What Jämerä does

Jämerä Kivitalot Oy is a Finnish residential construction company founded in 1974 and headquartered in Espoo, specializing in individualized single-family stone houses built from monolithic aerated concrete (kevytbetoni). Its core technical differentiator is a single-material wall system — 375mm or 500mm aerated concrete blocks providing structure, insulation, and vapor barrier in one layer — eliminating additional insulation and reducing moisture and fire risks; the system has demonstrated airtightness of q50 ≈ 1.0 m³/m²h and thermal conductivity of 0.078 W/(mK), validated by Tampere University research. The company serves Finnish families building custom single-family homes on owned plots through three delivery tiers: material packages (~€460K–€2,600/m² for 177 m²), frame installation delivery, and the KO-VA turnkey package (~€522K, ~€2,950/m²) available in Uusimaa and Pirkanmaa, plus a MoveIN pre-built home channel for faster delivery.

Jämerä operates a sales-led, direct-to-consumer go-to-market combining a Finland-wide independent representative network with in-house field sales teams and studios/showrooms in Espoo and Tampere; it drives leads via an online Kivitalolaskin cost calculator and converts through in-person architect consultations and fixed-price contracts. Revenue mechanics are project-based (one-off fixed-price house deliveries) with the bundled Kivikoti architectural/structural/MEP design service included if the order is placed within three months. Jämerä is a subsidiary of Bauroc AS, the largest family-owned lightweight concrete group in the Nordics (≈€60M revenue, ~250 employees), which provides vertically integrated supply of raw materials, including the new bauroc GREEN low-carbon block line (44.6 kgCO2e/m³, 70% lower than standard). Recent product launches and partnerships — the Marko Paananen Jämerä Collection, Elisa Kotiakku solar co-marketing, Schneider Electric and Casambi smart-home integrations in Casa Onnenkivi (Lempäälä Housing Fair 2026) — reflect a strategy of deepening average deal value and brand differentiation rather than volume expansion.

Pricing is project-specific and not publicly disclosed; indicative prices range from approximately €460,000 for a frame-ready 177m² house to €522,000 for a comparable turnkey delivery (€2,600–€2,950/m²).

Broad incumbents
