By converting an uninhabitable attic into a unified and light-filled volume, Mork Ulnes Architects gave new life to a 1907 Victorian flat. The formerly compartmentalized house was transformed into an expansive home centered on collective living. To host a growing family, the gabled attic level was lightly divided into bedrooms, thanks to a series of partial-height walls. A double-height stair atrium cuts into the center of the building, linking the newly habitable attic to the levels below. The attic’s wood framework is a graphic echo of the original roofline within the expanded building shell. This framework language carries throughout the project in casework details, windows, guardrails, and the kitchen.
