We had them down as ones to watch in our 2014 Architects Directory and for good reason. Superunion haven't failed to deliver with their latest project, a creative space tucked away in the Kunstnernes Hus, the jewel in the crown of Oslo's art world.

The Oslo art hub is one of the earliest examples of Norwegian functionalism, designed in 1930 by architects Blakstad and Munthe-Kaas. The building continues to host some of the city's best contemporary art and can now add Superunion's design to its impressive catalogue. Atelier Felix is a flexible extension to the building's existing gallery, designed to accommodate a multitude of activities.

This small but perfectly formed room can be divided into three zones, a reading area, workshop and an exhibition space. A bespoke wall becomes a useful installation of floor-to-ceiling shelving and serves as a blank canvas for artists and the public to display temporary works. Behind, the shelving encloses a more private reading area complete with space-saving window seats.

A spiralling, sheer curtain acts as a flexible room divider and provides the option to separate the workshop area from the rest of the room. This weightless partition creates an intimate space without completely isolating it and still allows natural light to flood through.  A wall-length window opens up the room, and peers onto the bustling café below, allowing visitors to soak up the creative energy without any of the disturbances.

'We were inspired by the building we worked in,' explains architect Vilhelm Christensen, and so Superunion's main concern throughout the process was to honour the history of the building whilst still creating 'a new space with unique character.' The crisp lines and Scandinavian simplicity of the design mirrors the classical cubic form of the Kunstnernes Hus. The blue wall colour chosen by the architects was also inspired by the functionalist building as 'the colours were sampled from a fresco in the building's foyer.'

Thanks to their light touch and functionalist-inspired approach, Superunion has orchestrated a modern space, befitting its historical host.
