ABSTRACT:
A compact, temporary shelter that includes at least two vertical frame members aligned transversely over a base frame. Each frame member includes two opposite straight lower sections, two curved eave sections, two optional straight roof sections and a curved, central peak section. Adjacent frame members are interconnected by a plurality of purlins. The shelter includes an inner liner disposed over the inside surfaces of the frame members. The inner liner creates wall air spaces between two adjacent frame members and an upper attic and a lower living space that are partially isolated. When attached to an HVAC unit, air from the living space and flows and circulates into the wall air spaces between the frame members and into the attic. From the attic, air travels through a vent opening formed on an end cover to the outside environment. Located inside the shelter is a flexible air sock that connects at one end to the output port on the HVAC unit to evenly distribute the air into the living space. Because the frame member includes straight sidewalls and the inner lining forms a relatively high ceiling, greater storage and living space is created.
