The Greenbriar from Best Barns is a prep for vinyl garage kit and is a great design for a single car garage. Prep for vinyl means that the Greenbriar exterior walls are covered with an OSB (Oriented Strand Board ) for the purpose of applying the exterior siding of your choice. You may apply wood lap siding, stucco, vinyl siding or any exterior grade siding designed to be applied to an underlay. High side walls provide plenty of room to store tall items or add shelving to keep everything organized. Available in three sizes you will find a size for all your storage and garage needs.
