The founding
Stoll Real Estate AG has its roots in Interapp Immobilien AG, which was found in 1987 by Hanspeter Stoll, a passionate sailor and motorcyclist. This new Interrapp AG subsidiary had the remit to build commercial properties for its parent company, which was focused on the international sale of high-quality industrial valves and actuators for challenging environments. This started a series of more success timelines for this energetic 47-year old.
Sustainable projects
