I've finally got onto the gas company to arrange a site visit so they can give me the estimate for relocate my gas meter. That took about two and a half weeks!
Now I have to wait for the distributor to call me for the appointment. We'll see how long that takes!
In the meantime, this week I had a play with modelling the garage. While I was out measuring, she-who-shall-be-obeyed observed that it would make more sense, if I am "going to build this thing", to encroach and extra 1m into her garden to give me more space inside. God I love her!
Gives me about 4m width, and 5.4m length. Biggest issue is that I will have to use the side door, so may need to use smarty-pants trolleys like a GoJack or similar.
Here is a couple of 3D images of the plan....
