This is an interesting floorplan. It was developed for the boomerang and sandwich generation, or adults with kids who move back and aging parents who move in. This seems to be a recurring theme today, and this plan accommodates those shifting needs.
The main floor provides the living space for the sandwich generation as well as a separate in-law suite, complete with a small patio. The boomerang generation has its own garage and entrance that leads to the upstairs
