Another question is "why balsawood"... it's great for certain things, like flooring, furniture, support rafters, etc., but if you are doing a wooden building, I suggest Balsa FOAM.... sold in sheets of varying size, and easy as chalk to carve. I have done several buildings that simulate both wood, mortar, AND brick out of the same piece... and the stuff is very cheap (and of course, availalbe on my website!)
