We were chosen as one of three local firms to redesign San Francisco's transit shelters. Large advertising corporations competed to win a contract to design, produce and maintain transit shelters that could also include advertising. We worked for ClearChannel/Adshel, the company that ultimately won the contract. Our design was runner-up.

An ideal sustainable design uses a minimum amount of physical energy to solve the problem. Our elegant design was the simplest of over 30 submitted by the various advertisers.

If a city's urban fabric can be thought of as a work of prose, the idea behind our design was to create a perfect punctuation mark that could be inserted in any paragraph. Not an exclamation point to be sure; more like a semicolon.

A design competition for an ubiquitous object at this scale brings out all of the critics.
