We have a very large barn that was built in the late 19th century. It is getting very rickety and we have the means neither to fix it nor tear it down. We thought of selling it, but have no idea of how to go about it. The beams are hand-hewn; the fact that they have suffered powder post beetle adds to their appearance (tho of course anyone would want to fumigate them before using them for decoration as a mantle, etc.) There is a lot of wood, as the barn is the height of a two-story building basement to roof. Any ideas?
