Plan 135144GRA

This three-bedroom barndominium has a 1,344 square foot central garage with front and back overhead doors and a skillion, metal roof over it. Both the primary residence and the one-bedroom apartment are accessible from the 8′-deep, covered porch that runs the length of the building.

The main house, which is on the left, has an open living area that is warmed by a fireplace and a den that provides a more private spot to unwind. The main living space is finished with two bedrooms, a bathroom with four fixtures, and a big laundry room with an entrance to the garage.

In-laws, a rental property, or a young child who is ready for greater freedom might all benefit from the one-bedroom apartment that is adjacent to the right side of the garage. Corrugated metal siding is specified as the outside finish.
