Optional Wood Floor
Floor not included; Add a wood floor kit to your shed to give it a finished look!
Designed specifically for your new storage building. Adding a wood floor provides a dry storage area and raises the building above the ground protecting it from damaging moisture. Included in the deluxe floor kit are 4×4 treated runners, 2×4 treated joists (spaced 16″ on center), 3/4″ Plywood flooring and nails. The extra 4×4 runners add additional support to the floor joists and allows you to build your shed directly on the ground or grass. The 4×4’s raise the foundation above the ground for air flow that will eliminate moisture.
The material is not pre-cut and will require the customer to make simple straight cuts. The flooring package will be delivered before your shed by a local lumber dealer. They will call to make delivery arrangements and someone must be there to receive and sign.
