Building Information Modelling (BIM) is increasingly recognised as a transformative tool in architectural design, particularly for enhancing sustainability and climate responsiveness. However, its adoption in Nigeria, especially in South-West Nigeria, remains underexplored. This study assesses the current level of BIM adoption among architecture and other construction professionals in the region, with a focus on its application in climate-responsive building design. A mixed-methods approach was employed, including a literature review, surveys, and expert interviews, to evaluate awareness, usage patterns, challenges, and potential benefits of BIM in sustainable architecture. Findings reveal that while BIM is gaining recognition, its integration into climate-adaptive design remains limited due to factors such as high implementation costs, lack of technical expertise, and inadequate policy support. The study highlights the need for targeted training programmes, policy interventions, and industry collaboration to enhance BIM adoption for sustainable architecture in South-West Nigeria. The findings contribute to the discourse on digital innovation in climate-responsive design and provide recommendations for increasing BIM utilization in the Nigerian built environment
