About this application

This is a planning application for demolition at 12 Cashio Lane Letchworth Garden City Hertfordshire SG6 1AX. North Hertfordshire has handled 6,871 applications of this type. This one was decided in 54 days, 5 days longer than North Hertfordshire's typical decision time. The site is in 1 listed building nearby. There have been 2 other applications at this address. In the past year there have been 102 applications across Letchworth Norton Ward. We hold 910 applications in total for the SG6 postcode area.

Why it was refused

  1. By virtue of the proposal's scale and design, it is considered that the proposal would cause unacceptable harm to the listed building with no identified public benefits to outweigh said harm. The impacts of the proposal on the character and appearance of the building and its significance as a designated heritage asset are therefore not considered acceptable. The proposal fails to comply with Policies D1 and HE1 of the North Hertfordshire Local Plan 2011-2031, and HE5 and HE6 of Section 20, of the National Planning Policy Framework 2026.

From the council's decision notice.
