I'd like to thank Tim Walder, Steve Grindlay and the Sydenham Society for their hard work and expertise. It really is appreciated. The Louise Hse listing is a significant victory in its own right.

But how could the council not have been aware of the risk of Louise Hse being listed?
It seems clear from the posts here that the council in fact knew all about the risk, (this "privileged knowledge"), but ploughed ahead regardless with their grand scheme in the hope that English Heritage would not find out until too late. And they would have got away with it too, if they had demolished Louise Hse early as they had intended.

What a terrible picture this paints for the organisation that governs local planning matters. It is attempted planning permission evasion. What a rotten borough.

On the Forest Hill Society Vs Sydenham Society war, I think it a great shame and wasted energy. We need to move on, as the main battle starts now: with the council, to get them to honour their commitment to provide swimming facilities in the area.
