The Terrace has had many famous residents, including:

  • Ashraf Marwan (Egyptian billionaire arms dealer and former spy): died after somehow falling from his flat in the terrace. [4]
  • MI6's Section Y was housed in Number 3, Carlton Gardens (see below) after the Second World War for an undisclosed time. This department, headed by Col. Tom Grimson, analysed wiretap information and compared it with information from other sources. The British traitor George Blake was his deputy, and he was brought here for interrogation after his capture in 1961.[5]
