LOCKED IN SERVITUDE THE DRAMA OF A BUILDING’S MAKING REMAINS HIDDEN: (Louis Kahn)

There is today an enormous potential in the re-scripting of grand industrial spaces, survivors from an epoch that had less trouble expressing itself and its mechanical or technical potency than our current mean and exploitative ‘global shopping-centre-culture’.

One thinks of São Paulo’s Fábrica da Pompéia by Lina Bo Bardi, London’s Tate Bankside, or the Zollverein Coal Mine in Essen, Germany.

This was our first reaction as our client drove his black Porsche into the rusting cathedral of Hannover’s ‘U-boat Hall’. Was it a panic reaction at the end of WW II to build a submarine production space so far from the North Sea? The structure of the hall had in fact been originally designed for a U-boat production site of a naval dockyard in Wilhelmshaven. As it turned out the enigmatically named ‘U-boat Hall’ was only finished in 1944 and was thus not used for armament production.

Now sliced like salami the ‘Industrial Heritage Structure’ is to house various commercial outlets – a mega Bicycle Emporium where racing bikes can be tested in the shop or this landscape of coloured furniture.

This is in fact two shops; RS (wholesome wood) and Yellow (sub-designer). BOLLES+WILSON have already realized their flagship store in Münster and the HQ Building, a rooftop lake above a ‘big box’ two-floor warehouse/distribution centre.

For the ‘U-boat Hall’ the rent was based on the square meters of the hall’s floor. The architectural question was how to maximize this floor area with a selling landscape and a back of house warehouse for customers to pick up their new sofa / table / lamp.

The magnificent scale of rusting columns, elevated crane track and skylight box, resist the invasion of domestic equipment, relegating it to the status of ‘a carpet of coloured pixels’ spread across the selling decks.

A knitting together of street lines and block interior in a modest scaled residential district. The theme is more Vitruvius’ comoditas than grand or explicit architectural narrative. Street lines, precise boundaries between public and private realms are anchored with a solid dark, oil-fired, almost industrial and implicitly north German brick plinth. In contrast the upper floors in white plaster transcend this intentional massivity through their material and geometric abstraction. The two layers dovetailed together framing private terraces and necessary setbacks.

The 26 apartments are vertically ordered. Small units suitable for elderly occupants or studio apartments with garden below, the larger first floor apartments have generous balconies while the upper two floors are organised as maisonettes. An urbane facilitating of daily life is in the interiors and layout achieved with a reduced material palette – wood, stone, plaster.

The 1992 Kita 102 in Frankfurt – Griesheim was one of BOLLES+WILSON’s first buildings in Germany. 22 years later it has been extended. What does it mean to revisit an early work? To measure if it has stood the test of time? Or even if the architectural themes of that time are still pertinent today?

What is immediately obvious is that a generous two floor, curvaceous and somewhat expressive sculpted volume is no longer feasible under today’s stringent budget restrictions (the political promise to deliver a kindergarten place for every child). The new extension is single storey, docking on to and sloping down from, an original 7 m high sport and sleeping hall.

The 3 original ground floor classrooms were for conventional pre-school kindergarten use, and the upper 2 rooms after-school homework facilities for older kids. The 3 new ground level classrooms extend kindergarten functions, kids can run out directly from group to garden.

The original building expands in width and height, a conical volume explained at the time as a metaphor for growing – spaces expand and contract as kids run from one end to another. A narrative scenario that extended to details like 2.10m high doors for teachers beside 1.50 m doors only for kids. Draconian budgets preclude such whimsical game playing in the new extension, perhaps it is also no longer the time for architecture to reflect on its syntactical potential. In the original Kita four windows conspired to inscribe a giant letter K across the facade. A readable building for children who are learning to read. Today it is left to colour to signify. A thematized May-Green has been here co-opted (as in almost every second contemporary Kindergarten) to signal a fresh, playful optimism. It is the only internal colour. Also a green horizontal beam/gutter above a south facing glass facade benevolently grows extended sun-blinds (also May green) to wrap the sunny side in a Mediterranean-like slab of shade. Window articulation is no longer expressive, a tough neighbourhood requires defensive measures if night cooling is to be activated.

What was in 1993 described, as an east-west slab turning its back to the noise of a nearby autobahn is now a very long east west slab, still turning its back and opening southward to an extended linear play-ground.

Leo’s Gate is the fourth building block on the site of the former ice rink in Münster. It marks the entrance to the Science Quarter from Steinfurter Strasse. The mixed use with catering units on the ground floor, flexible Coworking Spaces and Coliving Modules on the upper floors is multifunctional.

Different wooden constructions are planned depending on use and requirements. Floor-to-ceiling timber trusses with light ribbed ceiling slabs are used in the cantilevered Coworking areas. The 45 residential units are delivered as completely prefabricated and furnished wooden modules and are stacked over four floors.

All facade elements are designed in a uniform shade of red, which blends in with the entire ensemble of the historical Leonardo campus and the new brick buildings in the area.
