This house is across the road from the house where I live. It is one of three houses on my family Ridge Ranch. It was built approximately in the 1860's, probably after the Civil war. This was estimated when the couple who live there moved in about 1972 and in the process removed newspapers that had been tacked to the walls for insulation. Some of the interior boards are old growth redwood more than 2 inches thick and almost two feet wide. Give the cost of Redwood these days . . . that is amazing.
