The former spatial structures have been broken up in order to create visual relations to the exterior spaces. The open space area in the centre is surrounded by retreat areas, individual workstations and ancillaryrooms. The ramp creates spatial zoning. With ﬂush fecotür S105 structural glazing door elements and fecotür H105 wooden door elements on both sides as well as fecostruct glazing and the fecowand solid wall, feco meets the high sound insulation requirements. In addition, acoustically-eﬀective wall surfaces with the fecophon 14/2 horizontal slits contribute to reducing reverberation times and improving room acoustics.
