Very nice large shop - you could not go that big in Calgary. My garage is max without special development permit -i.e. 800 sqft.
Need to add some more heavy iron to your setup - you have plenty of space!
I'm "sort of" maxed out now. It's based on a percentage of your property area (10%). I could have gone to THE max of 2100 (vs my 1650), but then the new stupid foundation laws they imposed would have kicked in. Anything over (I want to say 1073) means the foundation cost would have almost doubled (!) as the footers get huge, deeper, etc. -- and it was a HUGE bill already!! Just to get to the "parking pad" phase ended up being just over $20K. That does include the engineers drawings for the building, the excavation, forming, etc.
Main regrets now are going long and narrow. I should have made the whole place an "L", so the addition was more of a square than a rectangle. And the second one was where I positioned the hoist (at least I can (gag) change that!). Should have been 20ft closer to the other end.
Oh, and as for more machinery.... ummm... Still have my blast cabinet to move in (I'll show that later), and MUCH more shuffling to do. It's already getting tight in there. I really don't have much space left!
