KöTower Secures Anchor Tenant and Obtains Building Permit

The landmark KöTower project at Königsallee 106 in Düsseldorf reached two important milestones at the turn of the year: shortly before Christmas, the building permit for the 17-storey office tower was granted and RKW Architektur+, a renowned company, was secured as the anchor tenant.

RKW Architektur + is not only the future tenant, but also submitted the building application for the trophy building as the designer. Where the Apollo Theatre once stood, the urban significance of the location is being continued, with the only new high-rise building on the Königsallee (Kö) becoming a landmark with its striking façade and setting new standards with 200 different plant species on the façade and roof gardens. In addition to energy-efficient features, the building offers unique selling points with a high degree of flexibility and a private outdoor area with terraces and balconies for each rental unit. The highlight will be the rooftop terrace at a lofty height with a panoramic view of the Kö and the state capital.

“Now that the development plan has been rapidly developed and the special civil engineering work is already in full swing thanks to a partial building permit, the full building permit for this new landmark on Königsallee has now been granted,” says Lord Mayor Dr Stephan Keller, praising the good cooperation between the state capital and investors. “The impetus generated by this project is completely transforming the southern Kö area as it transitions into the densely populated Friedrichstadt district. The KöSpitze area will focus on quality of life, greenery and gastronomy, and the arrival of a renowned architectural firm underscores that a new central attraction will be created here.”

“The KöTower meets market demand perfectly – it’s “deep green”, highly flexible, uniquely positioned as the only new high-rise on the Kö and a real trophy asset,” says Klaus Franken, CEO of Catella Project Management, delighted with the brisk demand in an otherwise rather sluggish rental market. “The Kö is getting a new highlight and, with over 300 creative architects, an additional target group alongside the promenade and dark suits.”

“After almost 30 years at our current location, we have decided on a new company location. It was an intensive selection process – we literally looked at half of Düsseldorf,” explains Dietmar Liebig, Managing Director of RKW. “The KöTower bears our signature as the architects who designed it, so we are particularly familiar with its qualities. With the new location, we are making an important decision for the future and taking a significant step in the further development of RKW.”
