Following on from this earlier post about the groundwork, here comes a post about the foundation and main wood frame construction on our reciprocal roofed roundhouse. We put down a layer of builders sand all over the floor area and raked it out until it was even. On top of this we placed a waterproof membrane. At the eight posts we added extra pieces of membrane between the concrete foundations and the posts.
We moved into our cottage in January 2013. Even before we bought it, we had decided that we would add a round house extension to it, with a reciprocal roof. These types of houses have been built for thousands of years, mainly in China and Japan. It is a very economical and environmentally sound way of building, and can be adapted to suit many climates and site conditions. We would like to share our experience of the build with our readers here, in case someone would like to embark on a similar project.
