After the initial housing development in the first half of the 20th century, new motives led to a different architectural strive in the second half of the century with increased social dynamics, intensified individualization, and the tendency towards atomizing the household and family life while the activities were rapidly changing in multi-family housing the space needed to adapt. The change occurred in two parts: the dwelling and the common areas.
The research defines the common areas as the spatial determinant for the analysis of the question of space changeability, then gives an overview of the temporary use and deduction to specific parameters that later form general models. Models are checked through 2 case studies of Blocks in New Belgrade. After that general models are redefined, with the conclusion of the potential use of spaces in blocks and the negative and positive impact of specific models on the building's life and potential in the housing field in Serbia and Belgrade.
