Rosemont ADU is a compact residential solution spanning 418 square feet of heated living space. Designed with a 19-foot width and 25-foot 10-inch depth, this carriage house model fits within constrained lot footprints while providing an independent living environment above a 418-square-foot, 2-car front-load garage.
The second-floor layout maximizes the 418-square-foot interior by prioritizing a consolidated living area and a private bedroom. This configuration creates a self-contained unit that includes a full bathroom and integrated laundry access directly from the bedroom area, providing autonomy for residents or tenants. The efficiency of the plan ensures that every square foot serves a specific purpose without unnecessary circulation space.
Construction specifications include a 6:12 roof pitch and 2x4 wall framing, supported by a slab foundation. The 8-foot ceiling height in the garage provides clearance for standard vehicles and storage, while the elevated position of the living quarters ensures privacy and separation from the ground-level parking zone.
This design serves as a versatile accessory dwelling unit (ADU) for rental income, guest accommodations, or a private home office. Its narrow profile allows for integration into existing properties with limited space, providing a sustainable way to increase property utility and value through an efficient, detached structure.
