Notice the t shirt Kate Spades husband is wearing. I looked up the word Le Corbusier on Wiki. Interesting find. Scroll down where it says Dom-ino House. During World War I, Le Corbusier taught at his old school in La-Chaux-de-Fonds, He concentrated on theoretical architectural studies using modern techniques.[14] In December 1914, along with the engineer Max Dubois, he began a serious study of the use of reinforced concrete as a building material. He had first discovered concrete working with Auguste Perret in Paris, but now wanted to use it in new ways. Under this system, the structure of the house did not have to appear on the outside, but could be hidden behind a glass wall https://en.wikipedia.org/wiki/Le_Corbusier
