An office building dating from the 1970s with a car park in the centre of Amsterdam has undergone a complete metamorphosis. Functionally, spatially and energy-wise, the building no longer met the requirements of the modern-day. The architecture was modernised by stripping the existing building right down to the concrete skeleton and by fitting new façades and a new interior. In addition, two further storeys were added. A challenging assignment, due to its sensitive location right in Amsterdam city centre.

The trapezoid building volume with façades on the Huidekoperstraat and Pieter Pauwstraat roads, used to consist of three car park storeys and three office storeys. As part of the renovation, the office space has been enlarged and the number of car parking spaces reduced. The extension on the roof, a zinc roof encompassing sculptural, triangular windows, affords spectacular views over the city. Part of the car park has been transformed into lettable space to improve the interface of the building with the street.  The new double-height space on the ground floor features a generous reception and catering space. The flexible office floors facilitate workstations on the façade side and consultation and meeting rooms at the centre of the building. The entrance area has been upgraded and the traffic space with stairs and lifts has been completely renovated.
