In September of 2015, The literary magazine A Public Space commissioned a small project on the work of architect Natalie de Boise. Working under the Skidmore Owens and Merrill’s infamous design partner Gordon Bunshaft, Du Boise contribution to a major body of iconic 20 century buildings has been overlooked. This small sketch project, essentially a walk down Park Avenue looking for the buildings she had a hand in, is a homage to the intensity and rigor of her architectural mind. Natalie De Bloise work on Manhattan’s Park Avenue is a series of meticulously calibrated techtonic experiences that people inhabit. Looking at the three buildings together,Pepsi Building, 1960, Lever House 1959, and the Union Carbide Building, 1961 in New York City, is a study in the precision of the architectural column, and the nuance of glass. Each building is an essay in measure and mathematics resulting in the glorious celebration of the abstraction of space.
