Thanks, if you look below the forge you can see that blocks stick out of the wall at that point, from the ground up to the hatch, so I had to build that stainless heat shield at the back of the forge around them. Im not really sure why the wall is designed like that , its not like that on the opposide side of the building. Must be something to do with the hatch. The man that built the shed put the hatch there as he used that part of the shed for storing peat. He would back a truck up to the hatch when the shed was getting full and start filling it from there instead.
More recently my sister used it as a stable for her horse as you can see by the stable door, up until a few years ago. Now I use it as my shop
