Our house inside our greenhouse!
New member here (hope photo posts OK).Constructed (used, bought off craigslist) 30'x60' clearspan aluminum framed glass greenhouse over top of our 400 sq. ft. cordword cabin. Unheated at this point, greenhouse came through ~100" snow, -10 temps., winds up to 40 mph this winter in great shape! Ecoblock foundation & buried 500 gallon water tank helps stabilize temps, but single pane glass just sucks the heat out. Over 400 panes installed & only broke one (never glazed before=you learn quickly to be very methodical). Someone told me you have to dream big to achieve big - and we did it!
