Mecanoo: Rabobank

Sittard is located in the rolling landscape of Limburg (The Netherlands), the province of the bronze-green oak and the soft yellow marl.

The cooperative Rabobank wanted to combine smaller branches within a large centrally-located advice centre near Sittard station.

Upon entry under the curved ceiling with sculptural skylights, you can survey, in one glance, the whole building and your curiosity is further ignited for activities on the upper floors. These are designed as staggering terraces that meander around the loft as a white ribbon. They invite you to take the zigzagging stairs and not the elevator. The focal point of the central hall is the auditorium which, remarkably, was not in the original brief. In this area, Mecanoo designed a staircase tribune that accommodates flexible workspaces.

The brushed oak panelled walls in the building form a unity with the tribune and furniture. Here, a transparent curtain with different shades of silver and blue designed by Petra Blaisse of Inside Outside runs on a 60-meter long track that winds above the tribune. Diverse spaces and atmospheres can be created by altering the position of the curtain parts. Silver squares in it reference the playful square windows in the building’s facade. It consists of special masonry of yellow clay to which marl has been added. The white-yellow mottled bricks are here and there interspersed with stones with a glaze layer in the small hole, creating a tactile facade.

The entire ground floor including the restaurant is open to the public. Both employees and customers can use the workplaces in the auditorium, just as in a modern public library. The upper office floors are only accessible to staff via a pass system on the first floor. Here you can choose whichever workplace suits your demands: a small room for concentration, a more spacious room for working in a team, a large zigzagging table where you can informally work and chat, as well as open areas for meeting and exchanging ideas, individual work stations along the mezzanine, niches in the oak wall and both small and large conference rooms for gatherings. To provide a high quality acoustic environment, the call centre has its own space on the first floor with a beautiful view. A glass separation ensures that it is visually connected to the rest of the staff.

The advice centre is rated BREEAM Very Good. The bank is connected to The Green Network in Sittard, which makes use of residual heat from the Chemelot industrial zone. The building has energy-saving installations, high insulation and triple glazing. Climate ceilings control ventilation, heating and cooling through radiation without moving air. In addition, the building has a flat panel air conditioning system facing south. In warm weather a transparent screen automatically drops in front of the glass facade. The screen reflects the solar energy, while the heat of the sun between the facade and the screen is mechanically extracted so that the auditorium remains pleasantly cool. Plenty of daylight is obtained through the numerous skylights and the large transparent facades.
