The notched poles and bolts create a fast, simple and strong connection. They also strengthen the straw bale walls and help to create a beautiful wood framework. Standard engineering span tables are used to ensure safety. These are non-bearing walls that do not require much strength. They mostly serve to tie in the straw bale walls and add continuity to the design.
Trusses avoid the tedious and time consuming tasks of typical post and beam construction.
They can be built indoors, ahead of time during cold weather so many more homes can be built during mild weather. Trusses span from one exterior wall to the other so interior walls can be moved at any time. Footings and posts are not necessary in the middle of the home except for 2 columns that support the loft beam. Building trusses also create jobs during the coldest time of the year. Only a few tools are necessary.
