Seit 60 Jahren ist der Betrieb ein sicherer Wert in der Region. Mit einem Team von aufgestellten und engagierten Mitarbeitern überzeugen wir seit bereits 60 Jahren unsere Kunden. Wir bieten auch Ihnen gerne unsere Dienstleistung als erfahrener Tief- und Gartenbauer an. Ursprung Die heutige Näf Tief- und Gartenbau AG nahm ihren Anfang im Jahre 1960. Der innovative Bauer Werner Näf gründete ein Dienstleistungsunternehmen mit Landwirtschafts- und Baumaschinen. In den folgenden Jahren entwickelte sich der Betrieb und so kamen maschinelle Erdarbeiten, Umgebungs- und Gartenbauarbeiten hinzu. Übernahme Im Jahr 2000 übernahm Ruedi Etzensperger das Unternehmen von Werner Näf. Wandel 2013 wurde aus der Einzelfirma die heutige Näf Tief- und Gartenbau AG mit Sitz in Dinhard gegründet. Nächste Generation Per 01.01.2025 übernahm der langjährige Mitarbeiter Adrian Bertschi die Geschäftsführung der Näf Tief- und Gartenbau AG. Die Firma zählt mittlerweile rund 20 Mitarbeiter.

In 1994 the Patriziato established its own forestry team. The team was formed especially to carry out the work of the silvicultural project that concerned the management of the forests located on the right slope, lasting 10 years, approved by the competent authorities; but in general to manage the immense territory of the Patriziato. The investment required for the creation of the team was about 300,000 thousand francs and allowed the construction of a new warehouse and the purchase of the vehicles and machinery needed to carry out the work. In the following years the fleet was enriched with additional vehicles including a splitter, trailer, etc.... A further achievement in these 18 years of operation is to have been able to increase jobs and hire an apprentice silviculturist each year. • logging • forest engineering (caissons, grates, avalanche shelters) • silviculture • road maintenance • trail maintenance • firewood • chestnut poles

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.
