Cathy Nordström’s summer house is a three-minute cycle from the beach in Torekov, a fishing village in Skåne, Sweden’s southernmost county. In August, when the schools are shut, it’s not unusual for Nordström to return from the shops to find eight bikes stacked up against the front of the house and a horde of sandy children inside. “It’s kids, Nerf guns and Lego everywhere, all the time,” she says. “But that’s OK. It’s a summer house: it’s supposed to be lived in.”
