Roof trusses — Why not whole-house trusses?
I saw the picture of the attic room roof truss in this recent discussion https://www.greenbuildingadvisor.com/community/forum/energy-efficiency-and-durability/39005/basic-beginner-air-sealing-questions and was also recently looking at double stud and Larsen truss building methods and it struck me, why not incorporate the roof truss into the double stud wall so that the house is assembled just like a roof is?
Fast, Structurally superior to “stick” built house with proper racking considerations, Integral energy heel and structural thick walls with minimal material and fuss.
Rectangular-ish houses only, Transport issues with large trusses, probably single story or top story only unless the whole system is modular with non-roof first floor members. . Unlikely to be raised by hand, but most large trusses aren’t anyways.Still needs fireblocking. Window and Door installation requires additional thought.
