The founders of Dutch architecture studio MVRDV believe their project for Rotterdam’s museum+Boijmans+van+Beuningen'>Museum Boijmans van Beuningen offers a new model for how museums can take full advantage of their vast cultural collections.

Winy Maas, Nathalie de Vries and Jacob Van Rijs – who are transforming what was an art storage depot into an attraction in its own right – told Attractions Management that rethinking the art storage facility as something that “can take people behind the scenes” offers a way to better showcase some of the world’s most important cultural artefacts.

Called the Collectiegebouw, the building will store 75,000 European art works belonging to the city’s Museum Boijmans van Beuningen – which owns a collection of more than 140,000 artworks, including paintings by Van Gogh and Rembrandt.

While art depots typically hide unexhibited collections from view, visitors to the facility will be able to witness a hive of backstage activity. Restoration, maintenance and transportation of the stored art will all take place within view of the public.

Located within the OMA-designed Museumpark in Rotterdam, the Collectiegebouw will be a 14,000sq m (150,000sq ft) cylindrical building. An ascending route will lead visitors around a central atrium, with walls lined with the stored art works. The journey will end on the roof, home to a restaurant and a sculpture garden featuring the trees removed to make way for the building. Guided tours will take people into the conservation facilities where the art is restored by specialists.

“We proposed a building that combines introversion with extroversion,” said Maas. “Why? Because it is technically highly protective; there are 'zillions' of euros worth of art stored there. How to combine that with an attempt to make it more extrovert as a public facility in a park. We suggested having a public programme on the ground floor, a public programme on the roof, and in the middle the hermetic art sealed in the central void.”

De Vries suggested different tickets will be available for different levels of access to the galleries, and said private collectors will be able to rent space in the building and pay to use the expertise of the museum to help maintain their collections. “Instead of having just a publicly or privately funded museum, you can have a kind of hybrid,” she said. “It's a very interesting idea.”

Van Rijs described every one of MVRDV’s projects as “a new adventure”. He said: “As you become more experienced, there’s a danger that you can lose your edge. To prevent this happening, we invent new things, so that each project contains a twist.”

The facade of the building will be completely mirrored, creating an effect Maas likened to being on a countryside road where a mirror “shows you what is around the corner.”

“The park will be enlarging itself,” he said. “You can look around the corner everywhere. Despite its size it wants to dissolve. In the end that's the central issue of an archive – you want to be there and not there.”

The design for Collectiegebouw has been approved by Rotterdam’s city council. Construction is expected to start imminently and the attraction should open its doors by the end of 2018. At that time it will replace the museum’s existing storage space, which is located below sea level and has been deemed a flood risk.
