This hugely popular, capital-wide annual festival of architecture celebrates its twenty-third anniversary in 2015 and takes place over the weekend of September 19 and 20. The festival allows access to hundreds of buildings not normally open to the public – private homes, government buildings, historic sites, educational establishments and many others.
See our Open House highlights here, and plan ahead to visit quirky venues such as the BedZED eco-village and London icons including Walthamstow stadium and the BT Tower.
Of the more than 800 venues involved, the vast majority will be open to all on a walk-up basis, but around ten per cent will require advance booking; for details of how to book see www.openhouselondon.org.uk.
To plan your itinerary in advance: pre-order a printed copy of the programme online until August 11 (normally £8.50; Time Out readers can claim a five percent discount until August 25 with the code LONDON); go online and browse the festival website (www.open-city.org.uk) when it goes live on Friday August 14; or download the Open House app (69p now; £2.99 from September 2), which makes it easy to put together your own personal itinerary.
