A lean-to is an open roof cover attached to the main structure. Lean-to's are typically between 8’ and 16’ wide. The lean-to option is very popular for inexpensive covered storage. It can be used to store cars, boats, RV’s, farm equipment, firewood, dog kennels, etc. Some covers have a designated area for hot tubs, BBQ's and patio furniture, which allows them to be used for relaxation purposes. When designing a building take this affordable option into consideration.
