This 1,200 sq ft two-storey ADU makes use of vertical space to provide a larger living area within a relatively compact building footprint. The two bedrooms offer separate private spaces, while the two-and-a-half-bathroom arrangement adds convenience across the home. A dedicated laundry room provides another practical feature, helping keep everyday household tasks organized.
At 20' × 30', this plan has a compact rectangular footprint spread across two storeys. The hip roof gives the exterior a traditional residential profile, while the two-storey design provides additional floor area without requiring the same ground-level footprint as a single-storey layout.
