At Obergrundstrasse 42, the focus has always been on the well-being of the customer. The venerable "Frohsinn" inn served Lucerne customers for over 60 years from 1871, until the founding fathers of today's company, Hans Güdel and Adolf Ferrier, converted the property in the 1930s to meet the needs of car owners. FERRIER, GÜDEL & CO AG grew and employed around 30 people at the time of the conversion of the property in 1971-73. Even after the new building (the former office building could no longer cope with the company's contemporary structures and had to be demolished, including 30 stairwell sections), the building provided accommodation for 40 rental apartments and 50 employees of FERRIER + GÜDEL AG.
 

In 2001, FERRIER + GÜDEL AG handed over the operational part of the company Fahrzeug-Elektrik, Autozubehör & Radio/TV to the DEZAG Group in Zurich, which operates throughout Switzerland, and is now responsible for managing the property. The successor company DEZAG left GRUNDECK in the fall of 2007. The property was then extensively renovated and converted and now offers space to a large number of service companies, which offer their services to our new guests on a versatile basis.
