[Irrelevant geometric comment: you only need to resize it to sqrt 2/2 (say 70,7%) to get 50% of the area. Getting users 70,7% high may not be that difficult after all, but getting miniature kitchen cabinets lighting fixtures faucets windows toilets etc. will require a bit of custom work.]
[Irrelevant architectonic comment: Le Corbusier obviously had some cost estimate headache after he had what he thought was a pretty finished design for Ville Savoye --it's nice to compare the project to-be-built published in the first volume of the Complete Works, and the finetuned shrinked project as built published in the second volume. The rooftop bedroom area got squeezed into the main story, the structural bay is a bit smaller, etc. The second design is as always happens in these cases even more awesome than the first design.]
