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 engineer. Production defaults — TypeScript strict, row-level security on the database, structured logging, accessibility audits, schema.org structured data, GDPR-compliant cookie handling — are included by default, not added at the end.
