Sheds are most commonly made with steel, wood and vinyl and are available at most home improvement retail outlets, garden centers and greenhouse supplier outlets. Sheds are used for gardening, storage, tools and woodworking and add creativity to your yard. It is important to locate your shed on level ground with good drainage. The type of foundation required will depend highly on the type of shed you have and the construction of the foundation can make or break your shed-building experience. Some sheds serve multiple duties as a greenhouse, solarium, or even an office. A 60-square-foot cedar shed with the basic necessities will cost approximately $2,100 and will take about 4 to 5 hours to assemble.
