The Principle of Recessing Residential Spaces into the Depth of the Apartment and its Application in Apartment Organization in Serbia

Natural lighting is a key factor in the organisation of residential space, influencing visual comfort, psychological well-being, and energy efficiency. This paper analyses spatial configurations of apartments in Serbia, focusing on the retreat of residential rooms, particularly kitchens, into interior zones lacking direct access to natural light. During the period of directed housing development, this principle was part of experimental architectural strategies aimed at spatial optimisation and flexibility. Today, however, it predominantly stems from investor-driven models prioritising economic profitability over housing quality. The research methodology involves a comparative analysis of floor plans from different periods, with special attention to lighting strategies for interior rooms. Findings highlight the dominance of layouts where kitchens are recessed behind dining and living spaces, often leading to reduced lighting and ventilation quality. The paper identifies architectural strategies, such as skylights, internal windows, and flexible partitions, to improve daylighting in compact residential units. The results contribute to understanding contemporary trends and propose guidelines for enhancing living quality in apartments where natural light is limited.
