In the historic heart of Barcelona’s Raval district, a striking transformation has turned a cramped 19th-century apartment into a contemporary micro-living masterpiece. Designed by French architect Octave Petit, the 36m² space challenges conventional small-space design with an intelligent layout that maximizes light, air, and functionality while preserving the building’s original character.
Originally a three-bedroom apartment, the compact dwelling has been reimagined for 21st-century urban living, catering to a single person or couple. Petit’s approach was radical yet respectful—stripping away the old partition walls to create an open, fluid space that connects the two opposing facades, one facing the bustling street and the other overlooking a quiet courtyard. The only elements retained were the original load-bearing walls, which were carefully restored and left exposed, adding a raw, textured contrast to the sleek modern interventions.
The most daring move was placing the bathroom at the center of the apartment. Rather than concealing it, Petit designed it as a freestanding sculptural piece of furniture, clad in translucent panels that diffuse natural light while maintaining privacy. This central volume acts as a subtle divider, separating the living area (oriented toward the lively street) from the bedroom (facing the tranquil courtyard), without obstructing sightlines or airflow.
Along one of the preserved structural walls, a second multifunctional furniture piece integrates a compact kitchen and wardrobe storage, serving both the living and sleeping zones. The minimalist design ensures every element has a dual purpose, reinforcing the studio’s efficient use of space.
Materials were chosen for their honesty and durability—concrete, glass, and untreated wood create a tactile, understated aesthetic that harmonizes with the building’s historic fabric. The restrained palette keeps the focus on the play of light and shadow, which shifts throughout the day as sunlight filters through the apartment.
Octave Petit’s Studio Raval is a great example of how innovative architecture can transform even the most challenging spaces. By embracing constraints and rethinking traditional layouts, the project offers a blueprint for sustainable urban living—where every square meter is thoughtfully curated, and history coexists with modernity.
For those seeking inspiration in small-space design or Barcelona’s evolving architectural scene, this project proves that limitations can spark the most creative solutions.
