Kranhäuser
Three striking high-rises in Cologne's Rheinauhafen whose inverted-L silhouette mimics harbour cranes extending their jibs toward the Rhine.
The Kranhäuser (Crane Houses) are three landmark high-rises in Cologne's Rheinauhafen harbour district, forming one of the most recognisable skylines along the Rhine promenade.
At a Glance
- Type
- Three high-rises (two office, one residential)
- Location
- Rheinauhafen, Im Zollhafen 12, 18 & 24, Altstadt-Süd
- Dimensions
- 61.60–61.91 m tall, 70.20 m long, 33.75 m wide
- Total floor area
- 52,950 m² gross (all three buildings combined)
- Construction
- Foundation stone laid 16 October 2006; Kranhaus Nord opened October 2010
- Inspiration
- El Lissitzky's Wolkenbügel (Cloud Iron, 1924)
The overhanging upper section of the Kranhäuser starts only at 40 metres height and rests on a single slender, fully glazed stairwell tower – to achieve this structural feat, the architects drew on knowledge from bridge engineering.
Things to do here
- Marvel at the striking crane shape of the three high-rises

Design and Inspiration
The buildings are a contemporary interpretation of El Lissitzky's 1924 Wolkenbügel concept. Their inverted-L shape evokes three harbour cranes, with the cantilevered arms pointing toward the Rhine. The design was developed by Aachen architect Alfons Linster in collaboration with the Hamburg firm Bothe, Richter, Teherani.
Engineering
The structures use a steel-lattice frame. Above a height of 40 metres, a split cantilever projects outward, resting solely on a slender, fully glazed staircase tower — a solution borrowed directly from bridge-building engineering.
Use and Layout
The three buildings were constructed in sequence. Kranhaus Süd and Kranhaus 1 each have 15 floors and serve as office buildings. Kranhaus Nord is the only residential tower: across 18 floors and 15,000 square metres, it houses 133 owner-occupied apartments, all with Rhine views. Because residential floors require lower ceiling heights and live loads, the three buildings reach nearly the same overall height despite differing storey counts.
Copyright Dispute
The question of authorship led to a legal dispute between the Hamburg firm and Alfons Linster. On 26 February 2009, Germany's Federal Court of Justice ruled that Linster is to be recognised as co-author of the Kranhäuser.
Awards
The middle building, Kranhaus 1, won the MIPIM Award in the "Business Centre" category at the 2009 property fair in Cannes. The following year the project received a commendation at the Cologne Architecture Prize (KAP).
