Basements are very common in Greek properties, but their use depends on specific regulations.
By definition, a basement is a space that is mostly below ground level, with its ceiling not exceeding a certain height above the surrounding ground. These spaces are typically used for storage, parking, or technical purposes.
However, in some cases, basements can be converted into living spaces — but only if they meet certain conditions.
These include:
If these requirements are met, a basement can be legally classified as a main-use space, such as an apartment or office.
In properties built on sloped land, basements may be partially or fully exposed, which can make them more functional and closer to ground-floor spaces.
Older properties may follow different rules, as regulations have changed over time. This is why each case needs to be evaluated individually.
In some situations, it is also possible to legalize a converted basement, especially if the change was made before certain regulatory deadlines.
Overall, basements offer flexibility and potential, but their use depends on proper planning, legal compliance, and professional guidance.
