NOT A STUDIO reshapes century-old apartment in barcelona

 

Located in Barcelona’s Sarrià neighborhood, Monterols is NOT A STUDIO’s renovation of a 36-square-meter apartment with a 15-square-meter mezzanine inside a residential building dating to 1919. Designed as an update to a family-owned property passed down through generations, the project removes decades of partitions to recover the original volume of the home and foreground its nearly five-meter ceiling height. By exposing the structure of the apartment and introducing a vivid palette of blue, green, and yellow, the intervention transforms a compact historic interior into an open loft organized around light, height, and flexibility.

 

Originally arranged as four rooms, a kitchen, dining room, and a bathroom located on the terrace, the apartment had undergone a previous renovation two decades ago that added a mezzanine. Despite this intervention, the home remained fragmented and lacked natural light. The redesign strips the space back to its essentials, creating a single continuous volume where the vertical dimension of the building becomes the defining spatial feature.

Rather than concealing the building’s age, the Barcelona-based practice NOT A STUDIO highlights original structural components and incorporates them into the architectural language of the interior. Beams and columns appear in shades of blue, green, and yellow, turning functional elements into visual markers that help organize the open-plan layout.

 

The color palette extends throughout the apartment, from a blue arched lighting feature suspended above the kitchen to green structural supports and pale cabinetry. Exposed masonry, plywood joinery, stainless steel surfaces, and tiled walls introduce material contrast while preserving traces of the building’s history. The intervention avoids reconstructing a historic interior and instead creates a contemporary layer that coexists with the original fabric of the apartment.

 

In a district characterized by traditional residential architecture, the project offers a more playful domestic environment. Color is used as a way of emphasizing the apartment’s structural framework and defining different zones within the compact footprint. 

 

The project demonstrates how small urban apartments can be reconfigured through subtraction. By removing layers of compartmentalization and revealing the building’s original structure, the renovation reinterprets a long-held family home for contemporary living while maintaining a visible connection to its past.
