Sant Andreu de la Barca

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 1981. 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?

No well or borehole is recorded in Sant Andreu de la Barca. That is not proof there is no water: ask local drillers.

Ground: 55% porous aquifer, medium productivity; 21% porous aquifer, high productivity; 17% practically impermeable; 6.6% low permeability, local groundwater only.

Choosing where to drill takes a hydrogeologist.
