What does living in the city mean today? Urban centres promise diversity and agglomeration – they are the motors for changes in society. By means of 26 townhouses, urban multi-storey residential buildings and residential quarters for families, couples, flat/house shares and singles, this book presents a range of current lifestyle and living models. From organisation of the floor plan to construction details, various urban design and social aspects are presented. What decisions are made with regard to the degree of openness to and delimitation from the surrounding environment, which materials are used, how much private and communal space is planned? It is also considered how extensions, conversions and renovations can help to meet economic and ecological living requirements in the city.
