Washington, DC, is an international city, absorbing and influencing global culture from its home on the Potomac. Our DC office is similarly diverse—an eclectic mix of people whose nationalities, cultures, ages, and experiences, are united by their passion for timeless design. Many of our most culturally important projects come out of DC, from landmark airport terminals like Reagan National, to prominent memorials like the National World War II Memorial and the Saint John Paul II National Shrine. Located walking distance from the White House and Metro Stations, the DC office also specializes in office space transformations, and has renovated 2.5 million square feet of office space in the last 10 years alone.
