We built the walls and framed the roof this weekend. It has been hard to find time for this project, but we finally have everything finished except the roof. For the exterior finish we used LP Smart Siding. This type of smart siding looks a lot like T.1-11, but is constructed from Advantech, which is a much stronger. Also, smart siding comes with a factory primer already installed, saving us a step in the finishing process! You can learn more about this product from their website www.lpcorp.com
