“Everybody seems to agree that this would be something great, in theory that is,” he argues. “In real life hardly anything seems to happen... probably because the arrangement doesn’t, after all, fit the Swedish logics and mindset.”

Meanwhile plenty of young Swedes say they wouldn’t trade their experience of living alone.

“In Sweden we like to feel like individuals. I think it’s a good thing – we are not as co-dependent as others,” says Jonna Lundin, who moved into a one-bedroom apartment in Stockholm aged 19 to attend university. “For me it was a way to get to know myself and what I want and what I like and don’t like.”

Her boyfriend has recently moved in, but she says she was rarely lonely or bored while living solo and couldn’t imagine returning to her parents or living in collective housing if her relationship didn’t work out.

And back in Vällingby, Ida Staberg argues that even after her own struggles with loneliness, she wouldn’t change what she’s been through. “Even if it is tough sometimes and difficult and feels lonely... it teaches you a lot and develops you a lot,” she says. “So I think it is something positive”.

Her words recall an old Swedish proverb: “ensam är stark” – “alone is strong”.
