I'm working on getting ready to build a dedicated finishing room in my shop. I've got a roughly 16x9 area to work with. I'd like to end up with essentially a self-contained finishing room with space to a good size project (for example a book case or an entertainment center and space for fold-out drying racks when spraying smaller items like doors and drawer fronts. I'd also like to put a 5' run of cabinets in there that I use for mixing and storing finishing supplies equipment.
Floor will be wood (plywood or OSB), walls and ceiling probably drywall. The door would be a double door, 5' wide. Unfortunately its going to be about an 8" step up from the rest of my shop due to the joists for the floor. I can't excavate due to concerns with the "pit" filling with water during the wet season. Concrete would work but is out of the budget. I'll have a ramp outside the double doors to make moving things in and out easier. I'm debating on making the ramp long and removable or shorter and permanent. I really only anticipate needing it on the heaviest projects so I'll probably go the removable route.
I'd move my exhaust fan into here and build a new filter box over it. Fresh air would be drawn from my shop through a stack of filters in the wall.
Is this too much to expect from the space?
