That land will be the home of the Sir Henry Royce Institute for Advanced Materials, on which construction has recently started. Unfortunately, the new building will dominate the Alan Turing Building, being many storeys higher than it and 8 metres away from it.
Last autumn I took advantage of the excellent mid-October weather to take some photos of the Alan Turing Building that I knew would be unrepeatable because of the imminent construction.
Here they are, along with (at the end) two images taken in September 2015.
The first three images were taken on a Canon 5D Mark II with 16-35mm lens and the last two were taken on a Fuji X-T1 with 18-55 mm lens. These and other images of the Alan Turing Building are available at the Alamy image library.
