This 800 sf DADU was designed to complement the main house and take advantage of cool summer shade offered from a large walnut tree. The new cottage and main house form a courtyard around the tree, creating a shared outdoor space for the four generations of family living on the property. The DADU was thoughtfully designed to accommodate aging in place, utilizing universal design concepts such as, keeping the floor level close to grade, accessible bathrooms and shower room, wide doors everywhere and open spaces that allow ease of movement. These bright open spaces make the cottage seems bigger than it is.
