What Regnauer Hausbau does

Regnauer Hausbau is a family-owned German timber construction company founded in 1929 and headquartered in Seebruck/Chiemsee, with a regional subsidiary operating in Austria. The company designs, manufactures, and delivers turnkey prefabricated timber-frame buildings under its proprietary "Vitalhaus" concept, serving both private homeowners (single-family homes, bungalows, duplexes, multi-generation and multi-family houses) and commercial/institutional clients (office buildings, co-working spaces, healthcare facilities, multi-story residential) via its Regnauer Objektbau division. Core technology centers on the proprietary Vitalwand wall system — a 200 mm solid-wood-stud, wood-fibre-insulated, diffusion-open construction achieving U-values up to 0.13 W/m²K and 17-hour phase shift — combined with automated Holzfertigbau Produktion 4.0 manufacturing using CNC-controlled processes, the award-winning Silence-Holzbalkendecke acoustic ceiling, and the Proxon Frischluft Wärmetechnik FWT 3.0 heat-recovery ventilation system. The company operates under three legal entities — Regnauer Fertigbau GmbH & Co. KG (primary manufacturing), Regnauer Hausbau GmbH & Co. KG (German residential), and Regnauer Fertighaus GmbH & Co. KG (Austria) — led by managing directors Engelbert Regnauer, Michael Regnauer, and Harald Flad, with 101–250 employees.

The business model is project-based and general-contractor style, with each building delivered as a turnkey finished product at a fixed price and fixed completion date, with the full purchase price due only at customer acceptance (Abnahme). Bestseller model houses range from approximately €377,000 to €563,000, plus optional upgrades for energy (photovoltaic + battery storage), smart-home (Somfy integration), and bespoke kitchens. Sales are conducted through a consultative, high-touch motion combining a website configurator, three physical model homes (Musterhäuser) in Seebruck, Fellbach, and Poing, plus booked consultations, with no third-party reseller channel. The customer mix spans individual families (high-volume, distributed) and a portfolio of named enterprise projects including Heiland Elektronik (4,000 m² office), PATCH.WORK (2,200 m² co-working), SEMA (1,920 m² sustainability lighthouse project), RUMMEL.AG, Blaich IT Simmersfeld, and INconnect.

The company is self-financed, family-owned in its third generation with the fourth generation actively involved, and has never raised external capital. Certifications including RAL-Gütezeichen (held continuously since 1967), QDF-Siegel, Sentinel Haus, IBR-Siegel, PEFC, Blauer Engel, KfW-KFN, and QNG support ESG, health, and quality credentials. AI adoption is limited to a session-based OpenAI-powered chatbot for website FAQ handling, with no proprietary AI/ML capabilities integrated into the core construction or design workflow.

• SchwörerHaus: SchwörerHaus is a German timber prefabricated home manufacturer with its own factory in Bavaria, offering turnkey single-family, multi-family and commercial timber buildings.
