This might be a difficult thing to find in Zürich - believe me - I tried for ages to find a workshop there and the prices were outrageous and many potential rooms not permitted for that purpose (noise
But I found another solution : I have a large workshop with some interesting tools in Flums - right at the bottom of the hill up to Flumserberg. Great for a bit of building first thing, then a bit of skiing while the glue dries, then doing the finishing late afternoon or evening. It's over 100m2 with 380v power and a cargo lift to get there. I used it to build skis and snowboards - then test them out just up the hill. It's also running 100% off hydro power generated onsite - super green !
I've got a bandsaw, pillar drill, compressor, overhead belt sander, ski & snowboard service machine, various hand tools - drills, angle grinder, orbital sanders, router, thickness planer, tons of clamps, plus one huge one for wood lamination (for making panels from strips or planks of wood) and many other goodies.
I'm considering ending my tenancy there due to relocation, and if a group of makers were interested in taking it over then we could look into that.
I could propose a couple of options :
a) I'd be willing to sell the whole machine inventory at a super low price and hand over tenancy lock-stock to a group who'd be interested in taking over. This would involve a startup cost from your group to take over my refundable rental deposit and buy the tools at a low one-off cost.
b) I'd be willing to start a 'maker club' and then sublet usage of the room and tools to individuals who want to use the facility themselves and they'd pay me a monthly membership fee to cover my costs - rental and insurance. We'd also put a portion of the fee towards machine upgrades and consumables to make it sustainable.
Flums is about 40-60 minutes from Zürich, and the room is on the 5th floor of a lovely old mill with lots of other interesting tenants. Waste disposal onsite included too for all your scrap and waste. The one restriction in the room is welding : I don't need to do that, but they asked specifically as the place has automatic fire detection and welding smoke would probably trigger the Feuerwehr to pay a visit ! For limited welding I'm sure they'd provide a solution as there are other shared spaces and sheltered outdoor areas downstairs which would be suitable.
