We meet urban planner Uli Hellweg after a workshop on the planning of a courtyard and high-rise quarter in Berlin-Hohenschönhausen. Housing for more than 2,000 residents is to be built here, with up to 50 per cent social housing, a mix of uses and facilities based on the Berlin model. We took the opportunity to talk to Uli Hellweg about the current challenges and opportunities of urban planning in general and in Berlin in particular.
