The latest building with a nickname, the Walkie Talkie, is topped out

Midwinter sun makes a rare appearance during the week that the latest London tower with a humorous nickname was topped out. Formally known as 20 Fenchurch Street, the distinctively bulbous 'Walkie Talkie' has been designed by Rafael Viñoly and is due to be completed in 2014. Due to be topped by a 'skygarden' - London's highest public park - the skyscraper is being developed by Land Securities in joint venture with Canary Wharf Group.
