Over 750 buildings will be opening their doors to the public for one weekend next month as part of Open House London, the Capital’s biggest architectural festival. For the first time Dr Williams Library will be joining in. They will be giving hourly tours of all the Library’s public areas plus the lecture hall on Saturday 17 September. Access to the building will be only through five pre-booked tours which are being managed by Open House (www.londonopenhouse.org). Online reservations for the event’s pre-booked buildings are now open and are expected to be very popular.
