This proposal is a flat packed temporary shelter that is based on a similar volume to that of an ISO 20’ x 8’6” dry freight (shipping) container. The units have been designed so when they are collapsed four units can be transported within the volume one container with minimal working tolerance around the packs so as not to waste any space. Each pre- assembled building package is erected by removing the pins that secure the base panel and turning it through 180 degrees, this then forms the roof element held in place by the same pins. Prior to fixing the roof panel, both the hinged walls are folded up from the base and the end window elements, are inserted. All window elements are stored for protection during transport in recesses on the interior face each of the hinged panels. The rebated panel junctions and the double sealed knuckle hinges make the shelter completed water and dust proof. Both molded walls are designed to receive and hermetically store water either harvested from the roof or delivered to. The estimated maximum water capacity of both the walls is 2240 litres and when dry, the transport weight of a single unit is calculated to be 247 kg. Further weight reduction will be able to be achieved by analyzing the structure more closely and optimizing the amount of plastic used in each element.
We see this shelter being used in situations where rapid deployment is required and where secure and sterile conditions are necessary, such as a field hospital. The insulating qualities of the panels are good and therefore it could be used in a range of environments with the further benefit of the material lending itself to being cleaned regularly and being able to be maintained in a sterile condition. These units have also has been designed to be partitioned internally if segregation is required and there are further fixtures and fittings have been designed that could be introduced to provide simple elements such a tables and bunk beds. Again a super graphic symbol or identification number can be easily produced by inserting removable disks into the dot matrix of circular surface deformations that have been designed to stiffen the exterior surfaces of the wall panels.
