Hi Dr. I am looking to purchase a log home made with BC Red Cedar logs (square cut)which was built in 1972. The house is in great shape but is a little small. We are interested in adding an extention to this home. I was wondering if there is a rule of thumb as to the cost per sq. ft.? We are thinking about building up and out. What has your experiance been regarding this species of wood? We are located west on Montreal Quebec. Can you reccomend a builder in our area that could be trustworthy to
