Shadow House is a proposed two-storey extension to the southwest side of an existing 1958 Case Study-style residence in Ann Arbor, Michigan. The new structure follows the natural slope of the site, extending along the southern edge of the property and connecting to the elevated, open-plan living room of the original home.

A secondary entrance, accessed via a footpath on the east side, leads directly into a new kitchen and living area located at grade. From this point, the building’s angled form incorporates a stairway that ascends to two bedrooms and a bathroom, ultimately linking to the existing residence. This architectural inflection is designed to preserve the original home's sightlines and spatial openness.

Modest in scale compared to its larger neighboring homes, the addition respectfully situates itself in the metaphorical and literal shadow of the original structure.
