20 Fenchurch St, London
20 Fenchurch St by Architect Rafael Viñoly. Also known as "The Walkie-Talkie", is a 160m tall commercial building. It won the Carbuncle Cup in 2015 but I found it really nice. It was noticed that the winds at the bottom are too strong and the sun beams reflected used to burn cars. It has an sky-garden on top and an amazing view over London.
