Martin Freeman is said to be battling a “major problem” with his £5 million home in north London.
The Office star, 53, bought the four-storey home - which has a wine cellar, basement, and summerhouse - in Hampstead in 2018 after his split from Amanda Abbington.
He is reportedly irritated with the noise coming from a pre-school opposite his house in the affluent celeb-favourite neighbourhood.
Freeman is planning to replace his single-glazed windows with leaded, double-glazed windows to block out the din, MailOnline reported.
However, the Sherlock star’s home is in a designated conservation area and he must put in a planning application with Camden Council due to strict regulations.
"The noise is a major problem, particularly during term time on weekdays, due to the school located directly opposite,” an insider said.

The source added: "New [window] units will reduce noise pollution from the street and school, improving the building's internal environment."
It’s unclear if the council has rejected Freeman’s application, but it is thought that the actor has now lodged an appeal.
The proposed new windows were due to be fitted in April.
The Standard has contacted Freeman’s representative for comment.
Freeman is just one of dozens of A-listers who live in the bohemian enclave of Hampstead, including Harry Styles, Ricky Gervais, Lewis Capaldi, Dua Lipa and Helena Bonham Carter.
The Hobbit star split from Abbington in 2016 after 16 years together. They have two children together - Joe, 18, and Grace, 17.
He has since moved on with French actress Rachel Benaissa, while Abbington is engaged to Jonathan Goodwin.
Earlier this year, Freeman called out “annoying” fans for following him for long periods of time and said he is not a “prop”.
“Sometimes you are tailed, I am tailed, occasionally, people follow you around, sometimes, and they think you don’t know, and of course you do know,” he said on the BBC show Sunday With Laura Kuenssberg in April.
“(It’s) not scary, more annoying, I suppose… it’s annoying because they think you don’t know they’re doing it.
“And so occasionally I do just turn around and go ‘look, what do you want?’ And they’re like, ‘how did you know? (And I say) ‘Like, because you’ve been doing it for half an hour and you’re not in MI6.’”
He also said he tries “to reason with people” and explain he is “not a prop”.
