This is too much storage, probably. The floor plan already looks/feels crowded. I can see a certain judicious amount of inside-woodshop storage, maybe for vertical storage or special/class projects or storing sleds and jigs neatly, but once any space is allocated for members storage and gets used up and becomes the status quo, it will never be able to be recovered for other uses (or at least not easily).
I’d rather see general project storage outside the wood shop used for this, or nearby offsite solutions (e.g. right across the highway) urged. This solution has already worked for a group or two of folks.
