Why it was refused
- The proposed first floor rear infill extension and associated roof alterations, by reason of their scale, bulk, massing, crown roof form and poor relationship with the existing pitched roof of the dwelling, would result in a visually dominant, discordant and unsympathetic form of development. The proposal would overwhelm and dominate the existing roofscape, creating an awkward and disjointed appearance which would fail to integrate with, or appear subservient to, the architectural form and proportions of the host property. The harm would be further exacerbated by the prominent and visible nature of the works from the street scene and neighbouring properties, where the altered roof form and upper floor massing would appear incongruous and visually intrusive. The development would therefore fail to respect the character and appearance of the existing dwelling or the surrounding area and is contrary to Policy CS20 of the Core Strategy for Chiltern District (Adopted November 2011); Policies GC1, H13, H15 and H18 of the Chiltern Local Plan Adopted 1 September 1997 (including alterations adopted 29 May 2001, Consolidated September 2007 & November 2011); Policy H7 of Chalfont St Peter Neighbourhood Plan 2013-2028; Chiltern District's 'Residential extension and householder development Supplementary Planning Document; Section 12 (Achieving well-designed places) of the National Planning Policy Framework (2024); and the National Design Guide (2021).
From the council's decision notice.
