The pavilion’s design process addressed the challenges posed by its dual intended locations. It was required to function as a striking sculptural centerpiece in the heart of Helsinki’s city center while also serving as a permanent, functional structure at a suburban railway station. The wood structure’s details were developed with sustainability as a priority while maintaining a sculptural appearance.

The design was increasingly guided by the pavilion’s permanent function and location rather than its temporary role. The need for efficient transport and logistics resulted in an elongated shape. The structure was designed for quick assembly at Kansalaistori and reinforced to withstand transport. Conventional lumber was used to construct the pavilion, which was designed as an innovative wood structure. The interior was conceived as a pass-through space with excellent ventilation, accommodating potential uncertainties related to the coronavirus situation during the event.

Features for displaying information and playing music were integrated into the design. Stiffening boards in the wood structure serve as notice boards, while lighting and speakers are mounted onto the beams. A covered terrace was added to provide seating and a vantage point for observing the “micro climate change” installation, represented by melting ice blocks on the square.

At the railway station, permanent benches and ample lighting were installed under the shelter, enhancing security and usability in the dark surroundings. The wood joints were developed during construction in collaboration with joiners Markku and Ville Tonttila, ensuring high-quality craftsmanship.
