Air Unit

Last week, Toronto's Lateral Architects premiered a brand new "deployable condo unit... that is light as air."

Lateral's "exciting new freehold residential unit" not only attaches to the sides of existing buildings – indeed, it is "a portable unit that can fit into any community and be attached to any building" – but it also floats on water.
Fill it will helium, meanwhile, and perhaps it will even float on air...
BLDGBLOG would like at least three units, please.
I'll attach them to the side of the Golden Gate Bridge and telecommute.
