I'm probably causing some controversy here, as it has been voted one of Britain's worst architectural eyesores, but thousands of people can be wrong.
A little history for you: No.1 Croydon (formerly the Noble Lowndes Annuities or NLA Tower) sits right at the centre of Croydon, opposite East Croydon train station. It was designed by R. Seifert & Partners and completed in 1970. It has 24 stories and at 269 feet (82 m) high is Britain's 88th tallest tower. If someone was to convert this into flats, I'd be first in the queue (can you imagine? A lift at the centre, leading to each of the pentagon shaped flats? Genius.) Unfortunately, it is actually office space occupied by AIG (their UK headquarters), Directline Holidays, Pegasus and other companies.
The building was refurbished in 2007 including a cleaning of the exterior to rid the smog caused greyness and reveal a gleaming white. As it gets dark, it takes on a new feel - a multicoloured light display illuminates the building as people make their way home or are going out on the tiles.
And why do I like it so much? Ugly? Well, kinda - but it depends how you look at it. You can imagine this being the sign of the 'up-and coming commuter town', towering over the Borough. A time when a concrete tower was state of the art and an exciting sign of modernity. I love that, as it's nickname suggests, it really does look like a stack of 50p's left by a giant. It's a unique design, love it or hate it. I like seeing it on the horizon as I commute back from work, so I know I'm nearly home.
Whilst I do love the Gherkin, Battersea Power Station, and of course, the Eye, I'm happy for those to be everyone's favourites of landmarks of London, whilst the 50p building, is just one of mine.
(many thanks to the Wikipedia entry that educated me so much about this great building)
