Build a Log cabin has several steps. you first design the log cabin. When drawing up log cabin plans, first determine the outer dimensions. Next find a site for cabin and prepare the ground and then Prepare logs by removing the bark, branches and knots. Also cut and shape the ends of the logs. Dig the postholes. These should be fairly deep, but be aware of the frost line. Next install the log posts in your holes. Set them in place with reinforced concrete. Set up the main floor beams and joists. Use plywood or nice wooden panels for the floor. Cut notches that will hold the logs together, and shape the sides of the logs so that they fit as snugly as possible against each other. Leave spaces in your log cabin for the door and windows. And then set the loft supports by fitting them into the walls or by running logs into additional holes cut in the wall logs. These logs cross the interior at ceiling height and can support a second story. Next build up the gables one side at a time until you reach purling height. Purling are structural supports that cross the loft space. Continue building up the gables until you get to the height of the ridge pole-the main centre roof support. Frame out the roof using prepared lumber. Be certain everything is level and fits snugly. Use plywood as the underside of the roof and install tin sheeting over it. Purchase used tin sheeting at a discount from military surplus suppliers and lumber yards. Install other components, depending on your log cabin plans. Log cabin kits will include these other sections, such as windows, a chimney, stairs and other essential components of log cabins. Finally personalize your log cabin with such touches as a wood burning stove, wall carpets or hunting trophies.
