Planning conditions
  1. Existing and proposed roof plan to scale in metric and with scale bar added.
  2. You are required to complete the Community Infrastructure Levy form (CIL) Please find the link below to the form and additional information guidance. http://www.planningportal.gov.uk/uploads/1app/forms/cil_questions.pdf http://www.planningportal.gov.uk/uploads/1app/cil_guidance.pdf
  3. This proposal CONSTITUTES DEVELOPMENT within the meaning of Section 55 of the Town and Country Planning Act 1990, and a planning application IS REQUIRED. This is because the construction of the: • single storey rear/side extension does not comply with the requirements of Class A, namely A.1(f), as it would extend beyond the rear wall of the original dwellinghouse by approx. 4.29 metres, where the threshold is 3 meters; and • rear dormer roof extension does not comply with the requirements of Class B, namely B.2(b)(i), as, as part of this development, it would not be maintained or reinstated the eaves of the original roof, and the rear dormer would not be setback 0.2 metres from the eaves of the dwelling. As such, the proposal fails to meet criteria laid down in the Town and Country Planning (General Permitted Development) (England) Order 2015 and any subsequent legislative amendments.
  4. For the avoidance of doubt the Drawing(s) No(s) and Document(s) to which this decision refers are as follows:- Proposed Floor Plans and Elevations ref.: P2 - received 7 August 2026. Location Plan Existing floor Plans & Elevations ref.: P2 - both received 30 July 2026.
