It was Open House London weekend recently, giving ordinary people the chance to see buildings that are not usually accessible. This also meant freedom to photograph some of the city’s hidden architectural gems.

We visited five central London buildings – Unilever House, an older shell containing a very modern atrium, the Art Deco brilliance of the former Express Building at 120 Fleet Street, The Royal Courts of Justice, the imposing Freemasons’ Hall and the grandeur of the Foreign and Commonwealth Office headquarters in Whitehall.
