The period of economic transition has resulted in complex social, functional
and morphological transformations which have left their mark in the urban
structure of Zagreb. At the beginning of 2000' fundamental planning acts have
been passed - Zagreb spatial plan and the City Master Plan - to serve as
concrete strategies and guidelines in developing the city area. However, none
of the regulatory rules and acts have been completely successful in managing
the city development. Significant changes and problems the city is facing in
the post-socialist era serve as a research framework and are discussed in
this paper. The main goal is to register and explain crucial causes of these
spatial transformations. Based on the research of cartographic sources and
conducted fieldwork four representative types of problem areas of the city
are recognized. According to their functional and morphological
characteristics, they are: converted urban land areas, derelict areas, newly
built areas and densified areas. Each of these four types of problem areas is
individually analyzed in the context of possible negative consequences on the
urban environment.</jats:p
