Okay you’re asking yourself, why on earth would anyone need to know this? The answer is, I don’t know, but you might as well read on.
There are a lot of experts out there with opinions but nobody I asked could give me a definite answer. The closest answer I got was from Matt Murphy of Admiral Building Movers who said that for a wood frame building it depends on the foundation size (the footprint) and the number of stories. As his business is building moving, shoring and jacking, he figures weight without foundation and garage spaces and said that if the house interior includes sheetrock and heavy flooring the weight doubles. So I contacted a number of architects, builders and engineers and based on a blending of all the answers I got here’s what your house might weigh (including full interior, foundation and garage):
Average 1 Story Ranch 24’x36′ footprint (864sf) … between 52 and 86 tons (this one would take between 600 and 1000 people to lift it)
Large 1 Story Ranch 28’x40′ footprint (1120sf) … between 68 and 112 tons (this one would take between 775 and 1275 people to lift it)
Average 1.5 Story Cape 28’x36′ footprint (1512sf) … between 69 and 139 tons (this one would take between 700 and 1600 people to lift it)
Large 1.5 Story Cape 28’x60′ footprint (2520sf) … between 102 and 231 tons (this one would take between 1160 and 2640 people to lift it)
Average 2 Story Colonial 24’x36′ footprint (1728sf) … between 86 and 119 tons (this one would take between 1000 and 1400 people to lift it)
Mid-Sized 2 Story Colonial 28’x40′ footprint (2240sf) … between 112 and 154 tons (this one would take between 1300 and 1800 people to lift it)
Large 2 Story Colonial 30’x60′ footprint (3600sf) … between 180 and 248 tons (this one would take between 2050 and 2850 people to lift it)
Estate Size 2 Story Colonial 48’x90′ footprint (8640sf) … between 425 and 600 tons (this one would take between 5000 and 6800 people to lift it)
Estate Size 3 Story Colonial 48’x90′ footprint (12960sf) … between 594 and 756 tons (this one would take between 6800 and 8800 people to lift it)
For extreme contrast, there actually was a house designed by a very famous inventor/thinker, named Buckminster Fuller (he’s famous for his geodesic domes) in the 1920’s called the Dymaxion House which among many other design considerations was designed to minimize its weight. The final design was a 1 Story Circular Ranch style that had a footprint of (1100sf) and weighed just 1.5 tons (this one would take just 18 people to lift it).
