Intuitive visualisation tools are essential for the effective coordination of construction projects to convey complex spatial and technical information to diverse stakeholders. Traditional design documentation using 2D drawings and static 3D models cannot accurately depict complex spatial relationships and construction sequences. This results in design misinterpretations, inefficient constructability reviews and rework costs. Most of the current extended reality (XR) deployments in construction are essentially used as visualisation tools. Gamification usage in the industry is mainly oriented to the educational workflow context. This study develops an Extended Reality Information Space (XRIS), a HoloLens-based system that spatially anchors construction data onto physical environments. The system operates through gaze-triggered information tags and embedded game-based mechanics. Three functional layers covering immersive visualisation, information management, and interaction and gamification were comprised in this system. Semi-structured interviews were conducted with eight construction professionals and two XR specialists to identify the benefits of XRIS implementation and the impact of gamification on XRIS. Data were then analysed using thematic analysis. The findings suggest that XRIS enhanced spatial understanding, user accessibility, team communication, and motivation. Gamification integrated in the visualisation layer maintained the users’ engagement through the behaviour of spatial exploration and task completion. Both mechanisms supported deeper retention and more precise articulation of design logic than passive documentation review. This study contributes a professional-oriented, empirically evaluated XRIS configuration advancing immersive tool design for construction practice.
