Mambrilla de Castrejón

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.

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.

Is there water?

No well or borehole is recorded in Mambrilla de Castrejón. That is not proof there is no water: ask local drillers.

Ground: 33% practically impermeable; 33% low permeability, local groundwater only; 24% karstic or fissured aquifer, medium productivity; 8.3% porous aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
