Castelldefels

Can you build a house on rustic land?

Catalonia allows no new houses on rustic land. Restoring an existing or listed building is the way.

DL 1/2010, art. 47. A town plan can be stricter.

Plan in force: Plan General (a full town plan), from 1976. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 100% of the municipality.

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

Is there water?

IGME records 8 wells and boreholes in Castelldefels. Half of the 8 with a depth found water at 45–100 m.

Ground: 38% porous aquifer, high productivity; 33% porous aquifer, medium productivity; 21% karstic or fissured aquifer, high productivity; 7.6% karstic or fissured aquifer, medium productivity.

Choosing where to drill takes a hydrogeologist.
