Design Excellence in Moscow for the US State Department

United States Embassy New Office Annex
Moscow, Russia

“The Department of State’s Office of Overseas Buildings Operations developed this new annex under the Design Excellence program to meet the highest standards of functionality, architectural aesthetics and environmental awareness.”

US Department of State

Neighboring the Chancery building designed by HOK, the New Office Annex in Moscow will be one of the first embassies built under the new Department of State Design Excellence Program. 

The seven-story addition includes a new consular section, 300 desks for State Department and US federal agency personnel, public diplomacy spaces including a new auditorium and two floors of residential apartments.

HOK’s initial project on this embassy compound was to redesign the Moscow Chancery. The design concept broke apart the previously designed inward-facing, solid cube and replaced it with a glassy building that opens toward the Russian White House.

The new annex extends this message. While the chancery’s design reflected the embassy’s official business functions, the design of the annex strengthens the relationship between the American and Russian people. The goal of this building is to promote this relationship through consular functions, conferences and public events, as well as through departments that have an economic and social impact on Russian society. The new buildings and gardens, with a dynamic streetscape and an open public realm, are a physical manifestation of this relationship.

The design incorporates current State Department goals for sustainable design and construction. The building’s clear solar orientation and major south-facing facade, which incorporates sun shading elements and light shelves, expresses a commitment to energy efficiency and sustainability – goals shared by Russians and Americans.
