E-1027 is a white cuboid built on rocky land on raised on pillars. According to Frances Stonor Saunders, E-1027 was formulated on Le Corbusier’s “Five Points of the New Architecture” because it is an open plan house which stands on pillars with horizontal windows, an open facade and a roof accessible by staircase. However, Gray was critical of the avant-garde movement’s focus on the exterior of buildings, writing “The interior plan should not be the incidental result of the facade; it should led to a complete harmonious, and logical life.”
According to architecture critic Rowan Moore, E-1027 “grows from furniture into a building.” By this point, Gray was fascinated by lightweight, functional, multi-purpose furniture which she called “camping style”. She created a tea trolley with a cork surface, to reduce the rattling of cups, and positioned mirrors so a visitor could see the back of their head. At the entrance of E-1027 Gray created a celluloid niche for hats with net shelves to allow a clear view without the risk of dust settling.
