Sections and levels

Guidance on how to correctly produce section and levels plans of a site to accompany a planning application.

Existing and proposed site sections and finished floor and site levels, where a change is proposed. These should show:

  • How the proposed development relates to existing site levels and adjacent development (with levels related to a fixed datum point off site)
  • Details of existing and proposed foundations and eaves where a change is proposed
  • How encroachment onto adjoining land is to be avoided.
