I missed the fork, so re-posting this here with some extra:

Also put brazing and furnace work with these. Flammable, able to produce

But will produce swarf, chips, leave oil & grease residues on nearby
surfaces, coolent/lubricant spray.

A simple spray-booth can be made from one of those greenhouse tents.
Also cheap enough to replace say once a year (especially at the end of
growing season).

I'd also add "textiles & crafts" which'd also need a clean area.
While we can't be too specific without at least a map of the area, the
main issue I see is ventilation verses "offence to the senses".
Welding, grinding, brazing, casting, painting, etc.. all need good
active ventilation, which gives it a priority of being upstairs near the
big rear doors. They're also the dirtiest, so you'd think they should be
prioritised near the bathroom with shower, rather than have filth
trampled through the space.
However they're also noisy and not particularly inviting to look at
(even dangerous), and if we want more members we need the upstairs to
feel inviting. Ideally we also don't want to annoy the upstairs
neighbours with excess noise and save us any future landlord issues.
Having a welcoming environment coexist on the same floor as these
processes is tricky, but I think it can be done if we compartmentalise
off around the rear door. Say leave enough reserved space to get a small
vehicle or rear portion of a van into the workshop (because someone will
want to do car repairs now they can, or unload out of rain). Say 3-4
meters? Then have a partition wall with courtesy windows for the
curious. Grinder noise is the only issue. I doubt proper soundproofing
will be economical, but some curtains over the wall may suffice for any
night-work. Simply opening the doors during day-work will decrease sound
internally. Grinding does seem to be done in sessions, so isn't a
*continual* noise issue.
So have a reserved work area large enough for a SMALL vehicle with the
metalworking tool stations along one side and the bathroom the other.
Perhaps even a short "porch" for it, for hanging coats/boilersuits and
further limit cross-contamination by dirt/sound/scent.
With metalworking cordoned off, the majority of the rest of the upstairs
gets to be social (making use of countertop area and mini-kitchen).
I'd put drills, woodworking, rage-saw and lathes/3-in-1 downstairs,
again partitioned off from cleaner crafts work & laser cutter, and again
from electronics in another partition but sharing a ventilation conduit.
And doormats everywhere so people wipe their feet between areas.
I don't think it'd break up the sense of space TOO much.

Oooh, drying space. Good thinking! I wonder, would it be safe/advisable
to use the utility room for this? The machinery in there must surely
make it warm and good for drying.

A clean room would be the perfect place for the vacuum-station. It will
be a lot more reliable in such a place.

See above suggestions. Just buy a cheap "collapsible" greenhouse. Won't
fit more than a bike-frame in it, but can just get a bigger one later.

Grinding is the big issue. It's a very (hurr-hurr) abrasive noise.
However I think a solid wall should muffle it enough to make it's
occasional use tolerable.

Shipping container was also suggested for bio-hacking. While we have the
space for a few in the car-park, remember they're usually delivered by
truck & possibly crane for larger ones. The rear road access dimensions
will determine what sizes are feasible.

I say keep it. Put a little lobby around it with a couple of coat-hooks,
it can serve as a dirt airlock from the metalworking area (if placed by
the door) where you can wash your hair free of iron filings before
taking the train home. It'll be a godsend after a day of either metal or
woodwork.
Just make sure it has an "occupied" timer on the door, play an alarm at
20/30min use so no one plays silly buggers with it.

It's probably bikeshedding, but I still love the idea of networked
speakers & cameras for that Aperture Science vibe. Each area has a
camera and a speaker. CCTV like currently, but expand doorbot for
space-wide status warnings like telephone, smoke, welder-in-use, maybe
text-to-speech from logged in users viewing cams on the website (with
user ID of course). And with virtual terminals, let them act as speakers
for different music in each discrete area.

I like the clean-room idea. Yes ventilation, but not as excessive as the
metalworkings. I'd say have a small ducted system shared by this, the
etch-tank and soldering areas, all of which are supposed to be basically
"clean".
Yes I know the etch-tank is a mess and a messy thing, but it *shouldn't* be.
