Archaeological Priority Areas.
Areas where there is a defined likelihood of buried archaeology. They do not stop development, but they put an evaluation and often a watching brief between you and a start on site.
- Development with shallow foundations
- Building over previously disturbed ground
- Schemes preserving remains in situ
- Piling designs that minimise ground disturbance
- Basements and deep excavation
- New foundations on undisturbed land
- Any scheme where evaluation is left to condition stage
Where a site has archaeological potential, the applicant must describe the significance of any heritage asset affected, including a desk-based assessment and, where necessary, a field evaluation — before the application is determined, not after.
Most schemes proceed with conditions: evaluation, then a written scheme of investigation, then recording during groundworks. Refusal is reserved for cases where remains of national importance would be lost.
The programme risk is real and manageable: an early evaluation lets you design the foundations around what is found, whereas discovery mid-groundworks stops the site. Budget for it at feasibility rather than treating it as a condition to be discharged later.
How schemes actually fare inside this designation — approval rates, appeal survival, which authorities apply it hardest — needs the designation joined to the decision record. That join isn’t built, so those figures aren’t published here. We won’t estimate them.
Check whether a site falls in a priority area before fixing a basement — evaluation is far cheaper than a redesign after discovery.
