About Open House


Open House London first started in 1992. Back then our ethos was much the same as it is today. Giving free access to London’s best buildings was our founder Victoria Thornton’s way of inspiring the public about the benefits of great design. Our small team of staff deliver our programmes with the help of volunteers from across London, particularly from the built environment professions.


We are home to London’s most respected architectural education team – literally thousands of schoolchildren have participated in our annual programmes, we also run design awareness courses for community groups and host an annual sustainable cities conference for our expert professional audience. Much of what we do centres upon bringing city-makers - architects, developers, engineers, contractors – and the public together.


We believe the best cities arise when an informed and diverse public play an active role in shaping and maintaining the neighbourhoods they live in. We’re in this game for a very simple reason: because we love cities and we love London. And because we believe that great design - in architecture, urban design, planning and infrastructure - can transform the lives of ordinary people for the better.

One of my favourite events of the year, Open House offers the unparalleled opportunity to step inside the capital's most interesting buildings. The vast selection of buildings on offer span from the intimate to the paramount. This is a first class education in architecture, and it's free.
