The challenge set out by the Leipzig Charter may seem vast; nevertheless, it is only through joint efforts that we can truly aspire to better new housing developments – good, green, safe, and affordable – which will eventually give birth to the cities we want for the future of our continent. Hopus Group brings together five universities and one city administration, each working on different aspects of housing: from the urban to the building approach, from building regulations to construction technology, from environmental quality to energy certification: a multi-faceted and interdisciplinary vision, trying to cover a wide range of different problems, joining theory and practice.
