How to Get Involved

Register your building

Would you like to showcase your building in London’s biggest architecture festival? We are looking for submissions of award-winning projects and other examples of architectural excellence.

We start building recruitment in Feb 2020.

** Due to the Covid-19 situation the deadline for building proposals has been extended to July 2020**

Volunteer at a building during the Open House weekend. Our volunteer programme is one of the largest and most respected of its kind and is core to our working philosophy.

As a volunteer you will be helping building owners/representatives to open their buildings to the public. In a lot of cases, the buildings would not be able to open without volunteer support. You only have to commit one morning or afternoon on one day during the event, and you will be able to choose a slot from a list of buildings which have requested support.

Protect Open House from Covid-19 

Open House has been hit hard by Covid-19. After three decades of keeping the festival free for all, we are asking those who can afford it, to help us through the pandemic with a small monthly donation by becoming an Open House Friend. We are creating some great rewards to say thank you too.

The Open House is one of my favorite weekends in London; I always learn so much and am left with an even longer list to attempt the following year!

It cemented in my mind how wonderful and intriguing a city London is and how many hidden stories lie in plain sight down every street.

As always, totally fascinating (if exhausting)!
