The vast majority of buildings are on a first come basis, in line with our mission as an organisation to make architecture accessible to all. However, a few of the properties will require you to book in advance through them and contact details are given in the buildings listing. In 2013 there were no bookings administered by Open House and we will continue with this ethos for this years' programme.
In 2013, four buildings ran a ballot for admission the through Open House system. Those were: 10 Downing Street, The View from the Shard, EDF Energy London Eye and Gray's Inn.
Details for the 2014 ballot will be announced in due course!
