Due Diligence

Buying Land or a Plot to Build

Not every plot lets you build what you imagine. Before buying, you must verify the planning classification and buildability.

Buying land to build carries a risk that does not exist with a flat: that you cannot build what you want. The key is the planning classification.

Types of land

Urban: suitable for building, with services; the safest.
Developable: pending development (plans, urbanisation, land cessions); more uncertainty and costs.
Non-developable / rural: with strong limitations; generally you cannot freely build housing.

What to check before buying

Buildability, uses, heights and setbacks under the municipal planning.
Pending planning charges (urbanisation, cessions) and constraints (coast, roads, heritage).
The situation in the Registry and Cadastre, and available services.

We request a planning certificate or report from the Council and run the due diligence before you sign, so you know exactly what you can build.

Frequently asked questions

We answer your questions

Can I build a house on any plot of land?

No. It depends on the planning classification: urban land is suitable, developable land needs development and rural or non-developable land has strong limitations. It must be verified before buying.

What is a plot's buildability?

It is how much and how you can build under the planning (buildable metres, uses, heights, setbacks). It is worth requesting a municipal planning report before the purchase.
