UPDATE: The Chair of Lambeth Planning, Cllr Toren Smith, has left me a comment on Facebook:
That is the Strata tower on the site of Castle House at the top end of Walworth Road at the Elephant and Castle. Its in Southwark. Its a residential tower and the tallest in south London until the Shard comes along.
Thanks Toz!
Taken on 1 October, although an evening out of course meant I could not upload it until today
This was taken on Horseferry Road, not far from my office, looking towards the roundabout that marks the approach to Lambeth Bridge over the River Thames. This large building is growing rapidly and is visible from various locations.
BUT I DON'T KNOW WHAT IT IS!
(here's where I'm hoping someone in Blogland can help me!)
