The Centraal Beheer building by Herman Hertzberger in Apeldoorn is a well-known project among architects worldwide. Designed for an insurance company, the office is widely seen as one of the high points of the structuralist movement. Now MVRDV, in consultation with Herman Hertzberger’s office AHH, is transforming the celebrated building, respectfully preserving its structure and making it the centrepiece of a sustainable, green residential neighbourhood that echoes the design principles of the existing building. Commissioned by Certitudo Capital, the transformation is part of a larger area vision for the three-hectare site near the city’s train station, with MVRDV’s design prioritising heritage preservation, greening, and innovation and introducing approximately 650-800 homes.The Centraal Beheer building was a revolution in office design when it opened in 1972. Hertzberger’s design consists of four quadrants, divided by two central “streets” that form the social heart of the building. By consistently repeating and adjusting the basic element, a 9-metre cube, the building acquired its distinctive form and remarkable interior. Half a century later, the building enjoys worldwide fame among architects and architecture historians.In 2015, Certitudo Capital purchased the now-disused building and its surrounding grounds with the aim of turning it into a multifunctional residential area. MVRDV developed an area vision which extends the structuralist principles of the building throughout the residential area. The axes of the central streets within the building will not only be a place for Apeldoorners to meet, they will also become a part of the most important routes through the area, better connecting the building with the city and the station and reinforcing Hertzberger’s original design vision.The Centraal Beheer building and the Pakhoedtorens, which are also part of the site, will contain a variety of housing. The original structure will be reused as much as possible, and refinished with sustainable materials. The project’s goal is not only to create as diverse a housing supply as possible, but also to turn the building into a destination complete with public programming, making the park an attractive place to visit. Transforming the existing building is not only important for preserving Dutch architectural heritage, but also for the environment: the CO2 emissions of the construction of this residential area are significantly lower than for regular housing.Just as structuralism is often characterised by the repetition of small units, the structure of Centraal Beheer will be continued in the new neighbourhood and the new landscape. The design of the new buildings will be based on the 9-metre grid of the existing building, but built in wood to distinguish them from the original parts of the design. The old building will be revived with new programmes and architectural elements, fulfilling the structuralist principles that it was originally built upon. The landscape will also have a clear pattern based on the grid, within which a “wilder” infill with trees, grasses, water, and play and sports facilities can be incorporated. In the following phases, a study will be conducted into which tree species can best be added to the park in order to stimulate biodiversity.MVRDV has much experience in revitalising disused public spaces and buildings. In Amsterdam, Tripolis Park is currently under construction, which renovates Aldo van Eyck's Tripolis office complex and adds a glass extension, which serves as a “soundscreen” to protect it from the dust and noise of the neighbouring motorway. In Utrecht, the masterplan for the new Jaarbeurs was launched at the end of 2019, ensuring that one of the oldest trade fairs in the Netherlands will retain its place in the centre of Utrecht.
