I claim: 1. A plastic resin building having a base, panels, and a roof, said panels being connected at a bottom end to said base, at a top end to said roof and to each other at first and second longitudinal edges, wherein:
said base includes lateral fasteners having a body and a head of increased diameter than said body, said fasteners spaced apart and extending outward from said base; and said panels having a first wall and a second wall, said first wall defining downwardly opening fittings spaced along the bottom end so that said panels can be mounted to said base by sliding said fittings onto said fasteners and tightening said fasteners, wherein said fittings include raised surfaces that can engage said fasteners when tightened to prevent vertical dislocation of said panels from said base. 2. The resin building of claim 1, wherein said panels have a first flange at said first edge defining longitudinally spaced projections and a second flange at said second edge defining longitudinally spaced depressions, said depressions being located and sized to receive said projections of an adjacent said panel so as to prevent separation of said panels.
a door having a free edge and an opposing hinged edge at which said door is pivotally attached to said door panel, said door having a first wall and a second wall, said first wall defining a recess adjacent to said free edge and concentric with a pivot axis, said recess defining projecting open and closed stop surfaces; and a latch centered about said pivot axis and having a unitary base sized to fit within said recess, said base having projecting open and closed catches respectively matable with said open and closed stop surfaces, said open and closed catches radially spaced apart so as to limit the pivot of said latch to approximately 90 degrees; said latch having a handle with a latching end extending beyond said free edge when said latch is closed. 11. The resin building of claim 10, wherein said first and second walls include openings at a bottom of said recess in said door for viewing said base of said latch from outside said building, said base having an occupancy indicating surface having a first marker representing said latch being fully closed and a second marker representing said latch being fully open.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The outdoor structure, or building, of the present invention is indicated generally by reference number 20 of FIG. 1. In general, the outdoor structure 20 comprises a base 22, side panels 24, a door frame panel 26, a door 28 and a roof 30. As best shown in FIG. 14A, the base 20 is made of a plastic wood material (solid recycled plastic) and has two transverse feet 32 that are slightly longer than the structure 20 and approximately 4″ wide. The feet 32 have front and rear tapered ends 34, oriented to taper downward toward the structure 20 so as to facilitate sliding the structure 20. The feet 32 support transverse and lateral members 36 fastened together to form an essentially rectangular framework 38. The framework 38 in turn supports a floor board 40, roughly �″ thick and covering approximately the front half of the framework 38. The rear half of the framework 38 supports the elimination or septic tank 42, shown in FIG. 14B and discussed in detail below.
As best shown in FIGS. 11A-11B, the door 28 is also formed to include a rectangular handle 254 near the center of the free edge 256 of the door 28. The handle 254 projects outward so as to define a pocket 257 for receiving a person's hand when opening the door 28. Located laterally inward from the handle 254 are formed a circular recess 258 and a center opening 260 which receives a washer 262 and a bolt 264 so as to secure the inside door latch 266 to the door 28. An arcuate occupancy window 268 is formed adjacent to the recess 258 to allow viewing of the red, �in use� or green, �not in use� portions of the indicator decal 270 adhered to the latch 266.
The preferred method of assembly of the toilet embodiment of the structure 20 is shown in FIGS. 14A-14D. To assemble the structure, the base 22, with the floor board 40 attached, is laid on a flat surface and the bolts 44 in the base 22 are backed out approximately �″. Then, the back wall panel 24 is assembled to the back of the base 22 by placing the receivers 46 over the bolts 44. Then, the tank 42 is placed onto the base framework 38 with the top 122 and bottom 124 of the tank connected together. The tank 42 is tilted backward slightly so that the tabs 120 can be fit within the slots 118 in the T-projection 106 of the rear wall 24, at which point the tank 42 is set in place and the bolts 44 are tightened to hold the rear wall 24 in place. Then, the side walls 24 are assembled by fitting the tank tabs 42 in the T-projection slots 118 and the receivers at the bottom of the panels over the bolts 44, which are then tightened. The flanged edges 88 of the two rear corners of the side panels 24 are joined together by sliding the corners 50 within the edge channels 82. The front panel 26, with the door 28 hinged thereto, is assembled to the base by resting the bottom of the panel on the feet 32 of the base 22 and screwing the threaded fasteners 49 through the bottom of the panel and into the base 22. The flanged edges 88 of the side 24 and door frame 26 panels then are joined together by sliding the corners 50 within the edge channels 82. And, bolts 91 are disposed in the cross-drilled bores 93 and 101 and tightened to nut 95 so as to secure the panels 24 to the base 22. The roof 30 is set on top of the assembled panels 24, 26 and the bolts 44 are inserted through fitting slots 56 fit and the bolts 44 are tightened. Finally, the venting pipe 415 is then inserted into the cylindrical aperture 182 in the tank top 122.
