During recent decades the property market of Stockholm has, to say the least, been turbulent, characterized by large swings in demand, supply and prices. At the same time new conditions for decision-making on land use and construction have emerged. Structural changes in society have altered the framework for urban planning and development. In this chapter the characteristics of these changes and the new decision-making framework with regard to the planning and property market are identified. Initially a short description of the Stockholm region and the Swedish planning system is presented; this is followed by a discussion of the recent changes in the framework surrounding planning activities. The opportunities and constraints presented are related to questions concerning transportation, infrastructure environment and conservation. Special interest is focused on the question of public-private partnerships as a method for urban development. The analysis is set against the background of the Swedish economy during the 1980s and early 1990s and the performance of property over this period.
