Both the property side facing the city port and the street side to “Am Mittelhafen” require representative façades. Therefor a building in the north-south axis is required, which fills the property over the entire length. The two narrow views speak a suitably dignified language – to the waterfront through an invigorating silhouette that adds a building with personality to the row of existing office buildings. The opposite side facing the street is emphasized by an expressive façade – in contrast to the buildings in the immediate vicinity, which do not have such a concise addresses. This gives the quarter a much needed “urban flair”.

‘A staging of shopping’. The widespan shop outlet typology usually situated on the periphery is here reconstituted as an urban facade, city near and addressing the city bound / city exiting traffic. Three stores (RS, Yellow, Brands) with an overall shop area of 5.000 m2 cluster with warehouse and delivery bays, around an internal parking piazza. An advertising tower erupts on one corner, a supersign, a new actor in the quartier’s tower landscape (Trinity Church and Fire Station Tower).

A theatrically proportioned roof frames the pedestrian/car entrance. This transition space is a constructed perspective (rejecting any ideal viewing point), a reciprocal scenographic framing of inner and outer world. The hovering roof grows out of and connects the two larger shops. Logistics are critical – 18 m long lorries cross the piazza and disappear into the building.

The exaggerated scale of the wooden window frames in RS (which sells wooden furniture) are stacked like boxes (These 35 cm wide frames sidestep a local building regulation that prohibits wooden facades on retail structures). A dialogue between contained and container that continues in the interior detailing. Both structure (prefabricated concrete) and the materiality (fibre-cement panels) of the facades respond with an economic and systemized appropriateness to the ‘outlet’ building type.

The masterplan required two towers to mark the entrance to the Garden Show and Building exhibition. The big-brother of the pair, the giant, striped (Jacobs-coat) Sauerbruch and Hutton building, a new hive for Hamburg’s Planning Department (BSU) was not, according to the competition brief, to be upstaged by its neighbour. Already at the outset the bumpy road forward was in evidence when the black facade (no competition for polychromy) of the premiated BOLLES+WILSON entry was rejected by the developers of the railway-track side of the same block – not the right statement for their housing for the elderly. The facade mutated to green. “No green”, said the same developer, green is the colour of their chairman’s football team’s archrivals. The architects insisted that football allegiances is not a credible basis for urban planning decisions, and supported by the ubiquitous director of planning, the corner tower remained green. To get planning approval the developers were caused to sign a commitment that the green ceramic façade, a thematicised official entry to the Garden Show, would not be compromised during planning and construction. A wise requirement as fast track planning was necessitated by delays due to wobbly project financing around 2011. Further down the track a rapid rethink of the green facade was again necessitated by ‘just-in-time’ scheduling. The planed gluing of the rippled ceramic tile stripes would have to happen in winter (sub zero temperatures render glues impotent). A dry system of hung ceramic panels was at the last minute chosen and the respectfully stepping facade arrived as the IBA building exhibition opened.

The 9-floor tower is a medical centre, highly installed individual doctors rooms. Apartments and duplex penthouses with sculptural cut-out balconies occupy the top three floors. A darkening of the green ceramic facade signals a separate function for the four-floor wing to the south. This is the InselAkademie promoting sport for teenagers – not only from the surrounding Wilhelmsburg dockland district, characterised by social housing, immigration and unemployment. The upper floors of the InselAkadamie are group apartments for sporting youth and the lower two floors seminar and the temporary administration rooms of the IBA (International Building Exhibition). This building is in fact the hub of the IBA and also post IBA activities.

Entering the city from the north, a straight road, at the apex of its perspectival triangle a silhouette of cathedral and other church towers. Progressing into this picture, slightly downhill the view is gradually obscured, the outer traffic ring crossed.

The next 500 m rise, not a dramatic topography but enough to awaken expectation – ‘up there I will be in the city’. Buildings on the right enclose and to some extent counteract the latent drama of this ascent, this arrival. The left is undergoing a transformation, a re-configuring, a chance for a modulated roofline to enhance topographic character.

This is the intention of the sculpted silhouette of the new offices of the ‘Wohn+Stadtbau’ Housing Association. Its crest location is critical. The structured plaster façades of both volumes do not just echo but enhance site topography and the drama of entrance.

Entering the building involves a counter and smaller scale spatial sequence. The building front steps back from the heavily trafficked street to a transparent foyer. The ground floor facilitates intensive visitor traffic, waiting spaces extend into the internal court and playground.
