Why it was refused

The proposed works involve extensive works which will impact the fabric of the roof, in a location which has been identified as being suitable for foraging bats due to the number of trees within the vicinity and the surrounding verdant character. The applicant has failed to submit a preliminary ecological survey or any bat survey. Without adequate survey information it is not possible to assess the impacts of the development on any potential protected species and thus meet the requirements of the National Planning Policy Framework. This information needs to be assessed as part of a planning application, otherwise it is not possible to ascertain what mitigation may be required or whether the proposal would have an unacceptable impact on protected species. As such, there is insufficient information to demonstrate that the proposal would conserve and enhance biodiversity and the proposal is therefore contrary to: Policy CS24 of the Core Strategy for Chiltern District (Adopted November 2011); Policy NC1 of the Chiltern Local Plan Adopted 1 September 1997 (including alterations adopted 29 May 2001, Consolidated September 2007 & November 2011); the NPPF (2026); The Conservation of Habitats and Species Regulations 2017 (as amended); and Sections 40 and 41 of the Natural Environment and Rural Communities Act 2006.

From the council's decision notice.
