Post and truss construction is the simplest and may be the oldest style of construction. A simple box is made with posts fitted into the ground sills, although they may have been earth-fast originally. There are usually braces at the corners although they ma be replaced with “knees” to give more internal space. The posts are joined by tie-beams and wall plates and then the trusses are mounted on top.
The style of truss will vary with time and place. This design is distinguished from the box-frame by having one or no transverse members in the walls.
