New advances in user studies within Immersive Virtual Environments (IVEs) have made possible highly immersive Pre-Occupancy Evaluations (Pr-OEs) during the architectural design process. However, there remains a lack of easy methods for integrating these IVEbased user studies into design development phases while also providing reliable datadriven results. In VREVAL, a framework for IVE-based architectural user studies, several technical and interface solutions for architectural user studies have been addressed. In the following paper, recent developments in the VREVAL hybrid web platform and desktop application will be reviewed via the presentation of a partial Pr-OE of four alternative train station designs. By examining the design process of a route choice user study which compares four schematic designs, the VREVAL modular methods for creating study tasks and questionnaires within a BIM-generated IVE will be demonstrated.
