When I first heard this mooted a few weeks ago, my immediate reaction was that I did not want the historic lands redeveloped. I felt that I would be in the minority & my initial minimal contacts with others seemed to bear this out.
However, after today’s press conference hosted by Boris Johnson it seems clear that the majority of local residents, & supporters from further afield are against the proposals. Some, no doubt, would be against any plans on principle & it would be well to try to avoid accusations of “nimbyism”. After all, if the Palace had not burnt down in 1936, it, like as not, would still be extant, possibly crumbling & almost certainly used for commercial purposes with all the attendant problems, but it would be the status quo & perhaps not many would have concerns.
Personally I like the old lands the way they are..in fact I kind of preferred them in the late 70s/early 80s when they were even less restored than currently &, in theory at least, were supposed to be not open to the public. In the long term, there is a huge tract of land, attractive to developers, standing idle & it can only be a matter of time before someone gains full permission to do something with it.
The current proposals need to be very carefully vetted for possible additional or alternative developments at a later date E.g. greater commercialisation or poorly designed housing. But a reconstruction of the old building, or something reasonably close to it, may be the lesser (least) of several other evils.
The alternative, possibly, would be to involve bodies such as The National Trust or English Heritage but I have no real knowledge of whether any conservation or preservation orders would be applicable. I believe some parts of the park are “Listed” but having recently taken part in the “Wiki Loves Monuments” project only the Sports Centre itself seemed to be included & “Grade 2” at that.
