CORTEN COURTYARD ADU
Ann Arbor, MI (Unbuilt, 2020)
Project Size: 770 SF
This 770-square-foot accessory dwelling unit is designed as a contemporary extension of the primary residence, connected by a covered walkway while maintaining its own identity and sense of privacy. Sited within a semi-urban backyard, the ADU establishes a series of carefully defined outdoor rooms that transform a modest site into a layered living environment.
The exterior composition combines weathering Corten steel with materials that complement the existing home, creating a cohesive yet distinct architectural expression. As the Corten develops its protective patina over time, stained wood elements introduce warmth and texture, weaving between steel panels and extending into the surrounding fence. Repeating the proportions and rhythm of the cladding throughout the site strengthens the relationship between architecture and landscape while reinforcing the ADU's presence within the backyard.
The open kitchen and dining area anchor the home, lifting into a lofted living space defined by warm wood finishes, built-in shelving, and abundant natural light. Rising above the surrounding fences and neighboring structures, the loft captures daylight from multiple directions and expands the experience of the compact footprint. Large windows throughout the home frame views of the courtyard, private garden, and perimeter trees, establishing a constant awareness of the landscape beyond.
The private spaces are organized around a carefully composed landscape sequence. A courtyard shared by the bedroom and bathroom draws light and vegetation into the center of the home, while a narrow garden reserved exclusively for the ADU creates a quiet outdoor retreat beyond the bedroom. Together, these spaces establish a series of framed views that connect the interior to the surrounding landscape while maintaining a strong sense of privacy.
