You need to submit site level drawings if your proposal involves a significant change in ground levels. Your drawings must show both the existing and finished levels.
These drawings should demonstrate how your proposed development will relate to existing site levels and the neighbouring development.
The site level drawings you submit must:
- show a cross section(s) through the proposed building(s) and site
- be drawn to an appropriate metric scale for example, 1:50 or 1:100
- show existing and proposed with levels related to a fixed point nearby which will not be affected by the proposed works
- show the proposals in relation to adjoining land and buildings
If your proposal involves a change in ground levels, your drawings must show both existing and finished levels including details of:
- retaining structures
- how eaves relate to adjacent land and boundaries.
- an explanation of how you will avoid any encroachment on adjacent land
If your proposal doesn’t include changes to site levels and raising finished floor levels are not to be raised, you can state this on the drawings.
You can get help and advice from our Duty Planner on site levels and planning applications.
You can get detailed feedback on your proposal by using our pre-application advice service.
