Ströher Collection
The amalgamation of the Ströher and Grothe Collections has now engendered both the wish and necessity of concentrating and exhibiting this collection of international stature in a fitting setting. A feasibility study outlined future options and opportunities.
Duisburg
Located at the confluence of the Rhine and Ruhr, Duisburg’s history and development are closely linked with these national waterways. Parts of the city are characterised by extensive harbour facilities and their secondary structures. In recent years, upheavals in the industrial sector and the changing traffic situation have led to a transformation process, where valuable inner-city areas became available for long-term urban development. In the process, the former inner harbour complex became one of the most important key projects.
Inner Harbour
Well-connected to the city centre, the A59 and the A40 motorways, an urban district was successfully created out of building structures of an industrial nature. This development was initially centred around the conversion of the former mill, Küppersmühle into the MKM museum. The charisma of this magnet, which attracts visitors from all over the country, is now to be further enhanced by an extension.
Property
Given its proximity to the nearby motorway flyover, the property’s development options are relatively restricted in terms of space. Development of the site would also deprive the museum of the future potential offered by a public space interfacing with the urban landscape.
Perception
Perception of the Küppersmühle is influenced by the very different speeds at which it is approached. On the one hand, the leisurely pace of the stroller about town, on the other, a few seconds of awareness by passing motorists. The uniqueness of the place is underscored by the Küppersmühle’s location on the inner harbour. From the north, it can only be seen by pedestrians from a great distance across the harbour basin. A continuous approach and gradually materialising view does not take place.
Collecting – Storing – Showing
Going back to the origins of museums, the distinction between storage and display was largely unknown. Museums were the curiosity chambers of keen collectors – warehouses for a variety of objects and, at the same time, display cabinets. Functionally separated in many modern-day museums, curators and collectors are again considering ways of overcoming the separation of display and storage. This breaking-down of the barriers between precisely defined areas in favour of an integrated whole is also reflected in art of the recent past and present. Conventional museum facilities cannot cope with these artistic concepts.
Project
Based on these insights about the site, the perception of the location and the changed demands on its function, a solution at once simple and drastic presents itself for the Küppersmühle site and institution – a simple, lightweight and translucent-looking cube placed on top of the Küppersmühle silo building as an extension. The silos, which in the past were only containers for material goods, are transformed into a connecting and accessing element between the parts of the building. They are retained in their raw, original material state.
The silos, long disused, are an important architectural feature of the Küppersmühle as an industrial monument. In their new function as circulation elements – they house lifts, stairs and services – they now fulfil a practical purpose and are not merely decorative props. The new cube on top is integrated in the overall composition of the Küppersmühle, itself built in an additive fashion typical of industrial facilities in the 19th and 20th centuries.
The extension is set on top of the silos in a clearly defined cubic volume, supported by a steel framework. The spatial organization of the exhibition floors is designed for versatile, flexible installation and displaying. The façade permits various views of the interior and above all a panoramic view of the surroundings. The interior design and architecture of the exhibition rooms is restrained. The focus is to be on the art and not architectural design and details.
The outer skin of the façade of the MKM Küppersmühle extension is of a single layer of ETFE film. Given the visibility of the building – both at great distance from the motorway running past the site and from a pedestrian’s viewpoint at the inner harbour – it is an important architectural element of the project. This ETFE construction sheaths the simple cubic volume, creating a clear, smooth outer surface that is both transparent and has an appearance of depth.
