A shed is an enclosed extension that attaches to the main structure, similar to a lean-to. However, instead of open sides, the shed is fully enclosed with the siding of your choice. Because it uses a lower eave height than the main building, this space is more economical to build. As a result, shed additions are a cost-effective way to gain extra enclosed space. They work well for living quarters, hobby rooms, workshops, or additional lawn and garden storage. For customers who need more room without the cost of taller height requirements, a shed is often the most affordable expansion option.
