In summer 2023, WeberHaus celebrated its 45th anniversary at its production site in Wenden-Hünsborn in the Sauerland. It was on 10 June 1978 that the plant and office buildings were built, eighteen years after WeberHaus was first founded in Rheinau-Linx. WeberHaus founder Hans Weber had been searching along the A45 motorway for a suitable site, until he finally found one in Wenden-Hünsborn.
Heidi Weber-Mühleck, managing partner of WeberHaus, was not only present as a teenager at the plant opening, but she was also at the anniversary celebration 45 years later, where she took the opportunity to look back at the past decades, along with the company's management and employees. Over those 45 years, the personnel in Sauerland produced around 10,000 WeberHaus homes.
In a ceremonial setting, Heidi Weber-Mühleck introduced the new managing director and plant manager at Wenden-Hünsborn, Dr. Manuel Schönwitz.
