Well put. I feel that the very extremes are more as a proof of concept - while I've seen a family of 3 living in a 280 SF TH, they had a 1,000 SF "Office" next door. Given good design, a smaller house is not an impossible concept - ours at 800 has a pretty lousy layout, due to the building we got when we bought it - knocking out the interior demising wall could not happen due to structural issues. The overall all idea though, that off doing more, with less, appeals to me in both concept and practice, and living in an area where "Ski Chalets" are pushing 10,000 SF, I have a unique apprecation for the difference. The only thing we really miss is privacy when we have guests.
