Approved

As officers recommended.

  • Officers advised approval because the proposal would provide housing while preserving the listed building and avoiding unacceptable effects on neighbours.
  • Seven objections raised concerns about heritage, residential amenity, parking, crime, noise, waste and the quality of accommodation.
  • The committee agreed to grant permission, subject to conditions, including management and crime-prevention measures.

Radon affected area, class 5
An estimated 10 to 30% of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.
From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.

Checked on 16 October 2026.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
