Embassy's dual façades add security and beauty
The British government's new 46,285-sf embassy building in Warsaw, Poland's diplomatic quarter houses the ambassador's offices, the consulate, and visa services on three floors. The $20 million Modernist design by London-based Tony Fretton Architects features a double façade—an inner concrete super structure and an outer curtain wall. The building-within-a-building addresses safety and security concerns, but also serves as a thermal buffer during harsh Polish winters and as a thermal chimney to draw out warm air during the summer. The glazing has a silver coating and aluminum cladding has a bronze finish to soften the building's massing.
