Abstract: A shelter construction shelters users and vehicular or vehicular-sized gear. The shelter construction comprises a central canopy assembly and one or more laterally-situated collapsible/expandable enclosures. The central canopy assembly comprises a canopy and canopy-elevating structure. The canopy comprises an outer canopy surface, an inner canopy surface, longitudinally-opposed gates, and at least one set of laterally opposed portholes. The gates and portholes let users and gear therethrough. The enclosure(s) are attached to the outer canopy surface adjacent the portholes for enclosing users and gear as let through the portholes. The enclosures each comprise a roof section, a floor section, a wall section, and enclosure-elevating structure. The floor and wall sections are sized and shaped to as to enable a novel method of erecting the shelter construction and for maintaining the enclosures in a neat, compact assemblage when in a collapsed state.
