Ballots & Bookings

There are a few cases where bookings are required to be made in advance. However, in line with the original Open House London ethos of providing access to all, no bookings are administered by us. Contact details for relevant buildings will be provided in the published guide as well as online.

Ballots are operated in a small number of instances. Information will be published in mid-August on publication of the guide. Please note the ballots are open for a set period of time, and are NOT operated on a first come, first served basis.
