Castillazuelo

Can you build a house on rustic land?

Aragón requires at least 1 ha for a new house on rustic land.

DL 1/2014, art. 34.2. A town plan can be stricter.

No town plan: the region's general rules apply. The region's planning viewer ↗

The SIU does not map land classes here: the town plan is the source.

Only the town hall can confirm it, in writing: ask for a certificado urbanístico.
