I suggest you consider a two-pronged approach. By all means oppose the proposed use if you feel you can win that argument. I don't know the centre so cannot judge the strength of your case. However, you might wish to consider a fall-back position: that in the event that the Council is minded to approve the application, it imposes conditions. Yu have implied some conditions in your e-mail: - that the drop in use is for no more than n sessions per week - that the drop in sessions will be only scheduled for times when the history centre is not in use - that a joint liaison body is established to manage the potentially conflicting interests int he building and most importantly, I suggest...... - that any planning permission is for a period of 12 months only, after which time it will lapse. That way, if the co-existence works, it can be renewed. However, if it doesn't work, any apllication for a renewal can be opposed - not on the supposition of what MIGHT happen (the position you are in now) but on what HAS happened, if it is bad. I suggest you think as well about any improvements that you might welcome - extra security locks, CCTV, health and safety; that sort of thing. Hope this helps. Stephen Reid
