The project pairs a physical scale model of the Lahdenväylä area, roughly three by four metres, with digital layers seen through Meta Quest 3 headsets. Visitors explore development scenarios through 3D building models, transport networks, zoning, flood risk and noise data, placed directly on the model.
It was developed at Helsinki XR Center within the Immersive Sustainability Lab, launched in autumn 2024.
The model shown in the site’s third chapter is a spatial study, not project documentation.
