This 864 sq ft two-bedroom ADU is designed above a garage, making use of vertical space to create an additional living area. The two separate bedrooms provide flexibility and privacy, while the full bathroom and in-unit washer and dryer add practical everyday convenience. A balcony offers an outdoor area above the garage, providing a place to relax without requiring a ground-level porch.
At 36' × 24', this plan uses a rectangular garage footprint to support the above-garage arrangement. The shed roof gives the exterior a clean, contemporary profile, while the design offers an alternative way to add living space without expanding the building outward.
