About this application

This is a planning application at 5 Dunston Hill Tring Hertfordshire HP23 4AX. Dacorum has handled 6,920 applications of this type. This one was decided in 13 days, 5 weeks quicker than Dacorum's typical decision time. There has been 1 other application at this address. We hold 814 applications in total for the HP23 postcode area.

Why it was refused

  1. It is considered that the installation of a first floor side facing window into the approved two-storey side extension has the potential to impact upon the adjoining neighbours' privacy amenity. Therefore, a full assessment and neighbour consultation is required and the amendment cannot be concluded as non-material. As such, the proposed is considered to be material and the application is therefore contrary to Section 96A of the Town and Country Planning Act 1990.

From the council's decision notice.
