Why it was refused
- The proposed works by virtue of their cumulative impact would result in less than substantial harm to the significance and setting of the Grade II listed building, which is assessed to be at a high level. The submitted drawings and supporting information fail to demonstrate that this harm is necessary, proportionate, or sufficiently justified, and do not clearly establish that the public benefits of the proposal would outweigh the harm identified. Brentwood Borough Council, Town Hall, Ingrave Road, Brentwood, Essex CM15 8AY The proposals would therefore fail to preserve the listed building, its setting, or its special architectural and historic interest, contrary to the statutory duty under section 16(2) of the Planning (Listed Buildings and Conservation Areas) Act 1990, Policies BE14 and BE16 of the Brentwood Local Plan and Chapter 16 of the National Planning Policy Framework.
- In the absence of a Preliminary Ecological Appraisal, the Local Planning Authority cannot be satisfied that the development would not result in harm to protected species or their habitats, or that appropriate avoidance, mitigation, or compensation measures could be identified and secured. Consequently, the proposed development fails to demonstrate the proposal would conserve and enhance biodiversity or wildlife interests. The proposed development is contrary to policy NE01 of the Brentwood Local Plan, in addition to the aims of the National Planning Policy Framework which requires development proposals to be informed by proportionate ecological evidence where there is a reasonable likelihood of ecological constraints.
From the council's decision notice.
