Castrillo de Don Juan

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 2007. 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 5 wells and boreholes in Castrillo de Don Juan. Half of the 5 with a depth found water at 3–5 m. One spring is recorded.

Ground: 75% karstic or fissured aquifer, medium productivity; 16% low permeability, local groundwater only; 7.9% porous aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
