That's really cool! I want one :)<p>In all seriousness though I think if my property was 6' wide my first move would be build a basement and sub-basement and sub-sub-basement. The ground floor would be for my motorcycles, kitchen on the 2nd floor, den in the basement, sleeping in the sub and storage in the sub-sub. You'd barely need any square footage, especially if you use ladders instead of stairs.<p>I guess you could say I'm thinking like a submarine designer?
