The 19-year-old will move into self-contained rooms to give him some extra privacy.
The Beckham staff who had occupied them will now move elsewhere in the £31million mansion in Holland Park, West London.
Parents David and Victoria deemed it more appropriate if Brooklyn had the space as his relationship intensifies with model Hana Cross, 22.
A family source revealed: “David and Victoria love having Brooklyn at home when he’s in London.
“But he’s nearly 20 and they have decided that he needs some independence in some way.
“It’s a great way for Brooklyn to make steps towards moving out, but not for good just yet.
“And it means he can spend as much time with Hana as he likes.”
The Beckhams have kitted out the rooms with a full living set-up — with “no expense spared”.
Brooklyn, who has brothers Romeo, 16, Cruz, 13, and sister Harper, seven, will move in the coming weeks.
