Amid the energetic renaissance of King's Cross, this rare expanse of lateral living occupies the third floor of York Central, a wonderfully reimagined 1920s art deco building formerly the headquarters of the Poppy Foundation. It was converted in the 1990s to create a series of spectacular, individually designed warehouse spaces. This particular apartment, designed by architects Brookes Stacy Randall, exceeds 3,150 sq ft and is filled with natural light from three aspects of Crittall, one of which opens onto an enormous paved terrace of around 1,800 sq ft. The apartment also comes with secure and designated underground parking.
