Adu 313 is a compact, two-story carriage house plan designed with a 22-foot by 22-foot footprint, making it an efficient solution for properties requiring an accessory dwelling unit. This design provides 484 square feet of heated living space on the upper level, positioned directly above a 484 square foot 2-car garage, allowing for maximum utility without expanding the primary residence's lot coverage.

The second-floor living quarters feature an open-concept layout that integrates the kitchen and living area, creating a sense of scale despite the modest floor plate. A single bedroom and one full bathroom are contained within this floor, providing a self-sufficient living environment suitable for a rental unit, guest suite, or dedicated office space.

Vertical volume is prioritized through 9-foot ceiling heights on the second floor, which enhance light penetration and the overall feeling of space. The ground level garage maintains an 8-foot ceiling height, offering sufficient clearance for two vehicles while serving as the structural base for the living quarters above.

Constructed with a 23-foot 5-inch maximum building height and an 8:12 roof pitch, the structure maintains a classic profile consistent with traditional and craftsman architectural styles. The compact square footprint ensures ease of site placement, while the separation of the garage and living levels maintains a distinct division between utility and residential zones.
