Puentes Viejas

Can you build a house on rustic land?

The Madrid region allows no new houses on rustic land. Restoring an existing or listed building is the way.

Ley 9/2001, art. 29. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 1978. 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 2 wells and boreholes in Puentes Viejas. Half of the 2 with a depth found water at 3–7 m.

Ground: 88% practically impermeable; 6.3% surface water body.

Choosing where to drill takes a hydrogeologist.
