Spanning 650 square feet of heated living area, the Winthrop Adu is a specialized carriage house design that prioritizes compact efficiency and vertical utility. Measuring 31 feet 8 inches in width and 25 feet in depth, this two-story structure is engineered for narrow lots or properties requiring an accessory dwelling unit (ADU) with significant vehicle storage.

The upper level encompasses the entirety of the 650 square feet of living space, containing one bedroom, one full bathroom, and a kitchen. A dedicated keeping room provides a central gathering area, while an attached 60-square-foot deck expands the usable footprint for exterior access. The inclusion of a second-floor laundry area consolidates household management into the private living quarters.

The ground level is dedicated to a 650-square-foot, two-car garage, providing a high-capacity footprint for vehicle storage or a workshop. With 9-foot ceiling heights on both the first and second levels, the interior volume creates an open feel despite the compact floor plate. The design utilizes durable 2x6 wall framing, ensuring structural integrity for this multi-use building.

Architectural specifications include a 10:12 roof pitch and a maximum building height of 25 feet, resulting in a distinct roofline profile. This configuration is optimized for those seeking a rental income property, guest house, or personal retreat, ensuring maximum utility from a minimal land footprint.
