There were eleven businesses at Quarry End. Some included:
- Radleigh Insulation Supplies
- Castle Ironworks
- Fenchurch Catering Equipment
- Lowland Leather Finishers
- Sentry SuperSacks
Quarry end had a main access road with five smaller roads which, at right angles, branched off to metal, brick and concrete buildings. They were near a hill which had been, in the 19th century, used by quarry workers. 
Around the perimeter, was a metal mesh fence and spikes on top of that. There were sturdy iron gates which were closed and padlocked.
