You get an idea of the scale of the building, wall and how close the road is from this shot. It's a measure of the security that bollards and placed on the street, with a gap for deliveries. A huge section of reinforced wall is pulled back to let lorries in.
I have all these photos as original 8MB shots. They're taken by a Canon EOS 20D, so they're good enough to be run A3 size at magazine (300dpi) quality. If you're interested in purchasing print rights, get in touch.
