If you own a villa on the Costa del Sol that needs a full renovation — whether you bought it as an investment project, it still carries the look of the 1990s, or you simply want to bring it up to the standard of today’s luxury projects — the first question is always the same: how much is it going to cost, and who can do it well?

Price of a full villa renovation on the Costa del Sol (2026)

The cost of renovating a villa in Marbella and on the Costa del Sol varies significantly depending on the scale of the works and the level of finishes:

  • Partial renovation (bathrooms, kitchen, floors): 600-900 EUR/m²
  • Full renovation with a new layout: 900-1,500 EUR/m²
  • Luxury renovation with premium materials: 1,500-2,500 EUR/m²
  • High-end villa renovation (extension, pool and landscaping included): 2,500-4,500 EUR/m²

For a 250 m² villa undergoing a full luxury renovation, the indicative construction budget is between 375,000 EUR and 625,000 EUR, plus the architect’s fees (6-12%).

What does a full villa renovation include?

A complete villa renovation on the Costa del Sol includes: demolition and debris removal, structural reinforcement if necessary, a new interior layout, complete renewal of services (electrical, plumbing, air conditioning, home automation), exterior façade and roof, swimming pool (if there is none or if it needs renovating), garden and outdoor areas, complete kitchen and bathrooms, interior and exterior joinery, painting and finishes. The architect’s fees cover the technical design, site management, permit applications and health and safety coordination.

How long does a villa renovation take on the Costa del Sol?

A full renovation of a 200-400 m² villa in Marbella or Mijas usually takes between 10 and 20 months, including design and permits (3-6 months) and the works themselves (6-14 months). Klic Arquitectos sets the timescale in the contract and has historically stayed within 5% of it. The secret lies in detailed planning before work starts and constant coordination of the trades.
