Image caption This photograph by Anne Yong was taken as part on an ongoing project. She said: "I find beauty in all aspects and components of architecture, everything that goes into making a building as well as the finished product. Through photography, I try to capture everything that encompasses architecture in a creative and innovative way, which helps to shed light on the complexity that goes into making a building."

Image caption The Valleaceron Chapel in Castille La Mancha, Spain, is the subject of David Cabrera's picture. He said: "I can't explain with words the feeling when I was there. It's a very special project and difficult to get access as it's private property. Simply beautiful to photograph but even better to have been there."

The competition is run by the Chartered Institute of Building, and the overall winner is chosen by a public vote, which opens on 18 December 2015.
