Open House London - free tickets to the greatest views in the capital
Poking around buildings we shouldn't be in is always good fun, whether you're an urban explorer or in need of a venue for your extra-curricular yankee doodle. It can also make for a dirt cheap birthday present too, especially if you can enjoy on once-in-a-lifetime views.
If somebody you know has a birthday in September, you could do a lot worse than apply for free tickets for Open House London, when buildings across the capital will open their doors to the public for two days only. Kensington Palace, the London Eye, London Underground Head Office, The Royal Society - there are tickets to every shape and sort of building. There's also one venue that'll be in huge demand - BT Tower.
The observation deck and restaurant haven't been open on a regular basis for three decades, but on Sunday 19th September the 34th floor will be open - for just five and a half hours. Tickets are free, but only available through a draw, with each successful applicant receiving a pair of tickets.
