Building a House on Costa Brava: Complete Guide for Homeowners & Investors

Building a house on Costa Brava is a major investment and a lifestyle decision. The region attracts homeowners from the UK, France, Germany, and across Europe thanks to its Mediterranean climate, coastal views, and strong property value retention. However, construction here requires careful planning, local knowledge, and technical expertise.

Understanding Urban Planning Rules on Costa Brava

Each municipality — including Begur, Palafrugell, Roses, Platja d’Aro, and Cadaqués — has its own urban planning regulations (POUM). These rules define:

  • maximum buildable area,
  • height restrictions,
  • distance from plot boundaries,
  • environmental and coastal protection zones.

Failing to follow these regulations can lead to project delays or fines.

Terrain, Soil & Structural Engineering

Many plots on Costa Brava are located on slopes or rocky terrain. This requires:

  • geotechnical studies,
  • reinforced foundations,
  • retaining walls,
  • advanced drainage systems.

Sea proximity also means higher humidity and salt exposure, making waterproofing essential. 

Climate-Optimized Construction

A well-built Costa Brava home should include:

  • thermal insulation for summer heat,
  • moisture protection,
  • energy-efficient heating and cooling systems.

Why Work With a Local Construction Company

A local team understands:

  • municipal approval processes,
  • regional climate challenges,
  • local suppliers and materials.
