Looking for luxury apartments and flats for sale in Diagonal Mar, Barcelona, Spain? This iconic seafront district blends urban sophistication with resort-style comfort. With high-rise architecture, panoramic Mediterranean views and private amenities, Diagonal Mar is among the most sought-after residential zones in Barcelona and across Spain. Whether you want a beachfront apartment, a flat with a sea-view terrace or a high-end residence inside a gated community with a pool, Diagonal Mar delivers the best of both city and coast.
Diagonal Mar is a favourite of international buyers, digital professionals and families who want elegant coastal living with fast connections to central Barcelona. The area offers luxury apartments and flats with sea views and contemporary design, gated residences with pools, gyms, landscaped gardens and twenty-four-hour security, and immediate access to beaches, parks and the Diagonal Mar shopping centre. Transport links to the city centre and the airport are excellent, demand for premium properties is strong, and the setting works equally well for long-term living or as a second-home base in Spain.
Along the frontline beach towers — such as Illa del Llac, Illa de la Llum, the Diagonal Mar Towers and the prestigious Antares Barcelona — buyers find luxury flats with large terraces, open sea views and full-service amenities in a vertical, concierge-driven format. Around Parc de Diagonal Mar, modern developments face green space and suit families who want luxury apartments close to nature and reputable schools while staying minutes from the beach. Near the shopping centre, well-connected buildings attract buyers seeking investment flats and stable long-term rentals thanks to immediate access to services, restaurants and public transport.
Inventory includes luxury beachfront apartments with panoramic terraces, spacious modern flats with pools, gyms and concierge service, family-sized apartments with three or four bedrooms and direct sea outlooks, and high-rise penthouses finished by designers with rooftop-level views. Investors also target move-in-ready flats with strong rental potential. Prices generally begin around €600,000 and extend above €3,000,000 depending on floor height, view, building and amenity package, allowing each buyer to match the apartment or flat to lifestyle and investment goals.
We specialise in premium coastal property across Barcelona, with deep expertise in Diagonal Mar. Our model is one hundred percent buyer-side representation to protect your interests; we secure access to off-market luxury apartments and penthouses, provide legal and tax coordination for international purchases, and advise on building quality, micro-location and long-term value—backed by more than thirty years of successful acquisitions in Spain.
Explore our exclusive selection of seafront luxury flats with dramatic views, apartments in gated communities with pools and gyms, spacious family flats in modern high-rises and investment properties near the beach and amenities.

Diagonal Mar works very well for both. The area has beaches, parks, schools, a large shopping centre, restaurants and excellent transport links, so daily life is convenient and comfortable all year. At the same time, resort-style amenities and sea views make it ideal as a second-home base in Barcelona.
As a guideline, prices generally start around €600,000 for quality modern flats and can exceed €3,000,000 for larger seafront apartments, high-floor units and designer penthouses with panoramic terraces and premium amenities.
You’ll find luxury beachfront apartments with wide terraces, modern flats in gated communities with pools and gyms, family-sized apartments with three or four bedrooms and direct sea views, and high-rise penthouses with rooftop-level panoramas. Many buildings offer concierge service, private parking and landscaped communal areas.
Frontline towers such as Illa del Llac, Illa de la Llum, the Diagonal Mar Towers and Antares Barcelona are especially sought after for their sea views, amenities and security. Around Parc de Diagonal Mar, family-oriented developments offer green views and quick access to both parks and beaches.

Most premium developments in Diagonal Mar offer 24-hour security, controlled access, concierge or porter service and secure parking. Many are gated communities with monitored entrances, providing a high level of safety and peace of mind for residents and second-home owners.
Yes. Families value the combination of modern buildings, larger apartment layouts, green areas, beaches and nearby schools. Pools, play zones and car-free communal spaces inside many complexes make the area particularly attractive for younger families.
