Can you build a house on rustic land?
The Basque Country 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 2/2006, art. 28. A town plan can be stricter.
Plan in force: Normas Subsidiarias (an older, simpler plan), from 2009. 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 Asteasu. That is not proof there is no water: ask local drillers. 4 springs are recorded.
Ground: 54% low permeability, local groundwater only; 22% practically impermeable; 21% karstic or fissured aquifer, high productivity.
Choosing where to drill takes a hydrogeologist.
