This single-family home on the shores of Lake Joutjärvi is a prime example of sustainable construction and innovation. Particular attention was paid to environmental friendliness, reusability, and low-carbon materials during the design process. Designed in collaboration with Peikko and Sweco Finland Oy, the house is a pioneering sustainable construction project that is set to transform traditional building practices.
The project is centred on the concepts of structural reusability and minimising emissions in the short and long term. This has been achieved through the use of bolted connections in the structural frame, which allow the components to be easily dismantled and reused.
Peikko's sustainable alternative, the DELTABEAM® Green composite beam, has a carbon footprint half that of traditional steel beams.
Low-emission materials were also used for the hollow-core slabs and columns, and renewable energy was utilised in the production process.
Recycling and reusing construction materials are key principles of sustainable building.
The house's structural frame has been designed so that it can be dismantled and relocated in the future. Bolted connections allow the structure to be taken apart, and special threaded connections fix the hollow-core slabs and DELTABEAM® beams, making reassembly straightforward.
While Finland has a long tradition of recycling and repurposing old materials in construction, new methods and solutions will be required in the future to preserve the value of materials.
Peikko is continuously developing low-carbon products and solutions that promote the dismantling and reuse of building structures.
Glass structures play a significant role in the house's design, providing expansive views and abundant natural daylight.
An aluminium profile system was used to secure the glazing, which provides greater rigidity than timber fixings.
All the glazing is safety glass, and due to the large glazed areas, the structural calculations were carried out with great precision.
To prevent the typical greenish tint from becoming pronounced in thick multi-pane glazing, the glass was manufactured using extra-clear low-iron glass.
The windows also incorporate a solar control coating to prevent the interior from overheating and reduce cooling energy consumption.
The façade glazing consists of 12.8 mm Pilkington Suncool Optilam™ 70/35 OW, a 14 mm cavity, a 6 mm Pilkington Optitherm™ S1 NOW centre pane and a 12.8 mm inner pane of Pilkington Optilam™ OW.
Approximately 150 m² of triple glazing was used in the façade.
Through the collaboration of Arkkitehtitoimisto Pet Michael Oy, Sweco Finland Oy, Peikko, and Maakunnan Lasi Oy, this model project for sustainable construction was created, combining innovative structural engineering solutions with responsible design.
This single-family house on the shore of Lake Joutjärvi is a prime example of the future direction of construction, where ecological and sustainable solutions play a key role.
