Church halls are good reference points for participatoriums.
They can be home to lots of rule sets - for table tennis clubs and band nights, campaign meetings and Cubs.
Governed by overall rules of civility - stack the chairs and do the washing up when you are finished.
They are one big room.
But it can be reconfigured - for band night put the amps at one end, for a jumble sale put the trestle tables round the edges, for a film screening put the chairs in rows.
There is common investment and ownership, with negotiation and compromise over use.
They are landmarks, and membership is open to everyone who lives round here.
