18 x 20 ft Sheds, Garages, Carports & Shelters

Protect your vehicles, tools, and outdoor equipment with IPATIO's selection of sheds, garages, carports, and shelters. Whether you need compact garden shed storage, a full-size metal garage for vehicles, or a quick-deploy carport to shield cars and trucks from Canadian winters, we carry solutions from trusted brands including Arrow and ShelterLogic.

Our storage structures feature galvanized steel panels, UV-resistant polycarbonate roofing, and pressure-treated wood frames rated for Canadian snow loads. Many models are engineered to meet local building code requirements for permanent or semi-permanent outdoor structures.

Installation-friendly designs with detailed instructions mean most homeowners can assemble these structures over a weekend. Free shipping on most orders over $88*, with expert product support available to help you choose the right size and material for your property.

*Conditions apply. See our Shipping Policy for details.


Our 18' x 20' structures provide spacious coverage for large garages and shelters. Wide enough for oversized vehicles and equipment with room to spare.
