Why it was refused

  1. The proposed rear dormer roof extension, by virtue of its design, size and overall massing, would form an unduly dominant addition that fails to appear subordinate to the original roof form. The bulk and proportions of the dormer would disrupt the established roof profile and detract from the character and appearance of the host property. As a result, the development would not comply with the design principles set out in Policies Q5, Q8 and Q11 of the Lambeth Local Plan (2021), London planning@lambeth.gov.uk SW2 9QQ
  2. The proposed hip to gable extension, including the removal of the characteristic front roof slope form, would result in the loss of a roof profile that is a defining characteristic of the host property and the wider group of dwellings. The changes would disrupt the established uniformity and fail to respond positively to the original architectural rhythm of the streetscene. The development would therefore cause harm to the character and appearance of the area, contrary to policies Q5 and Q11 of the Lambeth Local Plan (2021).

From the council's decision notice.
