This roof covers the 37,000 sq. ft. entry space to Surrey Central City. A 7 ft. deep tetrahedral timber space truss with a central kingpost and cable support was an efficient means of dealing with the complex and curving geometry while also providing an aesthetically pleasing and mostly column free roof. The space truss consists of nearly four thousand Douglas Fir peeler core members, a relatively inexpensive by-product of the plywood industry.
