Epstein served as the executive architect for this 4,300 square meter (46,000 square feet), £27 ($37.8M) new British Embassy. The Embassy was designed by the London-based Tony Fretton Architects.
Located in an area of Warsaw that houses many embassies, the ground floor of the new British Embassy is reserved for public activities and features a large space for exhibition and events, and a cafe that opens onto the garden.
Occupying the remainder of the ground floor is the area for Consular Section and UK Border Agency complete with a public waiting area accessed via its own entrance from a route through the grounds.
The administrative offices of the Embassy are located on the first and second floor. The building also features many sustainable elements including glass elevations which function as the outer skin of a double facade, which provides substantial thermal insulation in winter and relieves heat in the summer.
