Why it was refused

  1. The applicant has failed to demonstrate the impact of the extension on neighbouring properties and existing occupiers with regard to loss of light. The Daylight and Sunlight Report, prepared by CHP Surveyors, dated 6th February 2025, does not identify all relevant residential development surrounding the site (including Seclow House and the remainder of Eton Mews) and therefore, a full assessment of the impacts of the development could not be made as required by sAA.2(g) of The Town and Country Planning (General Permitted Development) (England) Order 2015, Policy D5 of Plan:MK, and Policy CMKAP G10 of the Central Milton Keynes Business Alliance Plan.
  2. An appropriate assessment of adequate waste facilities has not been provided and the waste facilities shown do not meet the expected standards set in the Residential Waste collection planning guidance (2024). As such, the application fails to establish that the amenity of the existing occupiers or surrounding users would not be impacted by inadequate provision of refuse storage areas as required

From the council's decision notice.
