Roof fans and vents might be an option - or replace some of the panels in or the entire roll-up door with a bit "louvers" setup for the intake venting.
Those are some awesome ideas definitely going to have to look into it! My construction guy did say "Don't worry about it, we'll just vent everything up, I'll knock however many holes you want in that ceiling"
Sadly I STILL haven't been able to meet up with the landlord, my agent is telling me not to worry it's just a conflict in our schedules, but still, I just want to check it out, secure the location and start the process - setting up internet alone takes 3 weeks + here so I'll be running off hotspots in the mean time.
