Open House London, the capital's greatest architectural showcase, takes place this weekend, 18 & 19 September 2010.The initiative is a simple but powerful concept: hundreds of great buildings of all types and periods open up their doors to all, completely for FREE. It is a truly city-wide celebration of the buildings, places and neighbourhoods where we live, work and play, and is your opportunity to get out and get under the skin of London's amazing architecture.
