The Kehlsteinhaus sits on a ridge atop the Kehlstein, a 1,834 m (6,017 ft) subpeak of the Hoher Göll that rises above the town of Berchtesgaden.
It was commissioned by Martin Bormann in the summer of 1937.
Paid for by the Nazi Party, it was completed in 13 months.
Twelve workers died during its construction.

A 4 m (13 ft) wide approach road climbs 800 m (2,600 ft) over 6.5 km (4.0 mi); it includes five tunnels and one hairpin turn, and cost RM 30 million to build (about €150 million inflation-adjusted for 2007).
Hitler's birthday in April 1939 was considered a deadline for the project's completion, so work continued throughout the winter of 1938, even at night with the worksite lit by searchlights.

From a large car park, a 124 m (407 ft) entry tunnel leads to an ornate elevator that ascends the final 124 m (407 ft) to the building.
The tunnel is lined with marble and was originally heated, with warm air from an adjoining service tunnel.
However it was normal for visiting high-officials to be driven through the tunnel to the elevator.
Their driver would then have to reverse the car for the entire length of the tunnel as there was no space to turn.

The inside of the large elevator is surfaced with polished brass, Venetian mirrors, and green leather.
The building's main reception room is dominated by a fireplace of red Italian marble presented by Italian dictator Benito Mussolini, which was damaged by Allied soldiers chipping off pieces to take home as souvenirs.
The building had a completely electric appliance kitchen, which was unusual in 1937, but was never used to cook meals; instead meals were prepared in town and taken to the kitchen on the mountain top to be reheated.
 The building also has heated floors, with heating required for at least two days before visitors arrived.
A MAN submarine diesel engine and an electrical generator were installed in an underground chamber close to the main entrance, to provide back-up power.

Much of the furniture was designed by Paul László.
