Bloomberg’s European headquarters has won the 2018 Riba Stirling Prize for architecture.
Designed by Foster + Partners, the £1bn development was praised for “rethinking the office building format” and creating new systems to make it “the most sustainable in the world”.
Sir Robert McAlpine was the main contractor on the project, which delivered a 1.1m sq ft office made up of two buildings connected by a bridge, sat either side of a new public arcade.
Riba said the headquarters’ focus on sustainability was driven by Bloomberg CEO Mike Bloomberg, who “wanted to create a cutting-edge design that would push the boundaries”.
Judges unanimously voted to award Bloomberg the prize, describing it as a “once-in-a-generation project”.
“[It has] not just raised the bar for office design and city planning, but smashed the ceiling,” said Riba president Ben Derbyshire.
Foster + Partners originally secured planning permission for a building more than double the height of the 10-storey block.
Foster + Partners senior partner and lead architect Michael Jones said: “Behind every good building is a great client and Bloomberg is a testament to what is possible when the visions of client and architect align.
“We were continually supported and inspired by Mike Bloomberg and his team.”
Sir Robert McAlpine was named Environmental Contractor of the Year at this year’s CN Awards, with judges citing its work on the Bloomberg project as a testament to its sustainability credentials.
The HQ was awarded what is said to be the highest ever design-stage BREEAM Outstanding score for a major office development.
