A concrete slab gives the smoothest floor for rolling tools.
The drawings show footprint sizing, joist and blocking layout, drainage tips, and anchoring options based on frost depth and local wind or seismic needs.

Why This Size & Style Works
At 180 sq ft, you get more aisle length than a 10×16, which helps when parking a mower, snowblower, or long lumber. The single-slope roof pushes runoff in one direction, which is ideal along a fence or side yard. Keep frequently used tools near the side door and reserve the ends for tall shelving and bins. Choose 8 ft walls for generous vertical storage, or 6 ft for a lower profile.
