An emergency shelter includes a domed foam structure that is constructed on-site or at a remote location from foam that can be mixed on-site. The structure can be made on-site by spraying foam in a flowable state in a predetermined pattern to build up walls to form a dome. The foam can be sprayed, for example, in a substantially helical pattern from a centrally located spray nozzle that is rotated to deposit a finite-thickness increment of foam over a time period sufficient that, by the time the nozzle reaches a previously sprayed area, the foam already deposited has had time to cure.

What is claimed is: 1. A method of forming a shelter structure in situ comprising the steps of:providing a source of water at a site on which it is desired to erect a shelter structure;mixing foam material precursors with the provided water to form a structural foam;spraying the formed structural foam in a plurality of layers in an upwardly extending helical pattern of decreasing diameter on the site to free form a domed structure having a foam wall defining an interior space; andcutting through the foam wall to form a passage into the interior space.
