Open House London is opening the doors of some of the capital’s most famous and exciting architecture. For one weekend only, over 800 buildings, neighbourhood walks and architects talks will be taking place across the capital’s landscape. What’s more, the tours are completely free, so why not view London from within the famous landmarks themselves. This is a unique opportunity to view the 6 storey-high Canary Wharf Crossrail site ahead of station completion in 2018. Catch it before it changes forever. This event is free and entry is on a first come first served basis, so it can't be guaranteed. We need your card details to store the event information in your profile, but rest assured, we won't charge you a penny. The walk is self-guided using segregated walkways. Sensible clothing, jeans and closed-toed shoes are advised. It is unsuitable for under 5s. Last entry 4pm.
