'puukuokka' is a trio of wood-framed apartment buildings in finland

architecture studio OOPEAA has completed a wood-framed apartment complex in jyväskylä, a city in central finland. the development, titled ‘puukuokka’, comprises three multi-storey structures. the first was finalized in 2015, with the second building welcoming residents in 2017. now, with the completion of ‘puukuokka three’, the complex offers a total of 184 homes for single dwellers of all ages to families with children.

in order to provide environmentally responsible and high-quality affordable housing, OOPEAA explored the potential of modular prefabricated cross-laminated timber (CLT) construction. consequently, the entire load bearing structure and frame of the three buildings is made of wood. each unit is composed of two prefabricated volumetric CLT modules: one containing the living room, the balcony, and the bedroom; and the other housing the bathroom, the kitchen, and the foyer area.

the three buildings come together to form a block that, together with the adjacent kuokkala church designed by OOPEAA in 2010, forms a focal point for the neighborhood. ‘the vision is to provide the residents with a functional space that is rich in experiential qualities,’ explains the design team. the project combines the sense of privacy associated with single-family dwellings with the semi-public character of an apartment building.

the use of CLT modules, which were prefabricated in a local factory, made it possible to cut the construction time on site down to just six months per building, thus reducing exposure to finland’s winter weather conditions. the use of the material also made it possible to create a spacious and brightly-lit hallway and atrium space, while the insulating qualities allow residents to control the temperature of their own unit independently.
