Houses for sale in Barcelona and Costa Brava

 Living in a house in Barcelona or the Costa Brava is a luxury available to very few. In Barcelona Sotheby’s International Realty we have a wide portfolio of houses for sale on the outskirts of Barcelona and throughout the Costa Brava for those looking to get away from the city and lead a relaxed life in front of the sea.

The best areas for luxury homes on the outskirts of Barcelona

Barcelona’s coastline is one of the areas with the most houses for sale on the outskirts of Barcelona. In the south of the Catalan capital, on the Garraf coast, we find luxury properties in small towns such as Gavà, Castelldefels, Sitges and Vilanova i la Geltrú. Well connected to Barcelona, these towns are an unbeatable option for a relaxed life without being far from the city. 

In the north, towns such as Alella, Tiana, El Masnou, Premià de Mar and Vilassar de Mar stand out. These charming little towns, located just a few metres from the sea, are full of unique houses with private gardens offering the best views of the Barcelona coastline. As if on an eternal holiday, you can enjoy the tranquillity and good climate of the Catalan coast just a few kilometres from Barcelona.

If there is a type of property with a high demand, this are the properties with sea views. In Barcelona Sotheby’s International Realty we have access to the most exclusive houses for sale in Barcelona and Costa Brava located in the most spectacular locations to delight those in love with the sea.
