Whatever happened to the Thames Lido?

I bought a slightly-out-of-date-and-therefore-really-cheap guide to the Thames a little while back, and found an intriguing entry for the Thames Lido, due to be completed in 2001. There was a precedent for such a floating pool: around 1875, a floating swimming bath was moored in the river at Charing Cross. It was a covered building containing a large pool with deep and shallow ends, changing cubicles, and even a bridge to dive from. The water was drawn from the Thames, filtered and heated. Admission was one shilling.

Obviously the lido never did appear, which is a real shame: it would have been an Olympic-size pool, 40 metres out into the river, which rose and fell with the tide. A clear covering was to offer swimmers all-round London views, and could close to protect them from bad weather. See the architects' image here.

So what went wrong? Unfortunately, it proved just too expensive - and so disappeared like so many British lidos. Instead, the current plan is for an ordinary indoor pool - as part of a controversial high-rise development.
