What Interhomes does

Interhomes AG is a privately-held German residential property developer (Bauträger) headquartered in Bremen, founded in 1968 by Karl H. Grabbe, Madelet Grabbe, and John L. Vanco. The company operates as a turnkey housing developer, providing a complete "Rundum-Sorglos-Paket" from fully developed land acquisition through planning, construction, and property handover. Its product portfolio spans affordable terraced row houses (Reihenhäuser) for first-time buyers, mid-market semi-detached houses (Doppelhaushälften), high-quality detached single-family homes (freistehende Einfamilienhäuser), and modern city apartments (Stadtwohnungen), with entry-level row houses priced from approximately €299,950. Construction is executed to current DIN standards and "anerkannte Regeln der Technik," backed by a Festpreisgarantie (fixed price guarantee) and 5-year warranties.

The company serves owner-occupier families, middle-segment buyers, and a newer capital-investor segment through a direct-to-consumer sales model centered on fully equipped model homes (Musterhäuser) and regional offices across Hamburg, Bremen, Berlin/Brandenburg, Hannover, Ruhrgebiet, Rheinland, Rhein-Main, and Nürnberg. Sales channels include on-site Musterhäuser, regional open house events, online Immobiliensuche property search, the MyHome Kundencenter customer portal, and content marketing via blog, newsletter (CleverReach), and social channels. Operations are executed through a network of project and subsidiary companies (Projekt- und Tochtergesellschaften) enabling nationwide project realization with regional partners.

Interhomes is controlled by the Grabbe family, which retains majority ownership after more than 55 years; the company has no external institutional investors, no public listing, and no disclosed funding rounds. Leadership comprises CEO Frank Vierkötter (Vorstandsvorsitzender), Board member Frank Voßhardt, and Supervisory Board Chairman Bernd Wagemann. The firm holds a recurring "Beste Bonität" (best creditworthiness) certification from an independent rating agency. With 101–250 employees, the company sits among the larger overregional residential developers in Germany, though no financial revenue figures are publicly disclosed.
