A: Best Barns shed kits are designed for the DIY homeowner. Home Depot doesn't provide installation but you may check at your local Home Depot Pro Desk as they may have contractors that could assist you with the construction.
If you have heavy equipment you should consider the Mansfield 12 ft. x 12 ft. Wood Storage Shed Kit with Floor including 4x4 Runners. This comes with 3/4" plywood flooring rather than 5/8" OSB with the standard floor. See product link below.
Shingles are not included. Windows are optional and not included.
