(Sherwood - I'm glad you don't think immigration is a problem. I did not call you a racist, but I apologise if I misread your views.)
In reply to BD,
The point you make is interesting; A desire for a clearly structured and planned urban environment, giving a sense of overall coherency - I wouldn't argue with that at all.
But I also think there needs to be a certain ammount of scope for the individual to improve, extend, infill and re-build. And I think this applies to homogenous Georgian Squares (see example below) as well as 1930's streets. But there are provisos here - the architecture must be exceptional, and other people must not actually suffer (loss of light, privacy etc - not just 'I think it's too big/not in keeping/too modern/too dense'). There is something to be said for eclecticism - the Walter Segal (method) houses in SE23 for example; http://www.themodernhouse.net/docs/intro...d=0:155:28
An examples of really good castle building;
