Site Selection

Site selection is an important step when it comes to building a shed. You should choose a location that is level, has good drainage, and is easily accessible. When selecting the site, consider the shed’s size, the purpose it will serve, and the type of foundation you want to build. The shed’s location should allow for adequate ventilation and air circulation.

Building Permits

Before constructing a large metal shed, you should seek permits from your local building department. Building codes vary from state to state, and you should ensure that your shed building complies with all the regulations. Failure to comply with the codes can lead to fines, penalties, and even demolition of the shed.

Shed Size and Style

The size and style of your metal shed will depend on the storage needs and the available space. When choosing the shed building style, consider the roof design, as it will determine the shed’s overall appearance. The most common roof designs in metal sheds are gambrel, gable, and lean-to. The size of the shed should be determined by the amount of storage space required and the available property.


The foundation is the most crucial aspect of building a large metal shed as it provides stability and support to the entire structure. The foundation can be built using concrete, pavers, or wood. When constructing the foundation, ensure that the surface is level and has proper drainage to prevent water buildup. A strong foundation will extend the longevity of the shed and prevent damages caused by shifting or settling.

Frame Construction

The next step is to build the metal frame, which will serve as the skeleton of the steel structure shed. The most common metal used for framing is steel, and you can purchase pre-cut or custom-made frames. The metal frames should be bolted to the foundation to create a stable structure.

Wall Construction

The walls can be constructed using metal panels, which are available in a variety of colors and materials. The metal panels can be interlocked or screwed together to create a tight seal. Windows and doors can also be installed as part of the wall construction.

Roof Construction

The final step is to construct the roof. The roof can be made using the same metal panels as the walls or corrugated metal sheets. Metal roofs are durable against extreme weather conditions, and they require less maintenance than other roofing materials.


Building a large metal shed is a cost-effective and efficient solution for your storage needs. With proper planning and construction, you can have a sturdy and reliable shed that will serve you for years to come. When building a metal shed, ensure that you comply with all the building codes and regulations in your area. A well-built shed will enhance your property’s value and provide a secure and aesthetically pleasing storage solution.
