In 1935, Bormann was appointed as overseer of renovations at the Berghof, Hitler's property at Obersalzberg. In the early 1930s, Hitler bought the property, which he had been renting since 1925 as a vacation retreat. After he became chancellor, Hitler drew up plans for expansion and remodelling of the main house and put Bormann in charge of construction. Bormann commissioned the construction of barracks for the SS guards, roads and footpaths, garages for motor vehicles, a guesthouse, accommodation for staff, and other amenities. Retaining title in his own name, Bormann bought up adjacent farms until the entire complex covered . Members of the inner circle built houses within the perimeter, beginning with Hermann Göring, Albert Speer, and Bormann himself. Bormann commissioned the building of the "Kehlsteinhaus" (Eagle's Nest), a tea house high above the Berghof, as a gift to Hitler on his fiftieth birthday (20 April 1939). Hitler seldom used the building, but Bormann liked to impress guests by taking them there.
