Abstract: A method of erecting a weather resistant transportable building enclosure is disclosed. The method includes the steps of assembling a plurality of elements to form a roof ridge, assembling a plurality of panel supporting elements to form girders of a predetermined length extending laterally from the roof ridge and pivotally attaching girders to the roof ridge. The next step is to raise the roof ridge a predetermined amount and to further attach the girders to the roof ridge to rotationally fix the pivotal attachment. At this stage a roof skeleton has been formed. Then panels can be attached onto said roof skeleton to form a load supporting roof. A final step is to simultaneously raise the roof, attach a plurality of elements to form side wall columns, and secure a plurality of panels onto the columns to form side walls for the enclosure. The enclosure is comprised of an internal rigid load supporting framework and an external load supporting surface.
