Our unique yet popular home plan could be called an apartment for a relative, set atop a three-car garage with workshop. Grandma's floor plans, at 1,029 square feet, include a spacious Great Room and master bedroom, both enhanced by wonderful window arrangements. Included in the house plans, but not in the square footage, an alternate lower-floor plan replaces two of the garage bays with two bedrooms, a lounge and a full bath, making the home live like an inverted two-story.
