Gateway Towers by I.M. Pei, Singapore

There are a few buildings I regret not getting betters photographs of while I lived in Singapore. The Gateway twin skyscrapers, designed by I.M. Pei, jumps to mind immediately. They are neither particularly tall nor centrally located. However, their mind-bending simplicity and structural engineering will never cease to capture the pedestrians' imagination as they look up at a paper-thin cliff of metal and glass rising from the ground to defy gravity and reason.

The 150-meter towers stand immediately opposite the Duo, designed by Buro Ole Scheeren and DP Architects.
