As in the two previous construction phases, feco-feederle secured the contract for the supply and installation of the system partition walls due to it being the most economical supplier. Sparkasse also appreciated the non-destructive mobility of the walls. By carrying out the conversion work within the existing building, the bank is flexibly reacting to changing requirements and reusing existing elements. With its good sound insulation, fecofix flush-mounted double glazing enables both confidentiality and transparency. The doors are flush-mounted H70 wooden door elements with an oak decor surface on the corridor side. Inside Haus C, attractive, sustainable workplaces have been created in the city centre for an additional 130 employees, thereby underlining Sparkasse’s commitment to maintaining its liveliness.
