Architects & Builders in Torrevieja for Property Renovation

Many foreigners buying property in Torrevieja purchase homes that need renovation, extension, or reform. Understanding how the construction and planning system in Spain works is essential before you start.

When do you need a licensed architect?

In Spain, a licensed architect is legally required for: new construction, extensions that increase the building's footprint, changes to load-bearing structures, and projects requiring a major building licence. For smaller works (bathroom reform, kitchen refit, painting), you only need a minor works licence and a registered builder.

Never start work without the relevant licence. Unauthorised building work (obra ilegal) can result in demolition orders, significant fines, and complications when you try to sell.

How to protect yourself when hiring a builder

  • Check for tax registration: Any legitimate builder should be registered with Agencia Tributaria and issue a formal invoice with IVA. Avoid paying entirely in cash with no invoice.
  • Get a signed contract (contrato de obra): Specify scope, materials, timeline, payment schedule, and penalty clauses for delays.
  • Payment schedule: Never pay more than 30–40% upfront. Typical: 30% on signing, 30% at midpoint, 30% on completion, 10% retention for snagging.
  • Use an architect as project manager: Even when not legally required, this adds a layer of professional accountability.
  • Budget 15–20% contingency: Older Spanish properties regularly reveal hidden problems during renovation — damp, illegal wiring, structural issues.
