The three-storey modular building for office and administration consists of 24 single modules. The external shell of the building was construction as thermal insulation compound system and got a dark-grey plaster. Due to a colour change to light-grey the entrance area got a visual accentuation. A serial of large subdivided windows are bringing a lot of light into the building.
The modular building was equipped with a fire alarm system and roof cupolas, a communication system for the complete administration and an access control with card reading system. The modern staircase is designed with granite and stainless steel. The office doors have been equipped with glass cut-outs and internal lamella blinds so that daylight incidence in the corridor is ensured but there is nonetheless a view screen.
At present, SÄBU erects a further three-storey modular building as extension to the library consisting of 15 room modules. Both buildings correspond to the Energy Saving Enactment (“Energieeinsparverordung - EnEV”).
