Dom-Ino House

Le Corbusier – Cité-jardin aux Crêtets – La Chaux-de-Fonds, Suisse, 1914

Dom-Ino House (French: Maison Dom-Ino) is an open floor plan modular structure designed by noted architect Le Corbusier in 1914–1915.
It was a prototype as the physical platform for the mass production of housing. The name is a pun that combines an allusion to domus (Latin for house) and the pieces of the game of dominoes, because the floor plan resembled the game and because the units could be aligned in a series like dominoes, to make row houses of different patterns.
This model proposed an open floor plan consisting of concrete slabs supported by a minimal number of thin, reinforced concrete columns around the edges, with a stairway providing access to each level on one side of the floor plan. The frame was to be completely independent of the floor plans of the houses thus giving freedom to design the interior configuration. The model eliminated load-bearing walls and the supporting beams for the ceiling.
This design became the foundation for most of his architecture for the next ten years.
