Modular construction and inexpensive materials make this storage shed easy to build and easy to afford. Arch-top windows and a custom door even gives this storage shed a high-quality look that belies its low cost and simple construction. The panelized construction technique means you could build the parts in your garage on a rainy weekend and then haul them to the site for assembly. And modest finishes like OSB siding and composite trim and fiberglass shingles help keep the materials cost low. The modular construction and wood platform foundation mean you can construct this storage shed almost anywhere, even on remote or sloping sites.
