Useful and construction square meters, are they the same?

Posted by:

The square meters (along with more specific characteristics such as lighting or antiquity) are in most cases the main agent of change over the final price of a property. In general, the value of a home is marked by the size of its surface, but to avoid falling into scams or paying exorbitant amounts (no matter how inflated the market is) it is necessary to establish a fundamental difference, the one existing between the useful square meters and the construction square meters. To distinguish them at a conceptual level, one could say that the first refers to the ground you can step on and the second, to the total perimeter of the house (including partitions, walls, etc.), but we will go into the topic in greater depth.

With this simple difference between the different types of square meters that a house has, it should be enough to understand that the factor that should mark the price of a property is the usable area, and not the construction. But as the saying goes, made the norm, made the trap. There is the peculiarity that knowing exactly the useful square meters that a house owns is very difficult (especially if it is a business between individuals). To know what is the useful floor of a house without fear of being wrong, it is necessary to have its original plan, and in case of not having access to it, you would have to hire the external services of an expert on the subject such as those offered by an architect.

How to calculate the square meters?

If you want to measure the square footage of your home (whether for a future sale or rent or just to paint the walls) and save the costs of hiring an architect, there are methods that can be done by yourself, but with those that are available to be totally diligent so as not to err in the calculation.

Calculate the square meters of your home by applying an infallible formula

Knowing how to calculate the square footage of a space is not at all difficult, but you have to be careful in the execution, not using the technique commonly known as “by eye”. In order not to make any mistakes, use a measuring tape and the fundamental mathematical rules to measure the surface of a space (that is, long x wide whenever the room is rectangular or quadrangular, as in most cases). To find the exact data, do the same with partitions or construction elements that may have influence on the useful floor, and subtract what they occupy of the total surface.

The formula is simple:

useful square meters = length x width – partitions, pillars, columns, etc.

Do the calculation room by room and add up all the resulting amounts to find the useful square meters of your home. However, there are some caveats for some specific spaces in some homes, such as garages, storage rooms or terraces, places that could be called “conflict”, because of the controversy they always cause in the value of a property.

Is the space occupied by garages and terraces useful square meters?

There is a clear regulation in this regard to calculate the square meters that occupy spaces such as garages, terraces, galleries, porches, storage rooms, etc. within the total of a house. If we pay attention to the general rule, these types of enclaves that a house can have are measured in a different way, but within them, each one has its own particularity.

In particular, the terraces. The square meters of these elements can only be calculated as the other spaces if they are closed by three of its four sides. In case the terrace is only covered but not closed, the value of its surface will be 50% with respect to the floor price of the rest of the rooms.

50% is the standard measure to measure all these spaces that always generate some conflict. In this way, the space of storage rooms, garages, etc. (very important data, as long as they are of exclusive use) will be worth half of the rest of the rooms. An example to understand this differentiation to perfection: If the value of a house is around 1000 euros per square meter, the surface of your garage, storage room or gallery will be around € 500.

In this video you will see step by step how to calculate square meters, according to three different methods:

But to avoid any kind of problems or misunderstandings with customers, the simplest formula is to record in observations how the square meters of the house are distributed and indicate it explicitly in the offer. How many square meters does the interior of the building occupy and how many additional spaces? It is information that has a great value for the buyer, so if we give it to them, we will have transmitted closeness and honesty, more decisive factors in the purchase decision than a good price.
