Abstract
Abstract A polygonal building having a perimeter wall made up of initially roughly plumbed rectangular wall sections in end-to-end but spaced-apart relation. Rafters extend from a common point approximately centrally of the building down to and between the upper ends of adjacent wall sections, and a perimeter cable is threaded through all of the wall sections and rafters. Tightening of the cable plumbs the wall sections, centers the rafters and thereafter prevents spreading of the roof and building when loads are imposed thereon.
