Gijón

Can you build a house on rustic land?

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

DL 1/2004, art. 124. A town plan can be stricter.

Plan in force: Plan General (a full town plan), from 2019. 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 163 wells and boreholes in Gijón. Half of the 140 with a depth found water at 32–140 m. 49 springs are recorded.

Ground: 30% low permeability, local groundwater only; 29% karstic or fissured aquifer, high productivity; 25% practically impermeable; 14% porous aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
