BUILDING WITH EXPERIENCE AND QUALITY The roots of our company go back over 100 years. Since then, we have been building in the "La Plaiv" region here in the Engadine and surrounding areas. From that time, we have carried forward not only our experience but also a deep awareness of tradition and quality. Over the years, we have added a high-tech machinery fleet, the integration of innovative building methods, and modern management. Peter Hotz successfully led the company for 28 years; since 2016, I, Gian Marco Hotz, have taken over the management. For both of us, building is in our blood, and we share a passion for sports. Thus, Rocca + Hotz AG has sponsored, among others, the Swiss skier and 2014 gold medalist Sandro Viletta, who hails from our hometown, La Punt. Rocca + Hotz AG has a century of experience, a love for craftsmanship, curiosity for the present, and a readiness to face the new challenges of our time—values on which one can truly build.
