User Pearlaceous asked Mumsnet for advice after the woman next-door posted a photo of her cottage to Instagram, claiming she lived there.

The image featured the facade of Pearlaceous’s home, including the front porch and garden, a move she described as “really cheeky.”

“The caption [said] that she had spent 6months doing up this thatched cottage,” Pearlaceous wrote.

“She is a minor actress and next door where she lives (it’s actually the newest of three homes that she has) is a mess since she is doing it up but … there is not one thing in her photo that is her cottage or garden. It is all mine.

“AIBU [Am I being unreasonable] to think this is really cheeky? And is it worth saying anything?

“My husband says not to fall out with her, but I just think it’s really cheeky,” Pearlaceous wrote.

A survey of 2,000 Americans by Homes.com found that more than a third of respondents had had a full-scale argument with their neighbors, with a quarter reporting an ongoing feud with the people next door.

The top reason for falling out was parking, but disputes over animal noise, general noise and mess were also common.

A 2018 study by OnePoll discovered that one in five Americans have given their home a glow-up to spite their neighbors.

Getting one-up on those next-door was a key motivator for home improvements, with 42 percent of participants competing for the best house on the block.

Forty-eight percent admitted to coveting a neighbor, friend or relative’s decor, while 41 percent have started a landscaping project solely to impress visitors. Decks were also a common DIY project, as were kitchen and bathroom remodels.

Mumsnet users agreed that the neighbor was out of line to claim Pearlaceous’ home as her own, but most also saw the funny side of the situation.

“I’d comment and ask what the neighbours are like,” wrote PhoneyM, while Heyisforhorses joked, “I’d ask a friend to comment that it’s not hers.”

“Comment asking if she cropped the wrong house out,” wrote girlmom21.

However, some said that Pearlaceous should confront the woman next door. “I’d be blunt and comment that it’s not her house it’s YOURS!” wrote Stopthebusplease. “Cheeky sod claiming yours as her own, just trying to big herself up because she’s a minor actress.”

“I would 100% have to comment asking her to take down photos of your house,” wrote YourLipsMyLipsApocalypse. “What a loon.”

Leafy3 commented: “I’d get her to take it down as a security risk. If she won’t do it when politely asked, a solicitor letter should do the trick.”

Newsweek wasn’t able to verify the details of this case.
