Blimey. Hopefully the very worst of the winter will be over by then, and you'll be set up really well for the coming year.
I was wondering where you were doing the work, everyone on tv always talks about being loaned the space by a friend, etc. Works CP is at least free, I suppose - sorry to hear it aggravates the arthritis some bits of ageing just creep up and won't go away
Homes and Retreats
We are waiting for more details and photos. So far looks good. I think you have to watch some youtube tutorial videos, I saw similar projects being done there. I saw Munich homes https://tranio.com/germany/bavaria/munich/detached/ similar to the project you have. Good luck anyway!
