Hi ohdearme From your description you are fitting additional bearers to the ones which come with the floor. It is worth making the additional ones the same length as the shed floor and then fitting a skirt at the bottom of the sides to protect all bearers. Leave the skirt with a gap to your concrete base for ventilation but fit a wire mesh to keep rodents out. Regards S
Actually Stoneyboy I am making the whole thing, so there are no existing bearers. To clarify, the floor sits on the bearers with no overhang, but "skirt"? Does that mean wrap the dpc around the bearers somehow? Please explain and thanks for your help. Alan
