Retamal de Llerena

Can you build a house on rustic land?

Extremadura requires at least 1.5 ha for a new house on rustic land.

Ley 11/2018, art. 70. A town plan can be stricter.

Plan in force: Delimitación de Suelo Urbano (only marks the town's edge), from 1987. 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 3 wells and boreholes in Retamal de Llerena. Half of the 3 with a depth found water at 35–50 m.

Ground: 50% practically impermeable; 26% low permeability, local groundwater only; 24% porous aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
