Why it was refused
- The design, scale and footprint of the proposed extension and garage fail to complement the scale and character of the host dwelling or the surrounding locality. Owing to its prominent position, substantial footprint, overall scale and massing, and the inclusion of rooflights serving an upper floor, the proposed garage would appear unduly conspicuous and visually intrusive. In combination, the proposed extension and garage would result in a disparate grouping of buildings that would erode the open valley character of the Mears Ashby Conservation Area. Consequently, the development would fail to preserve or 25/01186/HFUL enhance the character and appearance of the Mears Ashby Conservation Area, contrary to Section 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990, Policies 2(a), (b), and (d) and 8(d)(i) and (ii) of the North Northamptonshire Joint Core Strategy, and paragraphs 212, 213, 215 and 219 of the National Planning Policy Framework.
- The proposed roofing materials and cladding would be uncharacteristic of the palette of materials identified in the Mears Ashby Village Design Statement. The materials neither match nor complement the main body of the existing building and would be contrary to the Mears Ashby Village Design Statement Materials Guidelines 1 and 2, resulting in a design that is not in keeping with the character and appearance of the locality. The proposal is contrary to Policy 8 (d) (i) and (ii) of the North Northamptonshire Joint Core Strategy and Materials Guidelines
