Residential building in the HafenCity district of HamburgThe HafenCity of Hamburg is beyond doubt one of Europe's largest urban developmentareas currently under construction. To avoid repeating the errors of past projects,great attention was paid on providing a balanced mix of work, commercial andresidential buildings. The house on the Kaiserkai is designed as a purely residentialbuilding, which enjoys special privileges due to its architecture.Despite the great attention it has been receiving, not manyhave expressed the desire to live in the newly created citydistrict of HafenCity. The appearance of this unfinisheddistrict has too little in common with the traditionalconcept of residences that is still closely associatedwith a green environment. Settling here requires acertain degree of pioneering spirit. But this courage isrewarded with a unique atmosphere of movement, change,international spirit and an excellent view coupled with anauthentic harbour feeling (including the noise of ongoingconstruction).This is particularly well exemplified by the building locatedon Kaiserkai 12. With its 11 floors, the oval residentialtower is slightly lower than its counterpart, the Marco PoloTower located further south. Due to its exposed locationit is even allowed to break out of the mould. It is locatedon a key visual and traffic intersection, connecting theHafenCity with the downtown area and in the vicinity of theprominent future Elbphilharmonie (philharmonic orchestrahall). At the same time it lies at the beginning of the Vascoda Gama square, which extends down to the Dalmannkaipromenade near the water, where it offers an unobstructedview of the still intact harbour activities on the oppositeside. The axis is additionally highlighted by the permeabilityof the ground floor. Six conically downward tapering steelconcrete supports with extremely flat ellipse-shapedcross-sections seem to effortlessly lift the structure off theground. Offset by ten degrees from the north-south axis,the shape of the building cleverly diminishes the effects ofthe wind loads. As a result, almost no wind is transferredto the ground level, which limits the amount of draughtsexperienced by passers-by in the street and waterfrontareas. The wind passes with moderate force along thecurved facade, creating a very pleasant atmosphere on thewavelike indented balconies on the south-western side.However, even when the winds are stronger, the room-highglazing provides a unique view of the Elbe river with all itssurprising weather-induced atmospheres. Depending onthe location of the flats, the view can also be of the city.The oval floor plan accommodates no more than three flatsper floor, which were handed over to the buyers completewith high-quality furnishings. The small flats (60 squaremeters) at the centre with one-sided illumination and thetwo large flats on each of the outer sides were alreadysold before the start of construction on the buildings. Onthe 10th floor the entire floor space consists of a single“residence”. This panoramic view from a single flat ofthe city, the harbour and the Elbe river is probably not tobe found often at this elevation in Hamburg. On all floors,the layout allows the flexible combination of flats. Thebedrooms and the stairway face the less spectacularnorth-east side. On this side, the facade appears ratherclosed off with narrow windows. Ceiling-high printedglass elements create a smooth outer skin, which beginsto shimmer depending on the incidence of light due tofoil placed behind it. At the apexes of the ellipse, the twodifferent facades meet, presenting passers-by with aconstantly changing look depending on their location.8
