THE COTTAGE ADU STANDARD PLANS

Design details such as open shelves in the bathroom, corner under-counter cabinets to maximize storage, and outdoor access from the bedroom further encourages the space’s open feel. One larger bedroom (~120 sq. ft) can fit a king bed and offers privileged backyard access. The two bedrooms also share a generous bathroom with a full tub and in-unit stackable washer-dryer.
