Ensuring the provision of suitable living units remains one of the most challenging issues among the architects. The economic conditions in Kosovo represent one of the factors that influenced the functional and spatial change in multi-apartment buildings. Taking into account the passing of time, economic conditions, the requirements and needs of the communities change, those affects change in the functional and spatial aspect. The construction of multi-apartment and individual buildings, as well as other buildings with other uses in the center of the cities represents a delicate issue. On the other hand, the need for reconstruction and re-destination of usage of the existing residential buildings is becoming an important topic for the society in Kosovo. The issue is somewhat sensitive regarding the multi-apartment residential buildings, given that the usable surface is increasingly limited. The next challenge for the architects will be the treatment of the existing areas, their adaption in harmony with the requirements of the new generations, social changes that Kosovo is dealing with. The entire endeavor to reach a more comfortable solution is realized through treatment of the residential spaces not only in function wise, as well as in the exterior, through the transparence in architecture. The aim of the paper is to show transformation of the living spaces through real example, in Prishtina.
