Stratum subdivisions are used to create stratum lots for disposal where vertical subdivision alone will not meet the requirements of the proprietor and the new lots are needed to be limited (either as to whole or part) in height and/or depth e.g.
- Railway tunnels
- Underground railway stations and associated shopping complexes
- Leases of part of the airspace above a road for access between buildings
- Subdivision of a building into stratum lots for separate use and/or ownership
Note For deposited plans defining lengthy road, rail tunnels, etc see Road and rail tunnel developments page.
