The 1990-93 shiny aluminum shed was the first of three big-box warehouse buildings built successively side by side to store and distribute furniture for the ever-expanding chain of RS + Yellow Shops. As well as this home base BOLLES+WILSON built for the same company shops/outlets in Münster, Hannover, Munich and Berlin.

The dimensions and form of the 1993 RS+Yellow Distribution – Phase 1 were prescribed by the ruins of a half-built industrial structure. The problem was to economically clad this given form.

The skin of corrugated aluminum has been seen as a reference to Australian wool sheds, a typology here projected to a length of 120 m. It landed like a UFO in its fragmented peripheral context. At the time B+W were propagating such large self-evident forms (see Technologyhof Münster 1993) to anchor and give scale to the fragmentation of ubiquitous post-industrial Eurolandschaft Fields.

The critical detail for RS+Yellow Distribution – Phase 1 was the façade section, two intersecting plates of shiny metal. Avoiding a capping plate as well as regular downpipes, that would compromise such a pure extended surface, runoff water from the barrel-vaulted roof courses down the inside surface of the upper façade panel to be delivered in turn by the lower façade panel into a pebble drain at ground level.

The rear end of this super-shed housed the office of the company owner, this subsequently moved to the spectacular Waterscape rooftop of RS+Yellow Distribution – Phase 2 built directly beside RS+Yellow Distribution – Phase 1. A third adjacent big-box was to be capped by the client’s rooftop villa (RS+Yellow Distribution – Phase 3) but his tragic death meant that it was completed as meeting rooms, standing in another infinity pool.

When is a warehouse a lake? – in Münster.

This is the third BOLLES+WILSON building for the German-wide furniture chain RS+Yellow, an extension of the homebase storage and distribution centre by 7,000 sqm. The new rectangular building volume stands adjacent to the original 1992 corrugated aluminium warehouse.

The 60 x 66 m two stores ‘Big-Box’ is (as is usual for industrial architecture) reduced to a regular grid of pre-cast columns and widespan floor slabs. Facades are a standard lightweight concrete system. Verticality is emphasised with pyjama colour stripes interspersed with zinc coated grid stripes. These absorb all windows and necessary smoke outlets into an uninterrupted colour curtain.

This warehouse and even perhaps the 1,500 sqm of offices above the delivery bays are precisely realised but relatively conventional. The big surprise comes on arriving at the rooftop meeting rooms and executive offices. Through the intervention of the fire brigade (choreographed alarm) the roof of the building has been flooded – a 45 x 65 m reflecting pool.

The edge detail, laser levelled into invisibility, increases the metaphysical unreality of this sky reflector. Underwater compartments eliviate the risk of mini-tsunamis. Spillage is collected in edge channels and channelled to an internal cistern.

A wooden boardwalk fronts the large format sliding glass facade. A pier extends out to the centre of the water world. Here one can sit surrounded by geometric groves of bamboo. From here the south facing glass front of the roof pavilion reflects again the rippling expanse of water. The facade itself is shaded by a projecting steel pergola and a curtain of louvers descending at the press of a button from its outer edge.

This choreographed overlap of inside and outside, of natural and artificial, of direct and reflected light, create a unique atmosphere which could be described as an industrial scaled Japanese Tea-House.

The principal element, a Blue Glazed Brick Wall corrects a disastrous alteration and also breaks the tyranny of uniform ceiling height.

The second added element, a Zinc Clad Studio Box stands adjacent the Blue Wall. The two set up an external and internal play – geometric volumes – the abstract language of the plan respected and developed.

A very modest commission, careful details with the potential of enhancing the everyday lives of their users.

The Münster Library was BOLLES+WILSON’s first major public commission. After more than ten years it remains near the top of Germany’s ‘library-user-ranking-list’. A verification not only of functionality but also of the attention to detail, to spatial multiplicity and to the ambience and atmosphere within.

The complexities of the overall building form are derived from internal organisation and from a careful re-constitution of the fragmented context. A new pedestrian street on the axis of the nearby Lamberti Church divides the not inconsiderable mass of the Library. This fissure in the library volume is closed with folded screens (copper outside, acoustically absorbing perforated wood panels within).

A transparent entrance zone (café, newspaper salon) leads via an information supermarket to the main information desk on the connecting bridge. This in turn is adjacent to book stacks in the ship-like outer volume. The atmosphere is quiet, studious. Books line the outer curved wall, a dramatic stair leads down through a 22 m void to the basement media library, which connects in turn to the courtyard facing children’s library and back up to the entrance zone. Up to four thousand users enter the Münster Library on one day.
