A 600 square foot ADU in El Cerrito that serves a dual purpose: a dynamic home office space for the property owners and an accommodating temporary residence for guests. The design concept focuses around creating a balance between the function of an office and the coziness of a home. The structure features high ceilings and large openings to the exterior to blend the limited square footage with the larger abutting patio. The architecture prioritizes flexibility, maximizing the utility of every square foot to cater to the diverse needs of its residents.
