The head office of Philips Electronics Netherlands was designed in 1965 by architects firm Roosenburg-Verhave-Luyt-de Longh (currently LIAG). The office floors are suspended on external suspension stays, which are anchored on enormous steel cross beams that translate the forces to the core of the building. The core is constructed of a central stabiliser core and two end cores, containing stairwells, lift shafts and vertical transport ducts. Philips chose LIAG for the renovation/redesign of the high-rise and a replacement building for the low-rise. The new building was placed like a glass envelope over these sections. What was previously exterior has now become interior. The lighting in/around the building was given special attention. Openings in the roof are used to light up the base of the building. This has transformed the head office into a beacon light for Philips in the city of Eindhoven.
