Why it was refused

  1. The proposal by nature of its height, depth and width and flat roof design would result in a visually prominent addition to the dwelling which would be detrimental and harmful to the visual amenities of the street scene and would fail to comply with Policies H4 and D4 of the Guildford Local Plan Development Management Policies March 2023 and the Residential Extensions and Alterations SPD 2018 and the National Planning Policy Framework.
  2. The extension by reason of its height, width and proximity to the northern boundary with No. 23 Colburn Crescent would result in an overbearing, overdominant and unneighbourly form of development which would be detrimental and harmful to the residential amenities of the occupiers of the attached neighbouring property No. 23 Colburn Crescent and would fail to comply with Policies H4 and D4 of the Guildford Borough Local Plan Development Management Policies March 2023, the Residential Extensions and Alterations SPD 2018 and the National Planning Policy Framework.

From the council's decision notice.
