I'm a member of Cambridge Makespace (where I live) and London Hackspace (where I used to live). Both spaces are fairly mature and have a reasonable number of members for their available space. At a Makespace new member induction each new member is told that they may have a Really Useful 35L box to store items in (less solvents/flammables). This works really well as they are cheap (~£13), robust and store quite a lot of stuff. We have shelving units in our corridors which take ~15 of these boxes so storing the 200 odd boxes doesn't take up too much room.

However we now have enough members that problems with the system are beginning to show. These seem to be: claiming of permanent workstations, excessive personal storage and large item storage. The first two problems largely seem to be solved with tellings off, we've not progressed to formal disciplinary actions yet. We're currently working on using some unused underfloor 'rooms' as large project sto
