City Hall

The Glass Gonad

Save to my Account

Former Mayor Boris Johnson dubbed his headquarters the “glass gonad” and as you approach this dramatic building, you can see why. It’s only when you get inside and climb the ramp that spirals around the building’s interior that you understand the architectural vision. The squashed shape was intended to improve energy efficiency but the glass testicle received a “D” grade in its Energy Performance Certificate of 2012 despite solar roof panels and the use of cold ground water for cooling.

The public can walk up to the auditorium on the second floor and down to the lower level where a digitized image of greater London covers the floor. It’s kind of fun to get down on your knees and pick out landmarks.

The top floor, known as “London’s Living Room” is open to the public once per year on open house day, usually during the second or third week of September.
