About this application

This is a planning application for demolition at 46 London Road Shenley Radlett Hertfordshire WD7 9DY. Hertsmere has handled 7,138 applications of this type. This one was decided in 59 days, 3 days longer than Hertsmere's typical decision time. The site is in the Shenley Village conservation area, with 1 listed building nearby. There has been 1 other application at this address. In the past year there have been 124 applications across Shenley. We hold 1,025 applications in total for the WD7 postcode area.

Why it was refused

  1. The proposed development, by reason of layout and design, particularly the introduction of a projecting front gable emerging from an end-hipped roof would create an incongruous form that does not sit comfortably with the established traditional built character of the Conservation Area and would represent poor quality design. The proposals would result in 'less than substantial harm' to the conservation area. Insufficient public benefits exist which would outweigh this harm. The proposal therefore does not comply with the NPPF 2024, policies SP1, CS14, CS22 of the Core Strategy 2013, Policies SADM29 and SADM30 of the Site Allocations and Development Management Policies Plan 2016, the Planning and Design Guide Part E, the Planning (Listed Buildings and Conservation Areas) Act 1990 and the Shenley Neighbourhood Plan 2021.
  2. Having regard to impacts upon neighbours, it has been found that the creation of a new dwelling due to its increased scale, siting, depth and massing would result in a substantial breach of the 45 degree line with the neighbouring dwelling at no.46 London Road and would cause undue harm to the residential amenities of the neighbouring dwelling by virtue of outlook and detrimental overbearing impact. The proposal therefore does not comply with the NPPF 2024, Development Plan including Core Strategy policies SP1 Creating Sustainable Development, CS14, CS22, SADM Policies SADM29 and SADM30, The Planning and Design Guide Part E, the Shenley Neighbourhood Plan 2021.
  3. Insufficient arboricultural information has been submitted to assess impacts on trees within the site and surrounding land, contrary to Policy SADM12 of the Site Allocations and Development Management Policies Plan 2016 and Policy CS12 of the Core Strategy 2013 and the Shenley Neighbourhood Plan 2021. The potential tree loss would harm the area's character and biodiversity, and the benefit of a dwelling fails to outweigh this environmental harm.

From the council's decision notice.
