This small hall type has a basket-weave brick floor, the roof supported on pipe columns that float free of the brick walls. The exterior corners are Mies-inspired, while the window treatments are a take on Richardson’s Sever Hall at Harvard. Details of that window system are below: elevation/section, axon of the base, worm’s eye of the head. I owe you roof-ceiling information – but the question remains, bow truss or hammer beam? Or something altogether different?
