The most popular space to rent that I have found is a 10 foot by 10 foot storage shed. A 10 foot by 10 foot space is 100 square feet, about the size of an average bedroom. A 10x10 foot shed will typically hold the furnishings of a one bedroom apartment plus appliances and other miscellaneous items. Approximately three rooms worth of furniture will fit in a 10x10. This size is also excellent for storing away files in file boxes. A 10x10 foot unit will hold about 108 standard file boxes on shelves for easy access, or 168 file boxes without shelving or aisles.
