Perkins&Will has completed the new European headquarters of Dar Group and its growing network of firms at 150 Holborn in London’s Midtown.
The workplace, which is on track to receive BREEAM Outstanding and LEED Platinum ratings, was conceived, designed, programmed and built by its own tenants, which include Dar, Currie & Brown, Introba, Penspen, and Perkins&Will.
According to Perkins&Will, the building’s design “fosters routine interaction and chance encounters between employees” across Dar Group’s firms.
Jo Wright, managing director at Perkins&Will, said: “Delivering a brief not only for several organisations within the Dar Group but also for Perkins&Will has been the greatest test of our multidisciplinary approach. I’d stretch to say this is London’s largest self-build, bringing together a huge array of world-class expertise intrinsic to Dar Group. The philosophy of seamless connectivity and comfort, as exemplified in 150 Holborn’s core and sculptural staircase, reflects the level of collaboration we saw throughout its design and development.”
“By reinvigorating Holborn’s public realm with new retail shopfronts, improved pedestrian access, and a living wall, we hope our site will reinforce the area’s reputation as one of London’s most important business hubs.”
