What Oikos Group does

Oikos Group GmbH is a privately-held German holding company headquartered in Schlüchtern, owned by Goldman Sachs, that operates one of Europe's largest prefabricated home construction businesses across six sub-brands: Bien-Zenker (premium segment, 115+ years of experience), Hanse Haus (established mass-market brand since 1929), Living Haus (self-build/DIY-oriented since 2015), Oikos object construction (B2B serial and modular timber construction), lichtecht (3D visualization and digital real estate marketing), and CASAI (AI-powered digital advisor launched in 2025). The company's core technology is industrial prefabrication of timber-frame homes, combining factory-controlled quality with traditional craftsmanship and sustainable materials including plus-energy buildings. Revenue is generated primarily through one-time sales of prefabricated residential homes to private families (B2C) and through B2B serial/modular construction projects for project developers and institutional clients, with pricing on a quote-based model featuring fixed-price guarantees. The group delivered nearly 1,600 homes and generated over 570 million EUR in revenue in the most recent reporting year, with approximately 1,900 employees across its operating brands and a multi-channel distribution model combining dedicated brand showrooms, direct sales representatives, and digital advisory entry points.
