Kastelli-talot

What Kastelli-talot does

Kastelli-talot Oy is Finland's market-leading prefabricated residential construction company, operating since 1989 and headquartered in Oulu with a second main office in Espoo. The company designs, manufactures, and delivers single-family timber-frame houses, turnkey log homes (Hirsi-Kastelli), log holiday villas, and outbuildings (garages, carports, garden saunas), with a cumulative base of 30,000+ homes delivered. It has held the #1 ranking in Rakennustutkimus RTS Oy's Omakotirakentajatutkimus continuously since 1994. Three delivery tiers — Peruspaketti (basic shell), Viittä vaille valmis (nearly ready), and Muuttovalmis (turnkey) — are offered alongside proprietary branded options such as Kastelli Green (eco-friendly breathable wood structure), Kastelli Energiafiksu (smart home energy management), and the Kastelli Collection interior design service.

The company operates a B2C go-to-market built on a nationwide network of 30 Kastelli-kauppiaat dealers providing in-person consultation, plus model homes, housing fair participation (Asuntomessut), and increasingly digital channels including the OmaKastelli customer portal and KastelliBot AI assistant. Revenue is generated primarily through one-time house and outbuilding sales averaging around €215K–€266K+ for turnkey log villas, with ancillary revenue from installation services, the Collection interior design bundle (Puustelli, Tikkurila, Pergo, Tulikivi, Siemens), and the digital portal subscription. Kastelli is a wholly-owned subsidiary of Harjavalta-konserni, a Finnish family-owned conglomerate founded in 1920 that reported €369M in consolidated revenue in 2024 and 1,500+ employees across Kastelli, Puustelli Group, and Lapti Group; operations extend modestly into Estonia via K-Majad OÜ.
