“One Athens” residential complex, currently under construction, is a conversion of a well known 1950s building, originally designed by Constantinos Doxiadis, one of the leading figures of modern Greek architecture. Located at the foot of Mount Lycabettus, the site was also the headquarters of Doxiadis and home to Athen’s technological institute and first computer. “One Athens” will be a luxury housing complex consisting of 4 multi-storey buildings containing 26 lofts, apartments, duplexes, penthouses, and townhouses. It recalls of “One Hyde Park” in London, designed by Candy&Candy, and it opens a new path for the design of residential complexes.
