Why the 4x4s are protruding: The 4x4s are part of the floor support for the second story of the house. We purposefully designed then to protrude from the house. This is not some kind of adobe stick roof design throwback attempt but rather a structural idea. By leaving the 4x4s extended we will be able to tie our roofing beams into them. We will through bolt the beams and the 4x4s thus creating a fully connected house. This could either make the house a stalwartly solid unit or be a terrible idea the causes the house, particularly the floor, to creek when the wind blow agains the porch roof.
