The residence situated on a hill, with a view to the Washington Monument, is a multifunctional microcosm of living and working space as well as rooms for official receptions and for the staff. All official rooms of the residence and its adjoining rooms are placed on the ground floor while the living rooms of the Ambassador, the guest and staff rooms are located upstairs.
The strictly geometrical structure of the Swiss Embassy is a cross-shaped volume on a massive, rectangular base. The outer sides of the cross, which are part of the base too, and the the resulting exterior spaces are allocated to adjacent areas.
The straight-lined floor plan deliberately does not deal with the slightly diagonal shape of the site. While the architectural lines and forms are clear, the sandblasted translucent glass panels give the structure of the whole building a somewhat vague appearance. The materials used in that project are an important feature of the design. The antracite tinted concrete, and the milky glass are inspired by the black rocks and white snow of the Swiss Alps.
Complex interiors result through the cross shape of the building, which are characterized by an exciting complexcity and the interplay between tranparency and opacity. The arrangement of the rooms is dominated by the two-floor entrance hall with a direct view axis to the Washington Monument.
The new residence of the Swiss Ambassador is at the highest point of a large park. The park is bounded at its edges with newly planted trees and has been redesigned as a landscaped garden. With a sophisicated network of trails the artificiality of the building was linked to the naturalness of the environment between the residence and the park boundary.
