About new builds in Cartagena

Cartagena is one of the most popular destinations on the Costa Blanca for international buyers. Brand-new construction here means full A-rated energy efficiency, modern open-plan layouts, private pools or shared communal areas, and the protection of Spain's 10-year structural warranty (LOE) on every developer-delivered home.

Most buyers in Cartagena come from the United Kingdom, Ireland, the Netherlands, Belgium, Germany, France and the Nordic countries. The combination of 300+ days of sun, walkable resort towns, lower cost of living than Northern Europe and direct flights from major UK and Irish airports keeps demand consistent year after year.
