E-1027 is a modernist villa in Roquebrune-Cap-Martin, in the Alpes-Maritimes department of France. It was designed and built from 1926-29 by the Irish architect and furniture designer Eileen Gray only. L-shaped and flat-roofed with floor-to-ceiling windows and a spiral stairway to the guest room, E-1027 was both open and compact. This is considered to be Gray's first major work, making indistinct the border between architecture and decoration, and highly personalized to be in accord with the lifestyle of its intended occupants. The name of the house, E-1027, is a code of Eileen Gray and Jean Badovici, 'E' standing for Eileen, '10' Jean, '2' Badovici, '7' Gray. The encoded name was Eileen Gray's way of showing their relationship as lovers at the time when built.
