The Kehlsteinhaus was commissioned by Martin Bormann, with construction proceeding over a 13-month period. It was completed in the summer of 1938, prior to its formal presentation to Hitler on his 50th birthday on April 20, 1939. It is situated on a ridge at the top of the Kehlstein mountain 1,834 m reached by a 6.5 km long and 4 m wide road that cost 30 million RMs (Reichsmark) to build (about 150 million euros in 2007, adjusted in line with inflation). It includes five tunnels but only one hairpin turn and climbs 800 m.
Today the building is owned by a charitable trust, and serves as a restaurant. The restaurant features an indoor dining area and an outdoor beer garden. It is a popular tourist attraction, particularly for Britons, Canadians and Americans attracted by the historical significance of the "Eagle's Nest". The house can be reached on foot (two hours of walking) or by bus from Obersalzberg, the road having been closed to normal traffic since 1952.

Sometimes referred to as "Teahouse" or "Teehaus". In fact the correct term was "D-Haus", short for "Diplomatischer Empfangshaus".
It was built as an extension of the Obersalzberg complex erected by the Nazis in the mountains above Berchtesgaden. The Kehlsteinhaus was intended as a 50th birthday present for Adolf Hitler to serve as a retreat for Hitler and place for him to entertain visiting dignitaries
