A major challenge in developing 3D cadastral databases is integrating legal spaces and physical elements within a 3D environment while aligning with international standards and connecting to external databases. This paper presents a database implementation based on LADM Edition II, integrated with the IFC standard to support both legal and physical aspects. The model links to authoritative spatial data sources in the Victorian cadastral system. The process covers conceptual, logical, and physical data models, addressing challenges during transformation and proposing solutions. It also outlines complexities in normalisation, data preparation, and the ETL process, including creating 3D legal spaces, extracting boundary faces, representing vertical extents such as airspace rights, and applying virtual boundaries. The database is evaluated through 3D spatial queries and visualisations using a real-world case study from Victoria, Australia. Findings demonstrate that the Victorian cadastral system complies with LADM Parts 1, 2, and 5, and provides guidance for implementing Part 6.
