Why it was refused

  1. The development, by reason of its scale, form and design, would result in disproportionate and visually intrusive additions which harm the historic character of the terrace and the wider Conservation Area. There are no public benefits which would outweigh this harm and the proposal would fail to preserve or enhance the character or appearance of the conservation area. The proposal is therefore contrary to policies 32, 33 and 34 of the Horsham District Planning Framework (2015), and policies HB3 and HB4 of the Horsham Blueprint Business Neighbourhood Plan (2019-2036).
