What we built
A 3D digital-twin viewer built from OpenStreetMap building data: real extruded buildings across London, Manchester, Leeds and Birmingham, height-coloured for instant scale reading, with tilt, sun-direction and auto-orbit controls. Built with MapLibre GL on keyless open data, the kind of planning-team tool that usually lives behind a login, here as an open, working demo.
Highlights
- Real extruded OpenStreetMap buildings across four UK cities
- Height-coloured massing with tilt, sun-direction and orbit controls
- MapLibre GL on keyless open data, live in the browser

How it was built
Like every project at BozApps, this was designed, built, deployed and (where the engagement included it) operated end to end by the same person. Production defaults such as TypeScript strict, row-level security on the database, structured logging, accessibility audits, schema.org structured data and GDPR-compliant cookie handling are included from the start, not added at the end.
