A shelter including a wall unit having walls. Each wall has a top edge, a bottom edge, and opposite side edges extending between the top and bottom edges. Each side edge is joined to a corresponding side edge of an adjacent wall to form a corner of the wall unit. The wall unit includes an access port in at least one wall. The shelter includes an upper rigid shell having a central portion surrounded by a channel for receiving the top edges of walls of the wall unit so the upper shell forms a roof of the shelter. The shelter includes a lower rigid shell having a central portion surrounded by a channel for receiving the bottom edges of walls of the wall unit so the lower shell forms a floor of the shelter.

1. A temporary shelter comprising: a wall unit having a plurality of walls, each wall having a top edge, a bottom edge opposite the top edge, and opposite side edges, each of said opposite side edges having a length extending between the top edge and the bottom edge, each of said opposite side edges being joined along at least a portion of its length to a corresponding side edge of an adjacent wall of the plurality of walls to form a corner of the wall unit, said wall unit including an access port in at least one wall of said plurality of walls for at least one of entering and leaving the shelter and viewing objects outside while inside the shelter;an upper rigid shell having a central portion surrounded by a channel sized and shaped for receiving the top edges of walls of the wall unit so the upper shell forms a roof of the shelter; anda lower rigid shell having a central portion surrounded by a channel sized and shaped for receiving the bottom edges of walls of the wall unit so the lower shell forms a floor of the shelter;wherein each of the channels comprises opposing vertical side walls connected by a horizontal wall, wherein the horizontal walls are disposed between an uppermost end and a lowermost end of the shelter. 2. A shelter as set forth in claim 1 wherein the upper rigid shell includes a rim extending around its channel surrounding the lower rigid shell when the upper rigid shell is positioned in face-to-face relation with the lower rigid shell. 3. A shelter as set forth in claim 2 wherein the wall unit is collapsible for positioning between the upper rigid shell and the lower rigid shell when the rim surrounds the lower rigid shell and the upper rigid shell is positioned in face-to-face relation with the lower rigid shell. 4. A shelter as set forth in claim 3 wherein the wall unit is collapsible for positioning between the upper rigid shell and the lower rigid shell when the rim surrounds the lower rigid shell and the channel of the upper rigid shell is positioned in face-to-face relation with the channel of the lower rigid shell. 5. A shelter as set forth in claim 4 wherein the wall unit consists of four walls, two opposing walls being foldable inward at their respective centers for collapsing the wall unit. 6. A shelter as set forth in claim 5 wherein two opposing walls are foldless. 7. A shelter as set forth in claim 6 wherein the access port comprises a door cut in one of said two opposing foldless walls. 8. A shelter as set forth in claim 7 wherein the access port comprises a window cut in each of said walls of said plurality of walls. 9. A shelter as set forth in claim 2 wherein the upper rigid shell and the lower rigid shell are identical except that the upper rigid shell includes the rim. 10. A shelter as set forth in claim 2 wherein the rim of the upper rigid shell is uninterrupted. 11. A method of assembling the shelter of claim 1, said method comprising the steps of: unfolding the wall unit, thereby forming a tubular wall unit;orienting the lower rigid shell so the channel of the lower shell faces upward;inserting the bottom edges of the plurality of walls of the unfolded tubular wall unit in the channel of the lower shell; andpositioning the upper shell on the plurality of walls so the channel of the upper shell receives the top edges of the plurality of walls of the unfolded tubular wall unit, thereby forming the shelter. 12. A method of preparing for transport a shelter comprising a wall unit, an upper rigid shell, and a lower rigid shell, said method comprising the steps of: removing the upper shell from the wall unit;orienting the upper shell so a channel of the upper shell faces upward;lifting the wall unit out of a channel in the lower shell;folding the wall unit to a flat configuration;positioning the folded wall unit on top of the upward oriented upper shell so the wall unit lays against a face of a flange of the upper shell and the wall unit is entirely received in a rim surrounding the upper shell;positioning the lower shell so the channel of the lower shell faces the folded wall unit, so a face of a flange of the lower shell lays against the wall unit received in the rim of the upper shell, and so the rim of the upper shell surrounds the flange of the lower shell; andjoining the upper shell and the lower shell to hold the wall unit between the upper shell and the lower shell.
