The station hall and municipal offices form a new landmark in Delft. The complex is located above a new underground train station, with the municipal offices accommodating one thousand employees. When the station is operational, the old railway viaduct that divided the inner city of Delft will make way for an extension of the city centre, a park and canal.
Designed without an apparent front or rear, the glass building is compact and flexible. Incisions in the glass volume echo the networked structure of laneways in the historic city and admit daylight deep into the building. Lowering the roof line at the corners reduces the building height to enable a gradual transition to the surrounding buildings.
In words of the architects: ‘Throughout the design process the building volume has been shaved and reformed to create a compact, highly efficient building form. The lowered roof lines at the corners provide a gradual transition towards the existing small-scale development of the Delft city centre and the adjacent Wester Quarter. Incisions in the glass volume form a pattern of alleyways and courtyards, which are themselves inspired by the intricate structure of Delft itself.
‘The glass skin of the building is designed to reflect the Dutch skies. The panels of fused glass with lens-like spheres reference a vernacular window design that can be seen throughout the historic city. The combination and rhythm of open panels of high performance glass and closed fused glass panels enable a high degree of energy efficiency.’
The use of clear glass at ground level facilitates a close connection between inside and outside. Here, the public zone with the station hall and public lobby is differentiated from the private section with the municipal offices made from transparent and molten glass elements.

The halls are separated by a glass wall and two volumes that house the public counters, consultation rooms and technical services of the municipal offices, and the commercial functions of the station hall.
The facilities are organised so that travellers can immediately glimpse the historic city from the station hall. Measures including a geothermal heat pump and an optimal facade design featuring highly insulated glazing enable a 35% reduction in energy use from prescribed requirements. The building accommodates solar panels on the roof that can generate a minimum of 20% of the building’s energy needs.
