Hi I need to build a 12 x 12 stable for my daughters pony. I'm guessing a 3 x 2 framework then clad in t & g outside and then the bottom half inside lined in a thick marine ply board. Question really is what is the best fixings to join the frame together solidly?, I'm going to put it on skids to bypass planning so it needs to be able to be pulled around and sit on wet slabs without rotting.
