Why it was refused

  1. The proposed two-storey side extension by virtue of its size, bulk and massing together with the close proximity to the highway with no separation distance from the pavement would be harmful to the street scene and to the character and appearance of the surrounding area. It would be contrary to Policies QD6.2 and QD6.4 of the Watford Local Plan 2021-2038, guidance contained in Sections 8.3.1 and 8.6.1 of the Residential Design Guide 2016 of the Watford Residential Design Guide 2016, the policies QD6.1, QD6.2 and QD6.4 of the Watford Local Plan 2021-2038 and Chapter 12 of the National Planning Policy Framework 2024.

From the council's decision notice.
