I've been investigating moving my office from Zürich to Zug - or maybe putting it temporarily into storage. I asked the removals company whether they could store the items - the one I was dealing with did. They have a surprisingly large warehouse in Affoltern am Albis.
They have pictures and details (albeit in German) here:

Not that I'm scheduled for kickbacks or anything, but if you DO end up over there - tell them *that American guy from Sattel* sent you. I'm about to have them move my office... maybe it'll help.
They moved me out of Affoltern to Schwyz - they did a pretty good job. They could also move your stuff from Zürich to Affoltern for the duration.
...maybe I *should* investigate that kick-back thing...
