Believe me Mike, you've got loads of space!
Your proposed shop is pretty well the same size and dimensions as mine - and I manage to run a pro cabinetmaking business from it with myself and two staff.
As Scrit says, you need to consider the flow from timber store to finished goods and arrange your machines accordingly.
Personally, I prefer to have the big machines for timber preparation grouped together towards one end of the shop near the timber storage area. I would then have my main work bench and smaller machines such as router table, drill press, morticer, and chop saw towards the other end. I find that this arrangement means less walking around!
I would definitely partition off a small dust-free area for finishing with a stud wall and door. It is vital for this area to have a good sized window in it for natural light as well as ventilation.
Your timber storage appears to consist of upright dividers. This is fine for short-term storage of sheet materials but solid timber really needs to be stored flat. Have you any space for a timber store in the eaves? It'll be nice & warm up there!
Good luck with the project and I look forward to your updates (and opening party?)
Cheers
Brad
