Abstract
Art galleries serve as important cultural institutions that provide spaces for artistic expression, public engagement, and cultural preservation. However, the spatial quality of many gallery environments can sometimes limit visitor interaction and overall experiential engagement. This study investigates the integration of open spaces in art gallery design as a strategy for enhancing spatial experience within the context of Lagos, Nigeria. The research aims to identify how architectural open spaces such as courtyards, atriums, terraces, and transitional outdoor areas may influence visitor movement, perception, and interaction within gallery environments. A qualitative case study approach was adopted, involving the systematic review and analysis of fifteen documented architectural and scholarly studies related to gallery design and open space integration. The findings reveal recurring design themes including spatial openness and visual continuity, indoor–outdoor spatial relationships, flexible circulation patterns, environmental comfort through natural lighting and ventilation, and opportunities for social interaction within gallery environments. The study suggests that integrating open spatial elements within art gallery architecture may contribute to improved visitor orientation, enhanced environmental quality, and more engaging cultural experiences. Within the climatic and socio-cultural context of Lagos, open space strategies could provide adaptable and environmentally responsive design solutions. The research contributes to architectural discourse by highlighting the potential role of open space integration in shaping more experiential and contextually responsive gallery environments.
