My Grandfather had built a cabin just like this in the 1930's. When we tore it down in 1997 I reversed engineered it and had drawn up these plans to reproduce the cabin at another lake. These drawings are of a modern version of the old cabin. These are modern drawings produced using AutoCAD software to ensure accuracy. Build it yourself!

After over 30 years in the Construction industry he developed a passion for building cool items around his farm and cabin. These are great DIY projects.
