The open communicative room structure largely dispenses with revolving doors. Sound propagation is limited by fecowand wall panels and glass, room-high fecoplan sound screens. The acoustically-effective surfaces of the solid walls, sliding-door cabinets and sideboards as well as the fecophon Stoff, fecophon Metall and fecophon Holz sound absorbers mounted in front of the glass elements reduce reverberation times. The corridor glass walls of the two meeting rooms are designed with fecostruct frameless, flush structural double glazing with high sound insulation. The design themes forest, air, water and city with matching wall motifs, colours, floor coverings and objects are assigned to the various departments. All the communication zones are accentuated and highlighted with atmospheric luminaires. Lavigo luminaires from Waldmann provide biodynamic lighting at the standing/sitting desks. To create space for plotted plans, feco-feederle has together with vitra developed a special Tyde desk system solution with a table length of 2.80 metres. Agile working in the IdeenReich has improved communication across departments and strengthened team spirit.
