Residence 0110 is the renovation of an elegant, exclusive apartment in Barcelona’s 22@ district.

The 22@ neighborhood in Poble Nou is an urban project that transforms 200 hectares of former industrial land into a hub of innovation.

To create a minimalist yet characterful atmosphere, the interior designer selected key pieces such as the white Arpa 18 radiator—a breath of fresh air that combines efficiency, integration, and design.

The apartment sits on a high floor of a chamfered block facing southeast, with open views stretching toward Montjuïc thanks to the nearby train tracks. The original layout featured two narrow bays, each only three meters wide, divided into a sequence of small rooms that no longer matched modern living needs.

The new plan is built around a perfect square, 6.15 m per side, paired with a right triangle that marks the transition. The square is the heart of the home: it brings together the kitchen, living, and dining areas, while leaving space for a library, reading nook, play zone, and the overall social core of the residence.

This geometry was made possible by demolishing structural walls and reinforcing the building, leaving one remnant of the old system—a central pillar required both for stability and spatial clarity. Clad in brass, this subtle divider separates the kitchen/dining area from the rest of the space, hinting at different uses without closing them off. Next to the square lies the triangle. With no physical boundary but a lower ceiling marking the shift, it serves as the circulation area leading to the two bedrooms (one en suite) and a second bathroom.

With such a simple layout, materials take center stage in shaping the atmosphere. A continuous strip of open-pore black-stained oak runs along several walls, into the triangle, and across the base of the kitchen. It unifies distinct functions with a single texture. Stainless steel doors blend flush with the wood and also define the upper kitchen cabinetry. Most of the central space is white, except for the library wall, which reveals a pale pink backdrop. That same shade appears on the floor and ceiling of the triangular zone. The brass-clad pillar, stopping at the height of the lower ceiling, reinforces its dual role as structural support and spatial anchor.

The bedrooms are reached through the flush stainless steel doors, leading into spaces defined by white walls and natural oak floors. Bathrooms highlight a play of textures: gray microcement walls, pale pink accents, and striking Macondo black marble.

Conceptually, the triangle is the generator of the plan. It defines the rotation of the layout, and its diagonal logic reappears throughout: the brass-clad pillar is trapezoidal with one slanted side, custom brass furniture echoes triangular motifs, and the en-suite bathroom door—made of brushed stainless steel—is split diagonally to create privacy. Even the 60x60 floor tiles are arranged to solve the 615 cm span with a diagonal rhythm of 15 cm inserts.

Much of the furniture was custom-designed for the project: brass elements, the marble washbasin, even the natural leather sofa that resolves a corner like an architectural piece.

Black oak, brass, stainless steel, soft pinks, whites, black marbles, leather, and cement finishes come together in a sober yet refined palette—balanced by playful contrasts, reflective and matte, smooth and rough, simple and complex.
