Twelve built environment photographs from around the world shortlisted for annual CIOB photography competition
The CIOB has shortlisted 12 photographs of the built environment from around the world for its annual Art of Building competition.
The images include skyscrapers, a London underground station, a tiny Spanish chapel and the interior of a 17th century Danish observatory.
There are also examples of human interaction with the built environment, from a man climbing a bridge in Bangladesh to a hand tying steel rods together in India.
Nature also be seen intruding onto structures, most dramatically displayed in Iceland where the side of a mountain appears to be swallowing a small hut.
You can vote for the best image at www.artofbuilding.org.
Voting opens on 18 December and closes on 23 January, with the winner - who will receive a £3,000 cash prize - announced on 8 February.
