This project reimagines the typology of the Chicago Three Flat—a common multi-family housing model rooted in the city’s urban fabric. By challenging conventional layouts and compartmentalized living, the design proposes a more integrated approach to domestic space. The Three Flat seeks to explore new relationships between public and private life within a shared building structure, fostering both spatial fluidity and communal interaction.
Building on ideas first explored in Ardmore House, we asked what would happen if circulation was removed from both the building and the apartment unit.

Two independent stair towers flank the rectilinear volume, eliminating internal vertical circulation and freeing each unit to function as a continuous living space.

The project retains the straightforward construction of the three-flat while rethinking its interior as an open, shared domestic environment.

A continuous, curving corridor connects the short ends of each unit, doubling as living, dining, and lounge space.

A curving transom marks the transition between shared and private areas, and reads as a continuous backdrop to the various programs it hosts.

Angled walls fracture beneath the curve, defining the boundary of the private rooms.

Building on Ardmore House, the reading of the circular form balances the depth of the unit to accommodate bedrooms alongside expanded spaces for living, reading, kitchen, and dining.

The kitchen spans the width of the building, bridging the two sides of the curving wall.

Fractured geometries produce shallow thresholds and niches that create more intimate zones within the larger shared interior.

A simple three-level stack with circulation moved outside of the building envelope supports efficient construction. Four Juliet balconies along the facade bring natural light deep into each unit.
