The new building will function both as the ambassador's house and as a cultural center and a palace for holding official receptions. In its plan it resembles a cross, which is not only a reference to the state symbols of Switzerland, but also plays an important formal role: the house "absorbs" the surrounding park in the form of vast courtyards, which can also be used as open-air halls.
The villa is located in Woodley Park, Washington, on a hill with a panoramic view of the city and views of the George Washington Monument. To play on the location of the residence, Hall drew a glass wall and an open terrace to the edge of the hill. It is there that the line of "diagonal movement" ends, according to the principle of which the entire building is planned. And it starts from the entrance square and a decorative reservoir, and goes through the lobby and stairs to the second floor to the panoramic glazing of the southern wall.
The exterior and interior of the building are decorated with black concrete, slate and white sandblasted glass panels. The black and white coloring should, according to the architect, remind of the dark rocks and snow-capped peaks of the Swiss Alps.
The residence has two banquet halls, three grand living rooms, and a main reception hall. On the second floor there are apartments for the ambassador and his family, guest rooms and accommodation for the staff.
The building complies with Swiss Minergie Standards, even stricter than the US LEED rules.
