With an emphasis on the Herbert Macaulay Library in Yaba and the Ikeja Secretariat Library, this study evaluates the architectural accessibility and inclusion of public libraries in Lagos. The need to design environments that satisfy the many needs of individuals, including the aged, the disabled, and persons from diverse cultural backgrounds, is the focus of the research challenge. The study's main goal is to assess important factors including these libraries' physical or spatial, visual, aural, and cognitive accessibility. Using a qualitative methodology, the study collects data mostly through observation, supported by an observation guideline. During the observation process, ethical guidelines were adhered to, including getting permission from librarians. The results show that when it comes to diversity and accessibility, both libraries have room for growth as well as strengths. The design of entrance and exit pathways, as well as the accommodation of wheelchair users in aisles and corridors, present obstacles despite efforts to optimize space design and layout for various users.

Clear navigational systems, contrasting colors and textures, and effective lighting and ventilation techniques all help to improve visual accessibility. Enhancing visual accessibility elements, arranging furniture better, and expanding entry and exit pathways are among the recommendations. The libraries may improve their accessibility and inclusivity and create more hospitable and inclusive environments for all patrons by putting these suggestions into practice.
