Why it was refused

  1. By virtue of its excessive dormer width, flat roofed form and poor proportional relationship to the host roof, the proposal fails to achieve subservient additions, vernacular consistent roof forms, and the careful control of dormers and extensions required by the Mildenhall Conservation Area Design Code (Policy MARL12), which seeks to avoid inappropriate, dominant and visually intrusive alterations in this highly sensitive context. The scheme therefore represents poor design that does not respond positively to local character, contrary to MARL12 of the Marlborough Area Neighbourhood Plan, Core Policy 57 (i & iii) of the Wiltshire Core Strategy and the Wiltshire Design Guide (Appendix D), and is inconsistent with NPPF paragraphs 131 and 135, which require context-responsive, high-quality design.
  2. The scale, bulk and form of the proposed dormer would appear incongruous and visually dominant, disrupting the simple, traditional roofscape and proportions that contribute to the significance of the Mildenhall Conservation Area; as such, the development fails to conserve or enhance the area’s character as required by Policy MARL12’s design code for the Conservation Area and Section 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990. In the absence of clear and convincing justification or public benefits, the identified harm is not outweighed, and the proposal conflicts with Core Policy 58, NPPF Chapter 16, and the local conservation-led design guidance.

From the council's decision notice.
