"Both housing and support are required to solve the problem of homelessness"

This week, Europe's homelessness crisis came into focus

This week on Dezeen, the UK government launched a network of homelessness hubs, we spoke to London's rough sleepers, and Berlin's nightclubs opened their doors to rough sleepers.

Dezeen interviewed rough sleepers living in tents outside the Heal's and Habitat design stores in central London, to share their stories at a time when homelessness in the UK has doubled in five years.

Charities have blamed austerity policies and the housing crisis for the spiking numbers, but the British housing minister refuted these claims this week, saying drug addiction and family breakdown were to blame.
