PolarHouse

What PolarHouse does

PolarHouse Oy is a privately held Finnish residential construction company headquartered in Keminmaa, Lapland, founded in 1999 and operating for over 25 years. The company designs, manufactures, and sells prefabricated thermal log (lämpöhirsi) house packages for the Finnish market, with growing international sales in Scandinavia and the Netherlands. Its core proprietary technology is a thermal log wall structure (Lämpöhirsi) achieving a U-value of 0.17 W/m²K, roughly half the heat loss of traditional solid log construction, built around a vertical load-bearing frame combined with Hunton Nativo wood fiber insulation, a windproof board, and a ventilated air gap. Manufacturing takes place in dry factory conditions in Keminmaa, enabling wall elements (with pre-installed windows and insulation) to be delivered as ready-to-assemble units and erected to weatherproof state in 2-3 days.

The product portfolio spans two main lines — Mökit ja huvilat (Cottages & Villas, including Aava, Taiga, Nova, Saga, and Duetto series) and Omakotitalot (Individual Houses, the Polar series) — plus the 2025-launched Pienhuvilamallisto (Small Villa Collection) covering compact 40-70 m² models, and a semi-detached paritalo investment-rental variant. Packages typically price from approximately €50,000 to over €109,900 incl. VAT (€950-€1,200 per floor square meter, with turnkey construction from €3,000/m²), bundling wall elements, windows (Kaskipuun), metal roofing (Weckman Progantti), doors (Swedoor), insulation (Hunton), sauna components (Lapin Lauteen), kitchens (Puustelli), tiles (Laattapiste), and fireplaces (Tulikivi) into a single-supplier warranty-backed delivery with a 10-year structural guarantee. Customers include Finnish vacation home buyers in Lapland ski resorts (Levi, Ylläs) and the archipelago, individual house / omakotitalo buyers, rental property investors (often managed via Hilla Villas), and international buyers.

Go-to-market is sales-led and direct: PolarHouse distributes through a nationwide network of named regional sales representatives covering all major Finnish regions, supported by physical studios in Oulu and Porvoo and a dedicated international sales team. Marketing combines content (website with Finnish, English, Swedish, and Dutch versions, blog, downloadable house books), social media (Facebook, Instagram, LinkedIn), and cottage exhibitions. The company is founder-led with Sameli Lähdesmäki as CEO and operates without external venture capital, private equity, or public market exposure; a related entity, Nordic PolarHouse Oy, is referenced in privacy disclosures.

Product overview

PolarHouse is a Finnish residential construction company specializing in prefabricated thermal log house packages (lämpöhirsitalopaketit) manufactured at its factory in Keminmaa, Lapland.
