CASTELLDEFELS

Overlooking the Mediterranean and just moments from the beach, this renovation in Castelldefels begins with an exceptional setting. The house unfolds over two levels with a roof terrace — a seaside retreat whose full potential was already present in its structure, yet only truly revealed through the renovation.

Originally built in the 1970s as a holiday home, the property was defined by fragmented layouts and dim, compartmentalized rooms. Our intervention was based on simplification and spatial clarity. By reordering the interior, we sought to allow natural light to once again become the defining element of the house — not only on the upper floor, but throughout the more private rooms on the lower level as well. The result is an open and fluid sequence of spaces shaped by brightness, calm, and a renewed sense of amplitude.

The lower level accommodates the bedrooms, conceived as quieter and more intimate areas of the home. Above, the upper floor opens into a single generous living environment where lounge, dining, and kitchen merge into one continuous space. This level was designed as the social heart of the house: open, luminous, and equally suited to everyday life and the effortless pleasure of living by the sea.

At the centre of this space stands the iron fireplace. More than a functional object, it anchors the room, gives it identity, and acts as a sculptural core around which life on the upper floor is organised. Its dark, precise materiality creates a deliberate contrast with the warmth of the wood and the restraint of the surrounding surfaces.

The element that connects the entire renovation is the natural oak flooring. It runs through both levels and becomes the architectural constant of the project. At a central point, the floor itself rises and transforms into a staircase linking the two storeys. Crafted from the same wood as the flooring, the stair establishes an almost monolithic continuity between horizontal and vertical planes. Glass balustrades allow natural light to filter down into the lower floor, reinforcing the lightness of the intervention. On the upper level, this spatial movement culminates in the iron fireplace — a sculptural counterpoint to the warmth and continuity of the timber.

For us, Castelldefels is a project about transformation through reduction. About turning a once fragmented holiday apartment into a bright, precise, and timeless home — open to light, unified through materiality, and defined by a quiet, effortless elegance.
