What size garden building is best for a home gym?
For a functional home gym, we recommend at least a 4m x 3m space, which allows room for a treadmill or rack setup. If you plan on housing heavy equipment, a multi-station setup, or floor exercise mats alongside machines, a 5m x 4m or larger building is ideal.
What size garden room do I need for a home office?

What are the most popular garden room sizes?
