About Open House London

The capital's greatest architectural showcase takes place every September with a wide range of events and tours taking place across all 33 London boroughs. This established date in London's cultural calendar is a truly citywide celebration of the buildings, places and neighbourhoods where we live, work and play, and the value of good design in creating and sustaining a vibrant city. It is a unique opportunity to get inside what makes London great and be inspired by the power of architecture to transform the quality of our lives, with hundreds of buildings of all kinds opening their doors, plus neighbourhood walks, cycle tours, talks and debates taking place.

Open House London tells the story of amazing architecture in every London neighbourhood. Londoners find out more about issues that are relevant to their local area - from the design of homes to the impact of climate change, and the role of architects and contemporary design in revitalising places.
