Case study: Rear extension in High Wycombe
In 2024, a homeowner in High Wycombe proposed a rear single-storey kitchen extension. Although the depth met typical Permitted Development thresholds, the property lay within an Article 4 Direction area close to a conservation zone. This meant a full planning application was required. The scheme was approved in just over 8 weeks, subject to conditions for matching brickwork, roof pitch and window design. Careful drawings and a design note addressing High Wycombe’s conservation character helped avoid refusal.
