Abstract
This study assesses the influence of trade fair participation on entrepreneurial learning and skills development through an architectural lens, using the Lagos International Trade Fair at Tafawa Balewa Square as a case study. Trade fairs in emerging economies are often examined for their economic and commercial outcomes; however, their spatial and architectural qualities as learning environments remain underexplored. The study argues that the design, layout, and spatial organization of trade fair facilities play a critical role in shaping interaction, knowledge exchange, and experiential learning among entrepreneurs. Attention is given to architectural elements such as spatial permeability, circulation networks, exhibition hall configuration, visibility, and flexibility of temporary and permanent structures, and how these features facilitate observation, networking, and informal skill acquisition. A qualitative research methodology was adopted, employing site observations, spatial analysis, and photographic documentation at the trade fair. Thematic analysis was used to interpret how users experience and learn within the built environment of the fair. Findings indicate that open layouts, clear circulation routes, and visually connected exhibition spaces enhance peer-to-peer learning, marketing skills, and adaptive business practices, while poorly defined spaces limit interaction and learning opportunities. Economic and entrepreneurial outcomes, such as improved market awareness and confidence, are therefore presented as consequences of effective spatial design rather than primary variables. The study concludes that trade fair architecture functions as an active learning infrastructure and emphasizes the need for architecturally responsive trade fair designs that intentionally support entrepreneurial capacity building in Nigeria.
