TW Builds a Garden Room

Amazing job! This is what I want to do this spring/summer! Couple of questions:

1. What are the dimensions on each "room"? I have the same idea of an office + trainer and then shed + storage. Happy for you to just send plans if easier
   
2. For someone with a terraced house, do you think it would be possible to have some of the long lenghts of timber split in two and joined with the metal bits in between and nailed together? Alternatively my retired neighbour has side access that I could use but wouldn't want to bother him everytime I have a different delivery
   
   

Planning on basing a lot of my build on the Oakwood garden room build pack
