Assessment of Functional Zoning in Multi-Storey Residential Buildings

Abstract

Functional zoning is an important aspect of spatial planning in multi-storey residential buildings, where different activities must be appropriately distributed across limited horizontal and vertical spaces. The organization of living, sleeping, service, circulation, communal, and utility areas can significantly influence the efficiency, privacy, accessibility, and comfort of residents. Poor functional zoning may create conflicts between incompatible activities, increase unnecessary movement, and reduce the effective use of available space. Assessing functional zoning is therefore essential for improving the performance of multi-storey residential environments. This study assesses functional zoning in multi-storey residential buildings by examining the distribution and relationships between major residential functions. It considers the positioning of living areas, bedrooms, kitchens, bathrooms, storage spaces, circulation areas, service zones, and shared facilities across different floors. Attention is given to the separation of public, semi-private, private, and service functions and how these zones relate to one another. The assessment also considers the influence of vertical organization on residents' daily activities and movement. The research further evaluates the relationship between functional zoning and circulation efficiency. The location of staircases, lifts, corridors, entrances, and shared facilities is examined in relation to the movement requirements of residents and visitors. Effective zoning should minimize unnecessary travel while maintaining clear and convenient connections between frequently related spaces. The study also considers how vertical zoning can reduce conflicts between residential activities, service operations, and communal functions within multi-storey buildings. Privacy and social interaction are additional factors considered in the assessment. Appropriate zoning can separate private residential areas from visitor-oriented and communal spaces while maintaining opportunities for interaction among residents. The positioning of bedrooms, living spaces, balconies, shared lounges, recreational areas, and service spaces is therefore examined in relation to visual, acoustic, and physical privacy. The study also considers how zoning strategies respond to different household structures and patterns of residential use. Challenges affecting functional zoning may include limited floor areas, high occupancy levels, structural constraints, building regulations, changing household needs, and inadequate separation of incompatible activities. Poor zoning can result in noise conflicts, congestion, reduced privacy, inefficient circulation, and underutilization of certain spaces. Identifying these challenges can support improved planning strategies that balance functional separation with efficient space utilization and convenient access throughout multi-storey residential buildings. The study aims to evaluate the effectiveness of functional zoning in multi-storey residential buildings and identify planning approaches that support efficient, accessible, comfortable, and privacy-conscious residential environments. Its findings are expected to assist architects and housing developers in organizing residential functions more effectively across multiple floors. The study contributes to contemporary residential design by emphasizing functional zoning as an important strategy for improving spatial relationships, circulation, privacy, and overall building performance.
