When you need a pure function, this 8x16 lean-to shed will give you exactly that. It’s simple to build and has a highly functional double-door that measures 64 inches across. A shed with such a wide door makes it possible to store larger equipment inside it, like snow machines and snow blowers that would otherwise take up room in your garage when they’re not being used.
Although this shed lacks windows, it provides ample ventilation in the form of wall vents so that fumes won’t build. Place the shed so it faces south or west and you can install solar panels on its sloped roof. There’s plenty of room in the wall cavities to run wiring for lights and outlets. You can also install a locking mechanism on the door to protect your property.
