Shaped by extreme climatic variation, the gateway building shields passengers from harsh temperatures with its striking roof and envelope.

Formed by twelve, 18-metre-wide bays, the predominantly flat roof is engineered to evenly distribute snow loads, and is pierced by steep, inverted prisms that project above the roof datum and assist in disposing of meltwater. Within, the expansive, lofty terminal is illuminated by the prisms, which act as vast roof lights, drawing daylight into the building even in the depth of winter.

The faceted geometry of the soffit evokes the pitched roofs of St Petersburg and its surfaces recall crystalline patterns seen in ice and snowflakes. Its gilded finish reflects a warm patina to the interior and references the city’s golden domes and spires.

Organised to encourage simple progression through the building, the airport creates a dramatic yet logical transition for more than 12 million passengers each year.
