These timber frame king post truss plans can be used for the roof trusses in your great room or master bedroom. It is one of the simplest form of truss in that it is constructed of the fewest number of timbered members other than the common truss. The truss consists of two diagonal members call struts, one horizontal beam that serves to tie the bottom end of the two rafters together, and the king post which connects the peak to the horizontal beam below.

This instant-download PDF  package of 11 pages of drawings, materials lists and renderings makes this a fantastic project for any DIY craftsman who wants to learn about timber frame construction techniques from the ground up. Whether you rest this truss on conventionally framed walls or incorporate a timbered post to the truss, it will surely add to your space.

The width of the plan is measured from outside edge of rafter to outside edge of rafter.
