On Finland’s windswept Turku archipelago, Helsinki-based design practice and log house kit purveyor Pluspuu has completed yet another ecological wood house — fittingly named the House on the Rocks. Designed to embrace landscape views in multiple directions, the three-bedroom, two-bath residence is a custom design based on Pluspuu’s pre-designed house models Isokari and Kustavi. As with all Pluspuu projects, the geothermal-powered log house is built primarily from timber and boasts a relatively small carbon footprint.

Completed last summer, the 150-square-meter House on the Rocks was constructed from 202 x 195-millimeter non-settling logs that are supposedly superior to the cheaper lamella log due to its flexibility of use without the need for post-construction adjustment. The solid log walls also mean that the house doesn’t need additional insulation aside from the eco-friendly wood fiber that insulates the sheet metal roof.

“The carbon footprint of the construction of a log house is extremely small, and the timber will act as a carbon sink for the house’s entire lifespan – this truly is eco-friendly construction,” the architects explained, noting that over 20% of all detached homes are log houses in Finland. “In addition to its environmental friendliness, a log house also has extremely healthy indoor air.” The home is also heated with geothermal heat distributed via underfloor heating.

Using Pluspuu’s pre-designed housing models as a starting point, the client worked with the architects to craft a site-specific dwelling that embraces outdoor views through large windows and a sea-facing terrace that’s over 100 square meters in size. The property also includes a freestanding Pluspuu Luoto 25 sauna as well as a two-room guesthouse on the shore; both structures are built from smaller 134 x 195-millimeter laminated timber.
