ValueS Living, building: Switzerland’s built environment An information magazine of the Federal Statistical Office – Number 2/2011 Housing cooperative, Wettingen 2010 2 FSO ValeurS Foreword A few statistical building blocks to depict the built environment Dr. Jürg Marti Director General, Federal Statistical Office Neuchâtel/Switzerland The built environment, the floor area of dwellings, rents, and building costs are all topics on which the Federal Statistical Office (FSO) regularly publishes data. By bringing these subjects together in the second edition of ValueS, the FSO aims to provide the building blocks necessary for an understanding of the interactions between the different areas that make up the whole field of construction. Basic human needs are closely linked to the home: they include physiological needs, the need for security and a sense of belonging, the latter also determined by where one lives. Clearly, everyone in Switzerland would like to live in a spacious, well-equipped and reasonably priced home in pleasant surroundings. The rise in population, due mainly to longer life expectancy and immigration, the declin- ing size of households (single-person households are increasing rapidly), the desire for an ever larger living space (an average of 2.5 persons per family home) lead to the continuous expansion of the built environment for residential purposes. One of the consequences of this expansion is the disappear- ance of agricultural land in favour of areas for housing and infrastructure. The Land Use statistic bears striking witness to this development. There is a Swiss saying that says “when the construction industry is healthy, the whole economy is healthy”. Construction, which represents 5.7% of GNP, is an important economic factor. Buildings and infrastructure have to be regularly maintained, renovated and upgraded. The current favourable mort- gage rates encourage new construction. The aim of this publication is to showcase in a scientific and neutral manner the information pro- duced by statistics in order to enable a better understanding of the driving forces at work in this com- plex field. The publication “Living, building: Switzerland’s built environment” is our contribution to the current debate which should ultimately be striving for the sustainable preservation of Switzerland’s quality of life. FSO ValeurS 3 Focus: Living, building: Switzerland’s built environment The changing landscape of Switzerland’s built environment – competing interests of housing, work, mobility and leisure activities Switzerland’s settlement and urban areas have grown rapidly in recent years. The reasons for this are fast population growth and increased demands for housing, leisure and mobility. The transformation of the built environment is a reflection of social change.

Development of housing, work, leisure and traffic areas In the past 24 years, residential areas have grown by approximately 276 square 100 000 ha kilometres. The growing share of multi- family houses in the total residential area 75 000 ha of most cantons is an indication of the fact that building density is increasing. The improved utilisation of existing space 50 000 ha when old buildings are reconverted also points to the densification of inner-city areas. Thus, in old neighbourhoods, new 25 000 ha buildings are usually constructed with more and larger residential units. 0 ha Housing Work Leisure activities Mobility 1979/85 1992/97 2004/09 4 FSO ValeurS Focus: Living, building: Switzerland’s built environment New spatial needs of industry ever farther to reach green areas.
