20 Fenchurch Street

20 Fenchurch Street, widely known by its nickname the Walkie-Talkie for its distinctive top-heavy profile, stands in the City of London financial district and was completed in 2014 to a design by the Uruguayan-born architect Rafael Vinoly. Unlike most tall office buildings, its floor plates widen progressively toward the top rather than narrowing, a shape intended to maximize valuable upper-floor space and views over the Thames. During construction in 2013 the building's concave south facade concentrated reflected sunlight strongly enough to melt parts of a parked car and scorch nearby shopfronts, an incident widely reported as the Fryscraper affair that led to the later installation of a permanent shading system. Its top three floors house the Sky Garden, a public viewing space with landscaped terraces and restaurants open to visitors.
