This 860 sq ft two-bedroom ADU combines two full bathrooms with the convenience of in-unit laundry. The separate bedrooms provide private sleeping areas, while the additional bathroom offers greater flexibility for everyday use. The open front porch creates an outdoor space for relaxing and adds another functional area to the design, complementing the interior living spaces.
At 43' × 20', this plan provides a rectangular footprint with room for a two-bedroom, two-bathroom arrangement. The hip roof gives the exterior a traditional residential character, while the in-unit washer and dryer help make the ADU more self-contained.
