Grimshaw has released a video in which firm partner Mark Middleton along with several members of the project team take viewers to the construction site of Pulkovo Airport in St. Petersburg, Russia. Appearing in and around the cavernous terminal, which will one day service 17 million passengers per year, the architects break down the cultural and geographic inspirations behind the design (golden onion domes, the city’s islands and rivers) as well as its environmental and structural considerations (low-angle sunlight, expressive steel vaulting). The result is as clear and concise a description of the motivations and preoccupations of contemporary international architecture as can be found anywhere.
