Navas de San Antonio

Can you build a house on rustic land?

Castilla y León allows a new house on rustic land only when a farm needs it. Otherwise it has to go in a village, or restore a building.

Ley 5/1999, art. 23.1.e. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 2004. 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 Navas de San Antonio. That is not proof there is no water: ask local drillers.

Ground: 80% practically impermeable; 12% porous aquifer, high productivity; 6.6% porous aquifer, medium productivity.

Choosing where to drill takes a hydrogeologist.
