Le Corbusier developed the Domino house system, where the main concept was to:

A. separate the load-bearing structure of the house from the walls, allowing the walls and windows to be located freely
B. allow for the entire house to be disassembled, flat-packed, then shipped anywhere in the world for reassembly
C. enclose the house with mechanically fastened metal panels that could be easily disassembled and moved
D. mechanically stack vertical sheets of concrete so that they formed the exterior envelope of the house, eliminating the need for piers
