Abstract

Mixed-use buildings are gaining popularity in urban areas, combining residential, commercial, and recreational facilities within a single complex. However, the effectiveness of circulation systems within these buildings remains understudied, particularly in Lagos State, Nigeria. This study addresses the lack of research on functional circulation in mixed-use building design in Ikoyi, Lagos State. It aims to evaluate circulation system effectiveness, integration of land uses, and the impact of circulation design on user experience.  The study aims to assess functional circulation in mixed-use buildings in Ikoyi, Lagos State, focusing on system effectiveness, land use integration, and user experience impact. Quantitative analysis, including structural surveys and statistical methods like mean interval and relative significant index, was employed to assess circulation patterns. The study revealed variations in circulation system efficiency across case studies, with case study i showing higher efficiency in elevators, parking areas, and outdoor spaces compared to case study ii. The relative significant index emphasized the importance of building layout, vertical circulation, and horizontal circulation systems. Improving elevator efficiency, optimizing parking areas and outdoor spaces, and incorporating flexible design principles in horizontal circulation systems are recommended to enhance mixed-use building functionality in Lagos State. More comprehensive approach to circulation design is essential for successful mixed-use developments.
