The Art of Building photography competition is an international showcase for the very best digital photography of the built environment. It is open to both professional and amateur photographers.
The competition is run by the Chartered Institute of Building and celebrates the creativity of the industry, the passion of the people who work within it, and the impact their work has on those who make use of the final construction.
Dezeen brought together 10 examples of parasitic structures that rely on a host building for support or services. Others include experimental housing for the homeless and a house-shaped wooden hut affixed to the side of a hotel. See them all following the source link.
