The headquarters is situated in a hilly, densely wooded area of the KEMA business park. The landscape was the main source of inspiration for the design. The building contrasts with its surroundings, but its siting and the strong connection between interior and exterior integrate it flexibly with the landscape. The diverse functions of the building are legible in the form and the materials: a concrete plinth encloses the partly submerged indoor car park, black basalt is used for the two storeys containing office space, glass for the conference rooms on the second floor, and glass plus silver-anodized aluminium for the strongly cantilevered directors’ suite on the third floor.

The building is a composition of contrasts, not only as regards form and materials but also in its alternation of closed and open volumes. As against the many contrasts visual design, the ground plans are straightforward and the circulation routes are self-explanatory. Glazed footbridges in the open entrance foyer link the staircases and lift to the working areas and conference rooms. A less obvious quality this architecture possesses is its advanced energy-saving design.
