San Martín de Valvení

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 2017. 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 San Martín de Valvení. That is not proof there is no water: ask local drillers.

Ground: 32% low permeability, local groundwater only; 31% karstic or fissured aquifer, medium productivity; 22% practically impermeable; 15% porous aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
