How to Know the Buildability of a Plot: Calculation, Factors and MORE

A parcel is the small part of a extensive land area. They are used for the planning and creation of neighborhoods, urbanizations, among others.

Each of them has a level of buildability established, so it is important to know how to calculate it so as not to make mistakes when carrying out a construction or work.

When you have a plot of land, the first thing to consider is the measurements and dimensions of the space in possession, since from there a permit is processed to be able to legalize this process.

Also, you must calculate the buildability of the plot. The result can vary thanks to numerous factors involved in the field.

Also, it is essential to know what type of experience It is planned to build, because this will facilitate its construction.

Once the previous requirements have been confirmed, you must formalize an application to the nearest town hall of your locality attaching the urban planning certificate of the plot.

After you have made the request, you will have at your disposal a document with all the terrain data, including the building certificate and the assigned dimensions.

How to Know the Buildability of a Plot: Calculation Example.



To calculate the buildability of a plot you must take the following tips so you can save time.

  • To locate the exact site where the plot is located.
  • Collect the data that describe the conditions of the land (humidity, height, measurements, soil class, cadastral reference, number of plants, among others).

With these data, all the necessary information to build the house is formed.

It should be noted that the calculation can be done personally, or by a specialist. Know the plot measurements it does not represent a great difficulty.



Influential factors



The first factor that influences the value of a parcel is the location in which it is located, since, urbanized land they are more suitable to build a house.

In urbanized areas, the territorial expansion, which allows building structures of greater complexity, unlike sparsely populated areas where buildings are limited by the environmental capacity.

The common urban areas are known as: «Urbanization fabric”. The term also refers to the square meters covered by the plot or buildings with great heights.

The sites that are in rural zones or far from the city, they usually have lots that cover more length in square meters.

This type of terrain has a lower percentage of buildability, due to multiple reasons that make it unstable, among them are:

  • Amount of plants and wildlife.
  • Humidity of the place.
  • Soil conditions (brittle, stable, muddy)

When knowing the conditions of a plot in meters, before requesting the building permit the town hall, you must investigate the regulations and alignments regional and municipal, which will help you fill in missing data.

The second factor is the building planning:

It is divided into several basic systems that bring order to the constructions of populated places, they are:

  • Street and building alignment: It consists in knowing the linear position that gives form to the plane of the facade of the buildings, it also expresses with precision the division between the public and private space, using the measurements of the same.

These alignments use management plans which are studied in populated areas, are made up of blocks and are kept closed with a strip that indicates its entire perimeter.

  • Buildable depth: It is the width distance of the strip of the parcel or space, which is measured from the street alignments, it can be built at a regulatory height.

This type of depth can be considered its inner courtyard, whose territory has a percentage of high building.

The depth allows the works to have access to two facades with cross ventilation, in general, each one connects the street with the patio.

Homes that are in rural areas tend to have 4 facades They follow the four cardinal points, and also do not find any problem regarding the buildable depth.

  • Regulating height: It is defined as the maximum height expressed in meters that a large-scale construction (buildings) can have.


According to the width of the street and the number of floors assigned. Thanks to the regulatory height, the heterogeneity in the cornice lines of the street sections can be maintained.

  • Setbacks: It is the minimum and maximum amount of distance that must be taken into consideration in the plots and lands, since, from there the calculations are made to establish the size and exact position when building the house.

As extra data, when you want to build a building it is necessary to leave a few meters or unbuilt margins, in order to follow national regulations and not to breach any legal action.

Although, a case may occur in which that unbuilt land is occupied by a wall that separates one building from another.

On the other hand, the national regulations describe which are the allowed distances on the facades that are near the street. In the case of rural parcels, their normal distance can be up to 6 meters away.

  • Minimum Front of Plot: It is directly related to setbacks, since it indicates the distance that occupies the limits of the terrain. In addition, it indicates the maximum perimeter of the facade that the house to be built will have.

When you want to build a house on a small lot, a number of meters is assigned for the front, taking into consideration that the space is sufficient long and wide to be able to build it.

  • Interior patios: They are related to the occupation of the land to be built and the setbacks.

As mentioned above, in order to build lower courtyards It is mandatory to comply with the regulations, and comply with all the points found in this list.

Frequent questions



This topic is a bit confusing for the first time, which causes many people to seek advice to know the building a plot. If you are one of them, reading the next listing you will be able to get rid of most of your doubts.

How can I calculate the buildability of a Plot?



Search the building regulations article 12 numeral 3 paragraphs 9. There you will know the method to calculate it.

Is buildability and land occupation the same?



They are similar but they are not the same, buildability refers to the total square meters on which a piece of land can be built.

Instead, land occupation consists of the entire percentage of solar surface that can be occupied by the work to be done.

Finally, the two are expressed in square meters in relation to the ground, however, the occupation only describes the percentage of land.

Once the answer to these questions is known, you can start formalize your procedure When you want it, if you are well informed you will be able to carry it out successfully.

What is the Buildability of a Plot?



It is important to know this term, otherwise you will not be able to calculate the building of a house you want to build.

So, the buildability of a plot, in short, is the percentage of square meters allocated to a total area to be modified.

Thanks to this, it is possible to calculate in what conditions a land is found to later make a construction.
