Has anyone seen a type of construction with 14" alternating plank walls on the interior walls? We just bought a 1850 or earlier farmhouse. Exterior is stone, interior is all this board on board underneath the plaster. No traditional wall framing. The boards are secured directly to the beams of the house. Any information on how and if these walls are load bearing and how you worked with them would be appreciated. I have pictures but I can't post them for some reason. Thanks!
