Amsterdam-based UNStudio has designed the 92m tower in Groningen, the Netherlands, which will house the Education Executive Agency and National Tax Offices.
Called DUO², it was realised through a public-private partnership called DBFMO comprising of Strukton, Ballast Nedam and John Laing.
The aerodynamic form of the building has been achieved as the result of extensive sun and wind studies with the building and designed to minimise material and energy use.
The terraces, rounded corners and façade design guarantee minimum disruption to the microclimate of the surrounding urban green space, while integrating sun shading, wind regulation and daylight penetration.
The team also included Arup as the engineer and Studio Linse as the interior adviser, with landscape design provided by Lodewijk Baljon.
The tower features 2,500 work stations, underground parking for 1,500 bicycles and 675 cars and a public park.
