This 704 sq ft two-bedroom ADU is designed as a three-car garage conversion, creating an opportunity to turn an existing structure into additional living space. The two separate bedrooms provide more privacy and flexibility than a single-bedroom layout, while the full bathroom and in-unit washer and dryer add everyday convenience.
At 32' × 22', this plan has a wide rectangular footprint suited to a larger garage layout. The gable roof maintains a familiar residential appearance, while the conversion approach offers another way to make better use of existing property space.
