Serpentine Desecration

This is a picture of the new view from the Serpentine Lido in Hyde Park.

I assume that this ugly monstrosity being built has something to do with the upcoming olympic games. I can't understand how they can square this with the idea of the park being a public space. (N.B. this is not in the Kensington Gardens section of the park which, being a Royal Park, we, the public, are given kind dispensation to use by the monarch.) My objections are: this totally spoils the view across the lake, and when the events that these stands are set up to view are taking place, the stands will not available to members of the public. I suspect they will be used to make money for the organisers or to bring glory to the hideous sponsors.
