Workshop Siegen's distinctive form references the classic garage format with forecourt. The simple steel frame structure is fitted with fibreglass translucent panels to provide energy-efficient insulation and a softly diffused light inside, the latter feature facilitating productivity by creating a calm and relaxed environment in which to work. At night, the workshop functions as a light beacon, illuminating the main entrance to the industrial complex.
In addition to the panelling's insulation, light diffusing and signage properties, its sub-structural configuration, which comprises a series of horizontal seams, animates the grid like composition, as articulated by the mainframe and mullions. Collectively, these details accentuate the building’s dramatic cantilevered canopy.
Internally, a concrete box, housing the office and washroom facilities, stabilizes the main structure via a series of horizontal and vertical steel struts. This arrangement eliminates the need for external cross bracing, so allowing an aesthetic clarity to be achieved in the outer skin, thereby maximizing its impact as a light beacon. Only standard industrial products were used in the making of Workshop Siegen.
