Enhancing Public Engagement in Architectural Design: A Comparative Analysis of Advanced Virtual Reality Approaches in Building Information Modeling and Gamification Techniques

Purpose: This paper investigates the potential of virtual reality (VR) technologies—specifically, building information modeling (BIM) (“Autodesk Revit”) and game engines (“Unreal Engine”)—to enhance public involvement in the design and execution of architecture and urban projects. The main research question focuses on comparing the effectiveness of these two methods in creating an interactive design model for participatory design in public spaces. Methods: The study employed a VR exploratory experiment with 33 participants, followed by semi-structured interviews to analyze two recent developments in London: the Sky Garden, and Crossrail Place Roof Garden. Participants interacted with the design models and provided feedback on their experiences. Results: The findings demonstrate that integrating VR with BIM software using the Enscape plugin effectively enhances user involvement, enabling real-time generation and testing of design alternatives. While both methods were found to be beneficial, participants reported a preference for the direct implementation of VR in BIM software. Conclusions: This research highlights the potential of VR technologies—specifically, BIM and game engines—as a co-design approach for public and social spaces in urban environments. It also identifies limitations and future research opportunities in adopting these methods for participatory design.
