Adu 316 is a compact carriage house design that optimizes its 623 sq ft footprint by placing the primary living quarters above a 484 sq ft, 2-car front-load garage. Measuring 22 ft wide by 26 ft 6 in deep, this structure is engineered for narrow or compact lot configurations, providing a efficient vertical solution for rental income or private guest accommodation.
The first level consists of 59 sq ft of heated space, housing a dedicated mud room and entry point designed to manage traffic flow before ascending to the upper level. With 11-foot ceilings throughout the ground floor, the entry remains proportionally balanced, leading into the primary residential area located on the second floor.
Spanning 564 sq ft, the second floor serves as the core living environment. This level includes a full kitchen with an island, a designated home office, and a private bedroom suite. The 11-foot ceiling height in the living and bedroom zones creates a consistent vertical volume, ensuring the interior feels expansive despite the modest total square footage. An 8:12 roof pitch defines the upper profile, contributing to a total building height of 26 ft 5 in.
Constructed on a slab foundation with 2x4 framing, the design focuses on structural longevity and ease of build. The integration of the 2-car garage at the base allows the living space to remain elevated, providing better natural light penetration and separation from the utility zones. This carriage house configuration effectively separates automotive storage from the living environment while maintaining a small overall footprint.
Key Features: 623 sq ft total living area, 2-car front-load garage, 1 bedroom, 1 full bathroom, dedicated home office, kitchen island, 11-foot ceilings, slab foundation, 8:12 roof pitch, compact footprint.
