Werkhof Bülach Building – Industrial Efficiency and Robust Design by Felgendreher Olfs Köchling Architekten

Located in Bülach, Switzerland, the Werkhof Bülach Building by Felgendreher Olfs Köchling Architekten is a striking example of functional architecture that blends industrial efficiency with architectural clarity. Completed in 2021 and spanning 5,500 m², this road maintenance complex forms a cohesive ensemble alongside the existing Bülach Police Station, reinforcing the identity of the local infrastructure hub.

A Dual-Building Industrial Complex

The project is defined by two distinct structures, each with a specific purpose:

• The Cold House (Garage and Storage) – A single-wall concrete construction designed for durability and long-term adaptability. This vast, open-span space accommodates road maintenance vehicles, heavy machinery, and equipment. Minimal interior pillars and multiple access points allow for flexible maneuvering and operational efficiency, ensuring that the facility can evolve with future needs.
• The Warm House (Administration and Workshop) – A two-shell structure featuring a concrete exterior and massive load-bearing timber construction on the interior. This building houses administrative offices, staff facilities, meeting rooms, and workshops for road maintenance crews. The warm, natural timber interior offers a contrast to the robust concrete shell, creating a welcoming environment for workers.

Functional Expression Through Honest Materiality

The architectural language of the Werkhof Bülach emphasizes functionality, resilience, and clear construction logic. All technical systems—including lighting, silos, fencing, and exterior staircases—are intentionally exposed and constructed in galvanized steel for both visual honesty and ease of maintenance. This approach reflects the building’s role as a working infrastructure hub rather than a decorative landmark.

Roof Design and Urban Integration

The complex is unified by plain pent roofs, each oriented in opposite directions. This creates a dynamic facade rhythm while ensuring efficient water drainage and structural stability. The high side of the administrative building establishes a strong street-facing presence, forming a clear entrance and architectural “address” for the complex.

From the street, the elongated facade reinforces the industrial character of the surrounding area, while the internal arrangement supports smooth operational workflows.
