surface area. Properties with fewer walls, efficient layouts, and minimal hallways tend to have a higher usable-to-constructed ratio.
Example:
- Property A: Constructed area of 100 m², with 85 m² usable area (efficient design).
- Property B: Constructed area of 100 m², with 75 m² usable area (many walls and corridors).
7. What should I prioritize when buying a property?
Focus on the usable surface area, as this reflects the actual living space. However, be aware of the constructed surface area for legal, tax, and valuation purposes.
Pro Tip: Always request both measurements and check the layout to ensure the property meets your needs.
