Once in a great while, a building comes along that changes the feel of its surroundings. 100 High Street is that kind of tower: Timeless enough to be in tune with its location, bold enough to make a stirring statement of its own. Grand walls of glass and steel look stunning from the ground, and yield breathtaking views from within. A bright, modern entrance adds landscape and light to an already-bustling byway. It's a dramatic new presence on one of the city's oldest streets.
