NATO Headquarters

Skidmore, Owings & Merrill LLP as Architects

Like fingers interlaced in a symbolic clasp of unity and mutual interdependence, the design for this international treaty organization headquarters represents its changing mission from opposition and prevention to unification and integration. Designed in association with the Bruxelles, Belgium based firm Assar Architects, this landmark provides each member-nation with embassy-level security and privacy while also providing shared space where national representatives can meet as partners in the pursuit of peace and comity. Flexible office layouts and shared amenities yield an Office Urbanism that brings nations together

New NATO Headquarters

Assar Architects as Architects

NATO is building a new headquarters because the current headquarters is at the end of its economic lifespan and is costly and labor intensive to maintain. The decision to replace the existing headquarters was taken at the Washington Summit in 1999.


The new headquarters will provide space for: • 28 embassies from NATO nations • 1,550 NATO nation delegates; • 1,700 NATO international staff (civilian & military) • 800 staff from NATO agencies • Currently, an average of 500 visitors per day


Benefits • The new headquarters will be a unique opportunity to transform NATO business practices to achieve smarter and more effective new ways of working. • It will improve the level of physical protection. • The new HQ will be a step change in terms of working conditions and with modern facilities.


New NATO headquarters gets the largest zinc roof in Europe

NATO HQ with a stunning & durable zinc roof

The new NATO headquarters in Brussels has the largest zinc roof in Europe. The roof spans a total surface of no less than 35,000 m² of NedZink NOVA Pro-Tec standing seam bays in seemingly unmanageable lengths of 26 metres. A challenging project in many respects.


The new impressive NATO headquarters was designed by the American firm Skidmore, Owings & Merrill (SOM), which designed the Burj Khalifa in Dubai and the Time Warner Center in New York, among others, and ASSAR Architects from Belgium. The wedge-shaped headquarters comprises eight wings, which, SOM explains, interlock, thus symbolising the changing role of NATO since the end of the Cold War. Since then, the Alliance has increasingly evolved in the direction of integration and unification, with 28 permanent members and 19 partner states.


The eight wings, each 200 metres long and 18 metres wide, are fitted with a curved roof, as well as seven transition pieces above the connecting section, the 38-metre-high agora. In total, the roof spans no less than 35,000 m² in sleek standing seam bays of NedZink NOVA Pro-Tec. The roof construction consists of a steel deck with profile sheets used as a support structure, and subsequently, a 100-mm layer of Foamglas with the zinc standing seam bays fixed on top. The Foamglas guarantees a vapour-proof roof construction. The Foamglas system is thinner and can be used in virtually any shape. There are hardly any limitations with regard to the form, gradient, or length of the roof surface. The system is ideal for standard NedZink material and NedZink NOVA Pro-Tec with a coating on the back.


NedZink NOVA occupies a unique position on the market. NedZink NOVA is a processed, pre-weathered, titanium-zinc produced using a chemical surface treatment applied after the rolling process. The result is a matt, brushed surface in a natural grey colour. Since work on the NATO headquarters had to be performed at a height of 38 metres, NedZink supplied the NOVA Pro-Tec at the construction site in coils. Standing seam bays were subsequently profiled on the ground floor, in lengths of 26 metres, lifted on to the roof by crane, and secured with clips. It took over three years to manufacture this gigantic roof, and work was carried out between 2013 and 2016. All in all, it was a highly challenging project.


At NedZink, quality and service take centre stage. With the knowledge that extremely high requirements applied to this unique project, in terms of the quality of the products used and their processing, the Brussels NATO headquarters serves as incredible recognition for NedZink. It has elevated NedZink to a higher level.
