To a Londoner who doesn't go back there much the amount of recent development on the South Bank opposite Victoria, Chelsea and Fulham is very noticeable.
There are some photos of the construction of the Tower at St Georges Wharf on the link below which show its size
One St George Wharf (The Tower) | Lambeth | 181m | 49 fl | T/O - Page 119 - SkyscraperCity
If you 'walk' across Vauxhall Bridge in Google Earth Streetview the new tower and crane pop in and out of existence in the sequential views....Battersea power station which is much closer to the Heliport (and pre-dates it) can be seen in the background
