What is the difference between useful meters and the built meters of a home?

When we consider buying a house, we put many questions on the table to find the one that meets our needs and financial possibilities.

For example, it is common to have a preference for some neighborhoods over others. It is also normal to establish priorities in terms of the number of rooms, facilities, which has a terrace, garden or garage, or which fits within our budget.

One of the factors that most influences the price of a house is its surface. This data is key to get an idea of ​​the space of a home and its potential, but, above all, of the investment that we are going to make. In fact, the price per square meter in a city or neighborhood is one of the main influencing factors when it comes to appraising a flat or a house.

However, to know the true economic value of a property, it is necessary to differentiate between its useful meters and its built meters, since both will determine its price in the market.

Difference between useful meters and built meters

The useful meters of a home encompass its entire interior surface. As it is commonly said, that surface ” that can be walked on “. This includes built-in closets and / or all those spaces that have practical utility, and excludes elements such as partitions, pillars or ventilation ducts.

On the other hand, the built meters are the total square meters that a house has. Within this measure appears the entire surface that is within the perimeter of the property. That is, it includes, in addition to the useful meters, the structure of the building (ventilation spaces, walls, drains, facilities, etc.) and the common areas (stairs, garden, swimming pool, corridors, etc.).

What does this mean? On a practical level, the meters built are data that only serves to know the value of a property, while the useful meters tell us the real space that we have.

Tips to calculate the built meters and the useful meters of a house in a simple way

If you want to sell a house, the usual thing is that you use the built area as a reference to put a price on the house. If what you want is to buy, what interests you is to know the useful meters of a house to know how much space you can take advantage of.

To avoid mismatches with both measures, the normal thing is to consult the deeds of the house, since the data of Sky Marketing includes the useful meters and the percentages corresponding to the common areas.

Precisely, common areas are one of the elements that make it difficult to calculate the useful and built square meters of a house.

As a general rule, in flats and multi-family dwellings (such as blocks of flats), the built-up area of ​​the dwelling, including the walls and half of the dividing walls (the dividing walls with other dwellings or with common areas account for half of the surface of the enclosure), is around 10% -15% higher than the useful surface.

Unclosed terraces compute 50% of their area (for example, a terrace of 10 square meters will appear as an area of ​​5 useful / built meters), while attics are considered a built area only in spaces with a height greater than 1.50 meters.

The normal thing is to indicate the square meters that correspond to the house on the one hand and, on the other hand, those of the terrace or patio. Although if these are closed by four walls, they compute 100% as useful meters and could be expressed together. The meters corresponding to the garage always count separately.

In chalets or single-family houses, the measure is the same, although in urbanizations with common garages, the part corresponding to the common built meters must be added. Regarding areas such as porches, they are computed as a constructed area and account for 50% of their total area, although only if the eaves have a flight greater than 50 centimeters.

When calculating the useful meters of a home, the private use of the common areas established in the Horizontal Property Law must also be taken into account.

An example: the first floors and the attics are assigned the exclusive use of interior patios or terraces. This means that these meters are computed for legal purposes as common areas, but are used exclusively by a home, which has the right of usufruct over them.

For this reason, this type of housing (both the penthouses with a terrace and the first floors with a patio) have a higher market price.

Is it possible to calculate the useful meters from the built meters?

Calculating the useful meters of a home from its built meters is not easy. In a generic way, a coefficient of 1.20 is taken. In other words, the meters built correspond to just over 10% of the useful meters of the home.

However, this data is relative, since in community buildings and urbanizations establishing the calculation is different because it includes many corridors and common areas.

In any case, if you want to measure your home to put it up for sale or if you want to know how tall a house is to make an offer according to its surface, our advice is that you consult, taking into account everything that we have explained in this Article.

You can also do the measurement yourself, although we advise you to be advised by an architect or to hire the services of professionals like ours. At Tajarat properties we are a leading online real estate agency in the sector and we will advise you throughout the purchase and sale process, including the appraisal of your future home.

One last note …

As you already know, some sellers “inflate” the square footage of their home to try to get a better price or add 15% directly to the useful meters to “calculate” the floor area.

However, this is a mistake and can lead to problems. If you want to sell your house, what you should do to find out how tall it is:

  • Consult the simple note of the property, which you can request at the Property Registry.
  • Check on the website or on your IBI receipt.
  • Hire a professional.

If what you want to buy is a house and its surface is important to know if its price is fair, we advise you to positively value the house based on the useful meters. It is also recommended that, before making an offer, you take into account the meters of the storage rooms and garages, since they do not usually appear on the surface of the house.

As you can see, whether you want to buy or sell a house, it is important that you know the difference between useful meters and built meters, two pieces of information that can condition a sale and purchase operation.
