For one weekend each year, doors into buildings and spaces that would usually be closed to the public, are opened. Visitors are invited to view and celebrate the diverse architecture of the cities in which they live.
Since 1992, Open House has taken place in cities around the world including London, Lisbon, New York and Helsinki. Celebrating its 20th anniversary with the theme The Changing Face of London, Open House London took place on the weekend of 22 – 23 September and drew approximately 250,000 visitors. They took the opportunity to reflect on how the city has changed in the past two decades, and how it will continue to change in the coming 20 years.
