Why it was refused

  1. The proposal, due to its depth, height and its proximity to the boundary with the attached neighbouring property neighbouring properties, would result in a discordant addition to the main dwelling that would result in an overdominant, overbearing and unneighbourly form of development which would be detrimental and harmful to the reisdential amenities of the occupiers of the attached neighbouring property. The proposed extension would therefore not comply with the policies: Policy DP3 of the NPPF, Policy H4 and Policy D5 of the Guildford Borough Local Plan: Development Management Policies 2023, and the Residential Extensions and Alterations SPD 2018.

From the council's decision notice.
