Sept 21–22
Around 800 buildings across London will open to the public over this weekend, allowing access to many properties and spaces that are usually out of bounds to the general public. In addition to the openings, you will also be able to enjoy talks and tours. The list is officially published on August 20 but highlights this year – ballot places required (opens Aug 20) – include Downing Street, the BT Tower, the Shard, New Scotland Yard, Bloomberg European Headquarters and the US Embassy. Every London borough will take part.
