luxury apartments / penthouses with terrace for sale Donostia-San Sebastian, Spain

An exclusive, spacious home in Ondarreta with stunning sea views and large terraces. Urbanización Erregenea, a privileged setting surrounded by nature and tranquillity, with communal swimming pools. Right next to Ondarreta beach. A fully exterior-facing home with two large sea-view terraces and a balcony. In need of renovation, and segregable (can be divided into two separate homes). We have included with this listing plans of the current layout as well as a proposed segregation plan. Area: 235 m² built / 211.62 m² usable. Fully exterior-facing. The price includes a parking space and a storage room. Communal motorbike parking. A development with a concierge. Ondarreta is San Sebastián's most exclusive residential beach neighbourhood, backing directly onto the sand and offering some of the finest sea views available anywhere in the city. The Erregenea development is particularly prized for its combination of resort-style amenities — communal swimming pools, concierge service, secure motorbike parking — with genuine residential privacy, all a short walk from the beach and Miramar Palace. Because the home is both in need of renovation and legally segregable, it represents a rare double opportunity: a buyer can either create one spectacular sea-view family home from the existing 235 m², or split it into two independent units, using the current-state and proposed segregation plans already provided. An outstanding project for buyers or investors who want a blank canvas in one of the most desirable beachfront settings in Spain, with the flexibility to design the outcome that best suits their needs. The two large sea-facing terraces are a particular highlight, offering the kind of outdoor living space that is exceptionally rare so close to the water in San Sebastián. With both a renovation and a segregation plan already prepared, much of the groundwork has been done, letting a buyer move straight from purchase to project without months of preliminary planning. A genuinely unique proposition on the San Sebastián market.
