Vote: what's your favourite building in London?

London is jam-packed with beautiful architecture, from the glittering glass spike of the Shard to the intricate masonry of Tower Bridge. And whether it's a famous landmark or an elegant building on our street, we all have somewhere we can't help but be enthralled by. In the run up to Open House Weekend (September 20-21) we're asking you to vote for your favourite building in the city. We'll announce the winner that weekend.

Plus, one lucky voter will receive two queue-jump passes, allowing them to whizz straight to the top of the Gherkin at any time over Open House Weekend, plus a copy of the Open House London Book and Guide to Contemporary Architecture. Vote now!
