Urban Architecture Exteriors in Black and White

Brief

This contest is for your black and white photos of exteriors of urban architecture. You can show any style or age of architecture of buildings found in towns and cities, whether residential or commercial, anything from a large modern structure with clean lines and shapes, to the more mundane buildings of a local housing estate. Please only enter photos in black and white, and ensure the architecture is the main focus of your image. I look forward to your entries.
