A foldable portable building can be collapsed to fit within the outside dimensions of an internationally standardized (ISO) goods container to facilitate mechanical handling and transportation. The building comprises a rigid main support having a main floor section, a main wall section and a main roof section. When the building is extended, generally horizontal and planar, hingedly interconnected floor sections and roof sections extend from the main floor and roof sections respectively, and wall sections extend between the said sections. The wall sections comprise an end wall section, two first wall sections and two second wall sections which are hingedly interconnected similarly to a bellows. When the building is collapsed, the wall sections are located adjacent the main wall section, the roof sections are disposed vertically on a side of the wall sections remote from the main wall section, and the floor sections are disposed vertically outwardly of the folded wall and roof sections. The roof sections form a foldable roof system comprising a base ceiling member, trusses and an outer roof member. The trusses are parallel to each other and extend generally across and are hinged to the base ceiling member. The outer roof members lie on chords of the trusses. Minimal vertical space is required for the collapsed roof system which enables a relatively high ceiling to be obtained, and yet still fit within the standardized container sizing.

A foldable portable building, comprising, when erected: (a) a main support comprising a main floor section, a main wall section and a main roof section, the main wall section being supported on the main floor section and supporting the main roof section, the sections being rigidly interconnected, (b) a plurality of generally horizontal and planar hingedly interconnected floor sections, including a first floor section hingedly interconnected to the main floor section, (c) a plurality of generally horizontal and planar hingedly interconnected roof sections a spaced above the floor sections, and including a first roof section hingedly interconnected to the main roof section, and (d) a plurality of generally vertical, hingedly interconnected wall sections comprising at least one transversely disposed end wall section, two first wall sections and two second wall sections, the first and second wall sections being disposed adjacent opposite ends of the floor sections, the first and second wall sections having adjacent side edges hingedly connected to each other and opposite side edges hingedly connected to the main wall section and to the end wall section respectively to form a bellows shaped connection, at least one of the first, second or end wall sections being supported and guided by the floor sections as the wall sections move between retracted and extended positions thereof, upper edges of the wall sections being generally co-planar to each other to support thereon the roof sections extending therebetween, the upper edges of the wall sections being generally co-planar with a lower surface of the main roof section of the main support, the roof sections further comprising: (i) at least one base ceiling member supported by the wall sections; (ii) a pair of outer roof members, each outer roof member being hingedly connected to an opposite end edge of the base ceiling member for rotation of the outer roof members about respective axes of rotation relative to said base ceiling member; and (iii) a plurality of trusses disposed parallel to each other to extend generally across the base ceiling member from the opposite end edges thereof, the trusses being hinged for rotation relative to the base ceiling member to permit rotation of the trusses from retracted positions thereof in which the trusses lie generally parallel and adjacent to the base ceiling member, to extended positions thereof in which the trusses extend vertically from the base ceiling member, each truss having a sloping top chord reaching an apex, wherein the trusses lie generally horizontally between the outer roof members and the base ceiling member when in the retracted position, and wherein the outer roof members rest on the top chords of the trusses when the trusses are in the extended positions thereof.
