This is an exposed canopy for the Stauffer Center at the University of Redlands located in Redlands, California. The architect is Meyer and Allen Associates. The structure is made of Triodetic System.

The construction cost was about $17.50 per square feet with a total of $115,000. Ten workers assembled and completed the construction of the spatial structure in six days. The Lift Slab Method, in which the entire structure was assembled on the ground and was set in place with a crane, was used.

The structure has a square-on-square offset flat double-layer grid configuration with total upper layer plan dimensions of 81'-3" by 81'-3". The modules are 75" by 75" with a structural depth of 40". The structure is completely exposed without any roofing materials. All the members of the spatial structure are round steel tubes with outside diameters of 2.5", except at the supports and mid-span where 2.875" tubes are used. The wall thickness for all members is 0.148".

The structure is supported at the bottom layer by eight 24" diameter concrete columns placed along the edges of the structure. The center-to-center span of columns is 31'-3" with a 9'-4.5" cantilever along the four edges of the structure.
