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.

The reflective surface of the ‘dark green glazed’ brick animates a monolithic self-focusing form. An ambiguous surface alternating between the brilliance of the sky or the depths of black shadow. Mass is also the subject, a single building block in the urban fabric. A block further animated by the vectorial trajectory of the adjacent railway which instigates a façade curve and lean. A relatively simple slippage whose justification lies not in its formal but its tectonic resolution. Each brick course slips out one cm from the one supporting it. For the train traveller the WLV building is an event of a few seconds, its deflection perhaps only the effect of speed, its roof perhaps only temporarily hovering.

The three floors and 7.000 sqm of offices house a branch of local government that deals with the administration of psychiatric services. Shops on the ground and rooftop canteen-restaurant complete the sandwich. A specified planning module of 1.625 m results in a deep precast concrete fin on each axis, visible structure in unpainted concrete defining a window zone for heating, cable canals and glare blinds. From inside window frames disappear behind fins, to the south sun screens extend the internal ceiling line beyond the window. Systematised cellular offices are animated by contextual deflexions in the overall plan form, resulting in serpentine office strips, floating service islands, the ‘elastic plan’. Not high but low-tech is here and in the entire building thematizing, the simple, the well made, the long lasting.

The Cinnamon tower was conceived as freestanding campanile – a pin on a piazza was the concept behind the premiated competition design by BOLLES+WILSON for the existing 19th century Harbour Masters Building.

A tower was not anticipated in the competition programme, but the jury agreed that a tower anchors the public functions around the only remaining historical building to survive between the megablocks of the ‘Overseas Quarter’ master plan. The historic building will also be more autonomous.

Slenderness is essential for a campanile. Over the course of its 8-year gestation this was respected – even while its function mutated from stacked restaurants to housing. The 13 x 16 m floor plan tapers towards the top. With a height of 56 meters the tower is 4-times higher than it is wide.

How can such a thin chap be efficient?
The efficient answer is duplex apartments. Originally the concept foresaw seven apartments, each on 2 floors, a panoramic living deck on the upper level and bedrooms with punched windows below. Precise market analysis led to a variation of this formula: one triplex apartment at the top and some 1-floor apartments at lower levels. Built were ten apartments, four with 130 sqm, five with 185 sqm and one with 300 sqm. The tower has a gross floor area of 4.300 sqm and a volume of 16.000 cubic metres. At the ground level, the piazza level is a commercial area of around 300 sqm.

Strict high-rise regulations demanded an escape route from every floor via secured escape stair. The possibility to clean every window from the inside was also a criterion to be met. The spectacular view of the New Elbphilharmonie should not be blurred by dirty windows. Room-high windows on three sides of the living room also allow the tracking of incoming cruise ships.

Facade panels of anodized aluminium sheets in different gradations of dark red correspond to the patchwork of BOLLES+WILSON’s pavilion from 2008. This was the first realized component of the Harbour Masters ensemble. In sunlight these aluminium panels take on colourful nuances while on cloudy days they assume a darker, more serious Paul-Klee like appearance. This is a building that changes its character according to the incidence of light, a new figure on Hamburg’s skyline.

The Spuimarkt is a permeable block, it hosts the life of the city (tides and eddies of shoppers), it leads Bioscoop and other leisure seekers dramatically upward, and perches them in grand foyers, outlook windows, privileged vantages. The Pathé cinema foyer is a Piranesian space, its stairs flow dramatically upward, they cross, they hover. Just arriving at one of the nine cinemas (2,270 seats) is a cinematic experience – along the way some of the best views in Den Haag.

A richly textured brick facade gives unity and dignity to the whole block; the tactility of the rotated and projecting bricks is comparable to a tweed jacket, its hand-made quality both abstract and traditional. Spuimarkt’s sculptured corporal autonomy is carefully dovetailed into the wider context, mediating between the Bijenkorf and the City Hall to form a trilogy of major urban statements. The building’s varying scales respond to the surrounding context, the grand Grote Marktstraat facade steps down behind to the more intimate street scale of Gedempte Gracht. The lower Pathé cinema entrance reflects the height of the traditional houses it faces.

The sinuous roof silhouette, moulded around the cinema within, is like a topographic landform; an anchoring that gives measure and scale to the complex Den Haag skyline.
