1How it is built
The cabin is roughly square rather than tall and narrow, giving a 60-inch turning circle inside. The door is wide and hinged to swing clear, the threshold sits flush with the ground so a chair rolls straight in, and grab bars run either side of the seat at transfer height.
2Where it goes
On firm level ground with a clear approach — no gravel lip, no cable ramp across the doorway, no unit crowded up against the door swing. At an event it belongs at the end of a bank of standard units on the accessible route, not tucked away on its own behind the stage.
3What organizers should know
Public events are generally expected to provide accessible units in proportion to the total, and inspectors do look at placement as well as count. Tell us the layout and the total unit number and we will tell you what the split should be.
