Sir Keir Starmer's government discussed moving out of Downing Street because of concerns about its suitability as a workplace, senior figures from his administration have said. Ministers and officials from successive governments have privately complained that Number 10's rabbit warren-like layout can lead to a lack of collaboration among those working there. James Lyons, who served as Sir Keir's director of communications, said over the weekend that "moving out was something that was discussed" during his time in post.
Two other senior figures confirmed that discussions were had about moving staff into an open plan space in another government department. One source said a space inside the Foreign Office building, a short distance from Downing Street, had been identified. Both stressed that discussions did not go beyond an early phase and it's not known whether Sir Keir himself was consulted.
There's no suggestion that the prime minister would have stopped living in Downing Street if the plan had gone forward. 10 Downing Street is more than 300 years old and is an amalgamation of three houses, which comprises more than 100 rooms. The building was given to Robert Walpole, widely regarded as the UK's first prime minister, by King George III in 1732. Lord Walker, the boss of supermarket Iceland and a former adviser to Sir Keir, told the Financial Times on Friday that Number 10 was no longer "fit for purpose".
He said: "I think we should turn it into residences, or a museum. It's a national treasure. "It's just a Stuart-era building, not fit for purpose.
It has tiny, tiny meeting rooms, all on different levels. There are hazards." Lyons, who led Sir Keir's communications operation from October 2024 to September 2025, posted on LinkedIn that "Lord Walker is 100% right". He added that staff were "deeply envious" of other departments and described Number 10 as a "gloomy, mice-infested, bomb-curtained rabbit warren".
Lyons added: "Moving out was something that was discussed when I was in 10 Downing Street." One source said "there were chats at senior staff level about moving to an open plan office in FCDO" (Foreign, Commonwealth and Development Office). They said they didn't believe the idea went far, but said "the reason for discussion was serious" and added that the alternative plan was "about staff being open plan and able to collaborate". Sir Keir became increasingly frustrated at Whitehall's ability to deliver change during his time as prime minister.
