Why it was refused

  1. The overall design and form of the proposed development would have a negative impact on the setting of the Grade II Listed Building (Walkern United Free Church), causing less than substantial harm to its significance. In addition, the overall design, form, and location of the dwellings would appear out of character in the Walkern Conservation Area and would have a detrimental effect on the rural setting of the village. The proposal would therefore fall contrary to District Plan Policies GBR2, VILL1, DES4, HA1, HA4, HA7, Policies WLK3 and WLK14 of the Walkern Neighbourhood Plan, Section 16 of the National Planning Policy Framework, and Section 72 of the Planning (Listed Buildings and Conservation Areas) Act 1990.
  2. There is insufficient information to demonstrate the proposed dwellings would qualify as self-builds. Therefore, the proposed development would not be eligible for the self-build exemption regarding the mandatory biodiversity net gain (BNG) requirements. As no existing/proposed habitat plan or biodiversity metric has been submitted with the application, the Local Planning Authority are unable to ensure the proposed development would achieve the mandatory 10% net gain. The development therefore fails to comply with the mandatory 10% BNG required under Schedule 7A of the Town and Country Planning Act 1990 (as inserted by Schedule 14 of the Environment Act 2021).
