Kokoon is a modular living unit built to address the acute shortage of temporary accommodation for asylum-seekers, students and residents displaced by building renovations. The prefabricated modules were designed as a living solution that can be easily transported and stacked in various configurations in order to fit numerous sites in urban and suburban contexts. Kokoon is one of the winners of Metsä Wood’s Open Source Wood award.
Kokoon modules have the potential to be mass-produced and assembled as multi-unit housing complexes. Kokoon’s three initial prototype units were designed and constructed by the Aalto University Wood Program team in Finland. They were prefabricated at the Aalto University Architecture workshop in Otaniemi, Espoo. Design of the units started in January 2016, and construction began in April 2016. The units were completed in a couple of months.

When it came to design development, the team explored several wooden materials for the construction of the modules. However, the material efficiency of
Kerto® LVL (laminated veneer lumber) allowed for minimal wall profiles to optimize the limited footprint imposed by the project parameters – a comfortable living unit that can fit on the bed of a truck for ease of transport. LVL not only provides the primary wall structure and the floor and roof substrate, it is left exposed as the interior finish, which reduces the layers of assembly and construction time. Kerto LVL Q-panels allowed for fast module production and offered the required load-bearing capacities. As a wood product, the extensive use of LVL also contributes significantly to the overall sustainability of Kokoon.
