Sooooo..making the most of a bad situation. The back yard dividing wall is about 1.7m high with no capping stones and the back wall is about 2m high with old pointed capping stones on it. If I just shove the base into the corner where these walls join and build 2 walls and a roof from plywood should I use 12mm or 18mm plywood for the walls?
Any other advice gratefully received.
Thanks.
