The K6 project, traveling across the UK to document old red telephone boxes

The K6 project is documenting surviving red telephone boxes across Britain with photos, locations, and design details.

It records box type, door style, and crown emblem, while mapping both reported and visited sites online.

The effort helps preserve an iconic piece of British street heritage as public payphones continue to disappear.

The project also traces the design legacy of Giles Gilbert Scott and earlier box types like the K1 and K2.
