A 20×20 base building package is big enough to fit several standard-sized cars or could be used for a variety of purposes such as a workshop, or as extra external storage.
Having a prefabricated kit could mean that your base building package could only take a few weeks to build, or even a few days, depending on the size and complexity of the building.
Steel is also a robust material which is resistant to the weather and things like rust, which means that you can keep your cars or your possessions safe.
