How to renovate a house in Spain?
Renovating a house in Spain can be one of the most rewarding property projects, transforming a traditional building into your dream Mediterranean home. Here is what you need to know:
Renovation costs. On the Costa Blanca, renovation costs typically range from €800 to €1,200 per m² for a comprehensive update (new kitchen, bathrooms, electrical, plumbing, flooring, decoration). A full renovation of a 120 m² house would cost approximately €96,000-144,000. For cosmetic updates only (painting, new fixtures, minor repairs), expect €300-500 per m².
Finding professionals. The Costa Blanca has a well-established network of builders, architects and project managers experienced in working with international clients. Many speak English and understand Northern European expectations for quality and finish. Getting 2-3 quotes and checking references is essential.
Permits and regulations. Minor renovations (painting, kitchen/bathroom fitting, flooring) generally do not require permits. Structural changes (removing walls, adding rooms, changing the roof) require a building licence from the local ayuntamiento. Your architect will handle the permit application process, which typically takes 1-3 months.
Timeline. A cosmetic renovation can be completed in 4-8 weeks. A comprehensive renovation typically takes 3-6 months. Major structural work with extensions may take 6-12 months. Always add a 20-30% time buffer for unexpected discoveries — older houses can reveal surprises once walls are opened up.
Adding value. Well-executed renovations on the Costa Blanca typically add 20-40% to a property's value. The most impactful improvements are: modern open-plan kitchens, updated bathrooms, new windows and doors, energy-efficient heating/cooling systems, and pool installations.
