Sara Cultural Centre, Skellefteå

Timber innovation

The regional forest industry and construction knowledge play an important role in the project and is complemented by recent developments in engineered timber (CLT) technology. The advancement of research in engineered timber has unleashed a world of previously unimagined design possibilities. Collaborating with structural engineers Florian Kosche, two different hybrid construction systems have been developed; one for the cultural centre and one for its sibling structure, the hotel.

The high rise, which houses the hotel, is constructed of premanufactured modules in cross-laminated timber (CLT), stacked between two elevator cores. Thanks to the placement and design of the cores, they can be entirely made from CLT. Standing 69 metres tall, the 19-storey hotel offers dramatic views that stretch for miles over the city from one of the world’s highest timber framed buildings with glue-laminated timber (GLT) pillars and beams.

In the lower part of the complex, the cultural centre, the floors are made from a HBV-system (Holz-Beton-Verbund). This hybrid of concrete and timber redistributes loads from the high rise and enhances structural stability, while also improving acoustics between floors.

The characteristic trusses above the grand foyers are composed of a GLT and steel hybrid that enables a flexible, open-plan space that can host a range of activities and functions within. Flexibility of use guarantees the building’s long-term sustainability by allowing it to adapt to future demands.

The glass façade wrapping the building reflects the sky while revealing the spectacular exposed timber-framed ceiling inside. This ceiling is a recurring motif that guides visitors through the venue. The wood construction is designed to endure Skellefteå’s harsh weather conditions, while also remaining energy efficient. The green roof contributes to thermal insulation, as well as absorbing noise pollution, enhancing biodiversity and delaying rain water run-off.

A celebration of making

Sara Cultural Centre uniquely celebrates the craft behind the creative process. Open layouts combined with generous glazing reveal the ingenuity and skill involved in set-building and exhibition installation to visitors inside the building, as well as passers-by outdoors. At the heart of the centre lies a stage, its productions visible to the outside world. Similarly, exhibitions can be programmed at the entrances, inviting non-traditional gallery goers into the centre.
