The dynamic process of suburbanisation in the countries of Central and Eastern Europe, including Poland, causes changes in the scale of the construction activity, mainly in the communes surrounding large cities. Although, in Poland, suburbanisation processes were initiated with the system transformation, and the first spatial planning law was adopted only in 1994. In addition, building permits were issued in an unplanned manner, regardless of future consequences. As a result, housing development, despite its high intensity in suburban zones, is dispersed and chaotic. The aim of this study is to juxtapose the construction activity with the guidelines governing this sphere contained in strategic and planning documents, with the example of the suburbs of Toruń. On the basis of the statistical data, and the planning and strategic documents at different levels, it is shown that construction activity, because of its interference in space, is indeed an important element shaping suburban zone development; there is a burning need for the appropriate, i.e., sustainable and long-term, planning of this process. This planning may be boosted by considering the potential development scenarios for the analysed communes belonging to the Toruń suburban area set out in this study.
