Located in Berlin's Karlshorst Rheinisches Viertel, RPA19 reimagines a single-family home from the 1920s as a site of subtle transformation. With approximately 200 square metres of floor space, the residence underwent a radical yet respectful spatial reorganization. Walls were removed to open up the view and merge spaces, particularly around the kitchen and dining area, while preserving the home’s essence.

Each intervention speaks of a reverence for the past, paired with a forward-thinking approach to materials. Natural plaster cloaks the walls in a warm, earthy tone, while carefully restored baseboards and stair railings reaffirm the home’s historical essence. The material language follows a strict yet poetic logic: brushed stainless steel is juxtaposed with richly grained elmwood, creating moments of calm tension throughout the built-in elements.

The kitchen, conceptualised as the heart of the home, is both an object and an architectural feature. A stainless steel island appears to levitate atop a wooden plinth — an elemental monolith in dialogue with a recessed niche holding the sink, framed by bespoke cabinetry. This interplay of mass and void, volume and plane defines the spatial experience.

A custom-designed hallway wardrobe mirrors the kitchen’s material syntax, featuring handmade door handles bearing VAUST’s unmistakable fingerprint. The furniture concept merges collectible design and curated restraint. FRAMA pieces are paired with rare finds, such as the RM Chair by LS Gomma and the Doodle Stool by Aleksander Oniszh. Vintage pieces, such as seating by Kazuhide Takahama, are layered with VAUST's own designs — each item is carefully chosen to contribute to the home's quiet radicalism.

RPA19 is an homage to architectural memory and material integrity, where the future is built by refining the past rather than erasing it.
