I use an apartment as a testing zone before I tear down the décor in my medium house, and all I keep thinking is, "Gee, I would love to have no stairs or windows to work around in my home." Honestly, all I want is a Giant. Blank. Box. Double high, triple wide apartments with no windows or rafters or pillars. Let me build my own layout. Maybe make much larger lofts to make it easier, but I'd love to just design the whole thing.
