Can you build a house on rustic land?
Asturias allows a new house on rustic land only where the town plan provides for it.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 2002. 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?

Ground: 95% practically impermeable.
Choosing where to drill takes a hydrogeologist.
