It was Gray's first foray into architecture, and as such it was a manifesto. For Gray, the whole building--the structure, its materials, the color scheme, the windows, the hardware, the fittings, the furniture--was an experiment with new concepts of spatial relations, an attempt to create an architecture of lightness and freedom. This new publication finally places this key example of modern architecture in its rightful position in history, contextualizing the structure with essays, reproductions of archival material, photographs and numerous scale drawings.
