Optional Item

Wood floor is 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 if from damaging moisture. Included in the floor kit are 4×4 treated runners, 2×4 treated joists (spaced 12″ on center), 3/4″ plywood flooring and nails. 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.
