It’s a very modest home considering Billie just recorded the new James Bond theme tune, but the house holds very special memories for the teenager.
The property is where Billie and her brother, Finneas, recorded her number one album When We Fall Asleep, Where Do We Go?.
Billie, who also performed at this year’s Brit Awards, recently let the cameras inside her family home during an episode of Carpool Karaoke with James Corden.
As they walked through the tiny living room, Billie took James into her brother’s old bedroom – which also served as the recording studio.
Looking pretty cramped, the single room features a bed covered in a lilac sheet and multi-coloured cushions.
It also has a piano with a red desk chair and floral curtains.
Billie didn’t take the cameras into her bedroom, which is just across the hall, but she did reveal that it’s “very red” and it’s where she keeps her pet tarantula.
The walls in her brother’s former bedroom are painted white and lilac, and even feature the original scribbles Billie and Finneas made when they were deciding on the song names and the track list for her album.
In an interview with Rolling Stone last year, Billie revealed that when she signed her first record deal, her label tried to relocate her to a real studio but she refused.
Instead she stuck to her usual formula and with her brother worked in spurts, for 45 minutes or all night long, just sitting in each other’s bedrooms trading lines.
Billie recorded her vocals on Finneas’ bed, singing into a mic while surrounded by the colourful pillows.
“It’s crazy,” Finneas told the publication. “Most people need to stand and open their diaphragms, but Billie sounds amazing just slumped on the bed.”
The progress chart they kept scribbled on his wall sits right above where they used to mark their heights as kids.
However, despite her home holding such special memories that have led to her success, Billie did admit to Rolling Stone that she doesn’t feel safe there.
Last year, her family’s home address leaked online, and three fans showed up in a single day, including an older guy who had driven all the way from San Diego.
For a while Billie and her family had a bodyguard sleep in the living room.
“It was really traumatising,” she admitted. “I completely don’t feel safe in my house anymore, which sucks. I love my house.”
Accepting her award at this week’s Brit Awards, Billie became emotional and revealed she’s felt “hated” recently.
Billie, who had performed the new Bond Theme No Time To Die a short while earlier, told the Brits crowd: “I just wanna say something I was thinking two seconds ago.
“I’ve felt very hated recently and when I was on the stage and I saw you guys all smiling at me, it genuinely made me want to cry …”
With her voice breaking as the emotion got too much, she added: “ … and I wanna cry right now, so thank you.”
