Glaze / close external terraces. This work is supposed to represent an alteration or modification of the external appearance or configuration of the building in question. As a general rule, works that alter the exterior condition of the building are not allowed.
If an owner carries out any work that affects the aesthetics of the building without the consent of his Community of Owners, he may be obliged to delete them.
To carry out the work, in theory, you must have the permission of the City Council and the unanimous approval of the neighborhood community.
In practice, many of these works (especially in coastal areas) are done without the mandatory permission of the municipalities, since they contravene municipal regulations. Given the extension of the same, the owners usually opt for their glazing, without requesting these permits.
Three cases of interest:
Enclosure / glazing of the terrace prior to the existence of the community.
This work is an acquired right and the Community must respect it.
Previous alterations and consequences for other neighbors.
The Courts have established that if other neighbors have previously altered the façade by placing enclosures or glazing on their terraces (with or without the consent of the Community of Owners), it would not be considered "alteration of the façade" if a neighbor places a new terrace enclosure.
Age and terms
The Courts have ruled that a Community of Owners may not require a neighbor to withdraw its enclosure, when for several years no action has been taken against it, since it implies a tacit acceptance of the fact.
