This design is now on display at the Vermont Factory, take the tour, see how they are made and walk into a huge display yard including a 14×20 One Bay Garage.
This one is an original design by JCS. Its (2) 10-light primed barn sash windows are both hinged to open out. Additional windows available for purchase can be placed anywhere in this design allowing extra light and enhanc- ing the spaciousness of this garage. The roofing mate- rial is corrugated evergreen metal. There is no floor to worry about rotting away. We recommend laying down a concrete slab. The 8×14 loft means plenty of room for additional storage.
