ERWE Immobilien AG has secured another strong tenant for the planned new building on the former Ziellenbach site in Krefeld's city centre. A large share of the ground floor of the new building in the well-known prime location of the city centre will be used by AOK Rheinland/Hamburg after completion of construction scheduled for 2023. AOK has now leased office and service space plus an outdoor advertising area on the ground floor of the building and intends to operate a branch office with public access, training and conference rooms as well as office use there. The new quarter being built is another example of ERWE Immobilien AG's successful mixed-use concepts, with which the company has already implemented several inner city transformation projects.
