House Plan 8017 is an amazing design for multigenerational households or a family looking for rental income to offset the mortgage. Why? Because the floor plan includes 3,147 square feet in the main house and 959 square feet in an apartment above the three-car garage. The main house includes open living, the master suite, and a den on the main level while a smaller bedroom suite and two bedrooms that share a hall bath are located upstairs. The apartment has its own entrance and staircase behind the garage and connects to the loft on the second level, too. With a full kitchen, living space, two bedrooms, a bathroom, and laundry, in-laws or tenants will want for nothing!
