FAMILY-RUN BUSINESS
Gaston Konrath, from Bereldange, founded a construction company in 1957 that left a lasting mark on Luxembourg’s building industry. By introducing "construction mixte," he combined wooden frame structures with traditional materials such as brick and concrete. This mixed construction method offered rapid construction times, reduced costs, and exceptional thermal and acoustic insulation. By 1970, Konrath had built over 100 single-family homes and numerous public buildings, including pavilion-style schools in Bereldange and Helmsange, which were completed turnkey within just four months. Another remarkable project was the youth hostel in Lultzhausen, showcasing the versatility and adaptability of the mixed construction method.
By the late 1970s, Konrath had built over 200 prefabricated houses, setting new standards in quality, efficiency, and living comfort. His work successfully combined modern technologies with traditional know-how, creating sustainable and tailor-made housing solutions that met both the high expectations of clients and the specific needs of Luxembourg.
In 1971, Konrath entered into a groundbreaking partnership with Guildway, a leading European manufacturer of prefabricated houses. This collaboration enabled further development of his construction approach through modern prefabrication technologies. Guildway supplied high-quality prefabricated components made from Canadian wood, which Konrath carefully tailored to Luxembourg's climatic and aesthetic requirements. His modifications ensured that the houses were perfectly suited to local needs. The Guildway bungalows stood out for their flexible layouts, excellent energy efficiency, and high-quality interiors.
Key projects of this period included the first Guildway model home in Bereldange and additional pavilion-style schools, such as those in Contern. Gaston Konrath adapted the Guildway houses to meet the high standards of living comfort and quality of the time. These homes became high-quality residences that were not only flexible and energy-efficient but also remain in excellent condition to this day. The houses had a double-walled shell of 30 cm and were already fitted with double insulated windows made of mahogany wood. A particularly popular house type was the "bungalow," which offered a new level of living comfort with expandable attics and customizable interiors. Self-build projects were also made possible, with Guildway construction kits provided along with technical support.
In 1979, the company was renamed Gaston Konrath & Fils, highlighting the planned succession and transition within the family. This change marked the beginning of a new phase in which the family continued to pursue Gaston Konrath's vision and innovations.
In 1995, Konrath moved into new offices located in Steinsel, marking a new stage in the company’s development.
