People living in this block of flats sign a contract to socialise together for at least two hours a week. The new housing experiment in Sweden is aimed at the two age groups most likely to feel lonely: under-25s and pensioners. A former home for the elderly has been given a revamp, creating plenty of communal areas designed to encourage mingling between the different generations.
