The Baix Empordà property market — the heart of the Costa Brava — has a large stock of older buildings: village houses, traditional stone farmhouses (masias), coastal homes from the 1960s and 70s and properties in historic town centres. Many come to market at lower prices precisely because they need work.
For international buyers, this creates a genuine opportunity: purchase a characterful property at a competitive price, invest in renovation and end up with a home that combines local character with modern comfort. For many buyers, renovation is part of the plan from the beginning, not an afterthought.
The challenge is not the renovation itself. It is managing an unfamiliar process, with local professionals working in a different language, from a different country, often under time pressure.
The combination of lower purchase price, strong renovation potential and the possibility of creating something personal in a characterful setting is compelling — particularly in inland villages and older coastal towns where turnkey properties are rare and expensive.
Understanding the realistic cost, timeline and management requirements before committing to a purchase is the single most important thing a buyer with renovation plans can do.
Carries out the physical work. The quality, reliability and communication style of the contractor determines more about the outcome than any other single factor.
Required for projects involving structural changes, extensions or facade modifications. Prepares technical drawings and applies for major permits. Does not typically oversee day-to-day site management.
Oversees the construction process and certifies that work meets specifications. Required on most projects of any significant scope.
Electricians, plumbers, tilers, carpenters, painters. Often subcontracted through the main contractor.
For international owners who are not on site day-to-day, the challenge is not finding good professionals — it is making sure they all work together towards the same outcome, on the same timeline and within the agreed budget. Nobody does that coordination automatically.
For cosmetic and non-structural work: painting, tiling, replacing fixtures, minor bathroom or kitchen updates.
For structural changes, extensions, facade modifications and changes to the building's layout. Requires architect-prepared drawings.
Older properties sometimes also need an updated cédula de habitabilidad and a new energy performance certificate after a substantial renovation.
Many properties in Baix Empordà have heritage status that restricts modifications. Always verify permit requirements before purchasing — not afterwards.
| Scope | Typical cost per m² |
|---|---|
| Light cosmetic (paint, floors, fixtures) | 300 to 600 euros |
| Full interior (kitchen, bathrooms, floors, electrical, plumbing) | 800 to 1,500 euros |
| Full structural (structural work, new roof, full systems) | 1,500 to 2,500+ euros |
Always budget 15 to 20% contingency on top of any quote. Initial quotes tend to be 15 to 30% below final project cost.
| Full interior renovation, 120 m² | Amount (€) |
|---|---|
| Interior construction | 120,000 |
| Structural works (damp, roof) | 18,000 |
| Architect and aparejador | 8,000 |
| Permits and administration | 3,000 |
| Contingency (15%) | 22,350 |
| Total | 171,350 |
| Scope | Typical duration |
|---|---|
| Light cosmetic renovation | 1 to 3 months |
| Full interior renovation | 3 to 6 months |
| Full structural renovation | 6 to 18 months |
| Projects requiring major permits | Add 3 to 6 months for approval |
The most common factors that extend timelines: permit approval, contractor availability (demand is high in Costa Brava), hidden issues discovered during works, communication breakdowns and material lead times.
Small decisions that would take five minutes in person become multi-day bottlenecks by email.
You cannot inspect work in progress. Work that does not meet specification is significantly cheaper to fix before finishes go on than after.
Most local contractors communicate in Spanish or Catalan. Important information — a structural issue, a supplier delay, a scope change — is sometimes not passed on at all.
Additional costs tend to be presented as unavoidable facts. Without someone on site reviewing and challenging claims, budgets move quietly in one direction.
A pre-purchase assessment by a local professional can prevent very expensive overcommitment. The cost of the assessment is always less than the cost of the surprise.
Initial contractor quotes are almost always lower than the final project cost. Budget at least 15 to 20% contingency on top of any quote.
Very low quotes often indicate that the contractor is cutting corners or planning to recoup the difference through change orders later.
Working without the correct permits can result in fines, mandatory restoration and serious complications when selling.
A contractor who requires more than 20 to 30% upfront is a risk. Structure payments around milestones and hold a retention until final sign-off.
Casa Connecta Projects works with international property owners to coordinate renovation projects in Baix Empordà. We do not carry out construction work. Our role is exclusively coordination and independent representation on the buyer's side.

An architect is required for structural changes, extensions, facade modifications or changes to the building's official use. For interior-only renovations, an architect is not always legally required — but a technical architect (aparejador) is often involved regardless.
Get a realistic renovation estimate, understand the permit requirements, check whether the property has heritage status that restricts modifications, and verify whether any existing works were done without permits.
