The next 10 in our series:

Oxo Tower | Sunshine colourway: Located on Southbank, the OXO Tower was built in the 1930s. Today it is home to cute galleries, shops, cafes and restaurants.

Millennium bridge | Jewel colourway: Opened in 2000, this steel suspension pedestrianised bridge was then closed temporarily due to heavy footfall causing a swaying motion. It then reopened in 2002. A collaboration between Foster + Partners, Sir Anthony Caro & Arup it links St Paul's / City of London with Bankside. Here's a great write-up on the project.

Piccadilly Circus | Sunshine colourway: Built in 1819 to join Regent St with Piccadilly, Piccadilly Circus is a hustling and bustling part of London. The famous lit up advertising signs started in 1906, but now only covers the one building here - on the corner of Shaftesbury Avenue and Glasshouse Street.

Royal Exchange | Earthy colourway: With an incredible history dating back to 1566 as a stock exchange, today The Royal Exchange is filled with boutiques and restaurants. Destroyed by fire twice (including the Great Fire of London 1666), today's building was designed by Sir William Tite in 1844.

Trellick Tower | Exotic colourway: Designed by Ernö Goldfinger in the late 1960s, Trellick Tower in Kensal Green is one of London's most famous examples of Brutalist architecture. It became a Grade II listed building in the late 1990s.
