Hi Jim, that's a good question. I try to put my thoughts into words. The higher work surface is 1.1 meters and is intended to serve as a planning and construction area, 1.1 m for the reason of being able to work while standing, which is easy on the back. The other height is still 0.95 m and will be a kind of desk, the narrower side is the machine area, where my small milling machine can be found and later the second, slightly larger one. The lathe is placed on the far right in order to have a better view of the working tools, the lower height. I hope I was able to explain it clearly.
