Nicely done Martin.
All of it.
I know mostly, the guys elsewhere in the world have loads more space to build, while your space is incredibly limited and often clever photography makes it look much bigger than it is.
One needs to keep in mind, you are totally solo in your build, except when you need extra muscle or even just an extra hand to safely attach or remove items when you are able to get someone to come to your place. At 15 miles, people like Steve and I are the closest help you have. Your challenges are pretty real here in England.
You have certainly moved the mountain here.
Well done !!
