Why it was refused

The front boundary works to include the dropped kerb and vehicular hardstanding with associated vehicular access gate, by reason of the harmful urbanising effect, would amount to less than substantial harm to the special historic and architectural interest of the Grade II Listed Building and the rural character of the Patchetts Green and Delrow Conservation area. The proposed development would have an adverse effect on the rural setting of the listed building. Insufficient information and justification have been provided to adequately assess the level of harm and no public benefits are considered to arise. Therefore, it is concluded that there are insufficient public benefits as per paragraph 214 of the NPPF, to justify the harm that would arise. Therefore, the development conflicts with the Planning (Listed Buildings and Conservation Areas) Act 1990 (as amended), the NPPF 2024, Policy SADM29 of the Site Allocations and Development Management Polices Plan (2016), and Policy CS14, of Hertsmere's Core Strategy (2013).

From the council's decision notice.
