This 600 sq ft one-bedroom ADU is designed for conversion from a two-car garage, offering a way to create additional living space within an existing structure. The separate bedroom provides privacy, while the full bathroom and dedicated laundry room add useful everyday amenities. Reworking an existing garage can make this an interesting option for homeowners looking to adapt underused space on their property.
At 30' × 20', the rectangular footprint provides a wider layout than some compact one-bedroom plans. The hip roof gives the structure a traditional exterior profile, while the design is organized around an existing garage footprint.
