The Gold Coast Rooftop Addition transforms a four-story Chicago townhouse through a fifth-floor addition and the careful renovation of the existing house. A new stacked stair reorganizes the house, culminating in a circular rooftop courtyard. A roofscape of sloping planes set apart from each other breaks up the mass of the addition into a village-like roofscape, capturing and diffusing daylight while reducing its scale against the historic masonry house.
The rooftop's angular slopes harness sunlight, naturally directing and diffusing light.

The new stair becomes the organizational spine of the house, connecting the rooftop addition to the new sunken kitchen at garden level, bringing light down through its core.

The circular courtyard anchors the rooftop addition, bringing together landscape, curved glazing, and the fragmented roofscape into a single composition.

A single folding wall organizes the owner’s suite, forming recessed spaces for bathing, dressing, and storage. Cut sectionally by a single angled datum, the wall admits daylight while preserving privacy.

Curving walls shape the ground floor and sunken kitchen, defining an intimate conversation-pit dining area.

The back of the first floor is removed to create a sunken kitchen at garden level. Wood paneling traces the original floor datum, emphasizing the excavation while a new double-height opening brings daylight into the interior.
