After watching "most" of the video and reading comments here, I have mixed feeling about the shop.
I do find it odd that an architect who in his profession has to consider access and egress standards did what he did! That said; it is his personal workshop, play pen, and works for him.
The critical comments here are points to ponder, while his shop works for him, that doesn't make it right. I see some interesting things that are good ideas poorly executed, I see things that I just don't get and, things that are flat out bad choices. Again, his shop works for him, based on feedback here it wouldn't work so well for many others.
The luxury of space becomes moot when you fill your open space with idle stuff, the too good to pass up deals that clutter his shop are a classic problem. I see this with guys that get into hobby's, they go wild buying every "good deal" they find, regardless of merit or need. It is fun to collect the machines and tools you dreamed about. There is no harm in that but, when it inhibits the use of your shop, you have been elevated to hoarder!
With all that said, I wish him well and hope he enjoys the time he spends in there. Nearly all of us have to make compromises in our shops, he has made the most of what he has for his particular needs.
