There are a number of good things about this garage apartment plan:
First, is that I can see how this plan can be made to look like a country barn.
Second, I like the fact that there is ample inside storage with room for four vehicles - the only change I'd make here is that I make the garage drive-thru; at least on one side.
Third, covered carports running the length on either side of this carriage house adds a great deal of flexible storage space - here I would improve the design by incorporating second story decks / balconies to create outside living space for the apartment.
Fourth, the upper level apartment provides an open concept recreation room for entertaining or relaxing along with a small kitchen.
Fifth, the floor plan offers a full bathroom with a setup as either a two bedroom or one bedroom and an office.
This coach house makes for a great guest house or in-law suite and for the work-at-home parent, an office delivers a peaceful getaway without ever leaving home.
Properly fashioned with charming country flair, this carriage house plan will complement any farmhouse.
