Reiulf Ramstad Arkitekter recently completed their latest residence: a multi-family dwelling set atop a steep slope in Oslo, Norway. As with the Norwegian architecture firm’s many other projects, the home is primarily clad in vertical planks of natural timber which tie the building into its wooded surroundings. Named the Two-in-One House, the residence houses two families as well as an independent apartment.

When the client came to Reiulf Ramstad Arkitekter with the project, the brief asked for a house that could comfortably accommodate two families while appearing as a single, unified home. In response, the architects crafted a slender and rectangular cedar-clad volume that emerges from a concrete base. To give the monolithic building a sense of lightness and to take advantage of surrounding views, the building is wrapped in glazing on the lower and top-most levels.

“The main task was for the project to appear as a unify house despite its duality, and still ensure the privacy of both units,” wrote the architects. “The ground floor integrates the main public functions of the homes and elegant windows frame the landscape scenery and invite nature into the building. On the contrary, the first floor protects the intimacy of the families and provides a more introvert area, with windows subtly appearing behind the cedar cladding.” The contemporary home also connects to a series of outdoor terraces on the east.
