I agree with chica and others that relocation to Willow Way is really a very bad idea indeed - that area doesn't need another pool (they're already got Bridge). In reality, it amounts to most of us losing convenient access to a pool altogether.

In my opinion, there are a few issues with the current proposal:

ASSESSMENT CRITERIA:
I do wonder whether there is scope to reassess the criteria the Council is using? I am under the impression that they have not been especially well-thought-through... similar to the entire pool planning process to date, unfortunately.

I believe that the criteria could be improved to more properly value: (i) greatest benefit for the greatest number of underserved residents; (ii) ease and enjoyment of use once built; (iii) affordability; and (iv) aesthetics. The last criterion may appear to resonate with the conservationists; however, it is not necessarily an argument for preserving the frontage. Whilst I think the frontage is beautiful and complements the general feel of the area, I am sufficiently pragmatic / open-minded to recognise that it may not necessarily be the optimal way to deliver the above criteria. Which brings me onto the next issue...

DESIGN
I believe that all of the current designs, and the proposals of which they each form a part, are flawed in one way or another. That is not to say that the architects are necessarily to blame; rather, it is more likely the outcome of poor briefing - itself the result of poor planning and scoping by the Council. Whilst I believe that it would be regrettable to delay the process (in essence, depriving everyone of a pool for even longer), it is arguably an even bigger mistake to build something shoddy / ugly / unworkable / etc. (see Forest Hill train station!)

Although I am a relative newcomer to the area, I get the impression that the general feeling about Forest Hill in particular is that it's got some lovely houses and areas, but that there's not much going on and the central area could do with some sprucing up. It would be a mistake, therefore, to build something that looks fairly cheap and is completely discordant with the feel of the surrounding residential areas. As such, I think it would be best to at the very least revise the current designs, but more preferably to come up with some new designs.

WILLOW WAY
In this instance, I think the Council has lost sight of what's really important. The main point is that (central) Forest Hill needs some pools. In trying also to kill two birds with one stone, by tying in the Willow Way employment zoning issue, we risk doing everything poorly. Expediency seems attractive, but as we've seen from the current proposals has yielded universally dissatisfactory outcomes.

Willow Way can quite easily be figured out on its own - perhaps a multi-use development to provide more housing and also fulfill the employment zone objective? Certain kinds of shops could fill a local need and also provide a lot more employment opportunities than a leisure centre would.

In summary, it would be best to untangle the issues, and approach each one separately - sort out the Forest Hill pools on the CURRENT SITE, and sort out Willow Way on its own. That is not to say that Willow Way could not subsidise the pools, but I can't imagine that the current proposals are even close to best for each site.
