<p>Currently portable industrial camp shelters will be either wood frame construction or fabric tents. The former have restrictions on size and require special skills and equipment to install on site. The latter require plumbing and electrical installation to be installed on site. The present invention combines the advantages of frame structures and tents in a portable collapsible shelter by modifying standard shipping container structures (10) to provide fold-down side walls (12) which extend the floor space of the container and are provided with a retractable fabric cover (60) to enclose the extended space.</p> |
