‘siemens hengelo’ by amsterdam-based firm NL architects is now complete in the hart van zuid district of hengelo in the netherlands. bordering a square and opposing the main train station, the office building is situated at the head of a strip of industrial structures. contextually defined by the 20th century production, the area encompassing the site is being converted into a lively sector of mixed uses including work and comfortable living. education and leisure will be integrated into the ongoing high-tech industry. the exterior responds to the zoning document’s prescribed aesthetic: ‘the shape should be derived from the industrial heritage: unambiguous, sturdy, stern and uncompromising. through these properties the building will acquire the character of a sign.’ this statement has been interpreted and implemented into the project by inverting the typical form of the horizontal shed and saw-tooth roof.

the zigzagged facade forms rows of inclined windows, positioned to reflect the pedestrians, cars, trains and buildings to onlookers viewing from below. framing the glazing, protruding elements act as a visor to reduce glare and reflections to those working inside. similar to traffic control towers, the employees will enjoy optimized outward views.
