Due to its symmetry and completely white exterior, the training centre is highly visible within the landscape park on the site of the former coal mine. The ground floor parapets consist of exposed precast concrete with white pigment additive, while they are clad in aluminium sheet metal on the upper floors. Pergolas with horizontal steel grating and bolted connections to each floor slab shade the offices and classrooms. On the ground floor, a 4 metres wide steel colonnade circumscribes the workshops and serves as a covered delivery area. It creates a sense of rhythm along the building volume measuring 95 by 145 metres and highlights how accessible the building is along all of its four facades.
The main entrance in the west leads into an entrance hall followed by an atrium that is 72 metres deep and as tall as the entire building. It connects all floors via cascading staircases. The cantina in the rear section of the atrium is an open space that is recessed into the floor by 45 cm. It is enclosed by tall benches that provide a certain degree of privacy, separating it from the other areas of the spacious atrium. Elsewhere the architects intended to avoid creating possible barriers: merely glass partition walls separate the atrium from neighbouring spaces. The facades along the upper floors feature mullion-free window strips with integrated, slim ventilation flaps. The structural glazing along the ground floor is supported by laminated safety glass fins instead of conventional facade posts.
Since the available time for planning and construction was limited to no more than three years, the architects employed industrial production methods for the shell construction as far as possible. Roughly 85 percent of the building shell were prefabricated, for the most part in the form of prefabricated concrete posts, beams, and parapets. 26 metres wide steel beams span the workshops. For fire proofing purposes, they were encased in reinforced concrete. For the same reason, the atrium, the seminar rooms and the glass facades on the ground floor were equipped with a sprinkler system.
