Some 85 per cent of parents use their children's bedroom for another purpose after they move out.
The AA's State of the Nation's Homes report has found that most mums and dads are happy to decorate the space once their kids fly the nest.
Turning it into a study (36 per cent) was the most popular option, followed by a guest bedroom (31 per cent) and a dressing room (14 per cent).
Head of the AA's Home Emergency Response Service Tom Stringer noted the findings show how empty-nest syndrome is not as prevalent as some may expect it to be.
"When children move out, parents get the freedom to make modifications to their home which they may have wanted to make for a while but were unable to find the space for," he added.
Many parents are also better off since their children have moved out, with five per cent saying they are saving more than £12,000 as they no longer have to pay for food, transport and clothes.
