Addition of a two storey front extension

Appeal Decision Site visit made on 3 February 2026 by L Clark MSc MRTPI Decision by John Morrison BA (Hons) MSc MRTPI an Inspector appointed by the Secretary of State Decision date: 13 February 2026 Appeal Ref: 6002156 4 Dunstan Walk, Thorne, Doncaster DN8 5UP • The appeal is made under section 78 of the Town and Country Planning Act 1990 (as amended) against a refusal to grant planning permission. • The appeal is made by Mrs. Lydia Marshall against the decision of City of Doncaster Council. • The application Ref is 25/01974/FUL. • The development proposed is the addition of a two storey front extension. Decision 1. The appeal is dismissed. Appeal Procedure 2. The site visit was undertaken by a representative of the Inspector whose recommendation is set out below and to which the Inspector has had regard before deciding the appeal. Main Issue 3. The main issue is the effect of the proposal on the character and appearance of the area. Reasons for the Recommendation 4. The appeal site is a semi-detached property situated on a residential cul-de-sac. Properties on Dunstan Walk are generally pairs of semi-detached dwellings, some with single storey lean to porches but of almost symmetrical and largely original appearances creating a pleasant sense of uniformity. The same matching design features, which often includes one first floor gable per unit, can be seen on Dunstan Drive with groups of terraced properties. The consistency of building form in the area contributes positively to its character and appearance. 5. Although the extension would be constructed using matching materials with a similar pitched gable front, its two-storey nature would be an incongruous feature that would introduce a prominent block to the front of the property. Its forward projection would be a dominant addition that would unacceptably disrupt the otherwise consistent design across the street scene and wider estate. Furthermore, the extension would unbalance the symmetry between the properties. 6. The proposal would therefore cause harm to the character and appearance of the area and would be contrary to Policies 41 and 42 of the Doncaster Local Plan 2021 which are concerned with proposals responding positively to their context amongst other things. Appeal Decision 6002156 2 Other Matters 7. Some of the properties may have had alterations carried out but I did not witness any substantial alterations in the immediate area other than single storey small extensions. That being said, and other than porches and the odd conservatory, even small extensions are the exception rather than the norm in this location and I am therefore not led to recommending that the appeal is allowed in their light. A lack of objection from neighbouring occupiers does not absolve me from making an assessment as to the appeal scheme’s impact in regard to the main issue. The absence of any views made or matter which would be acceptable in the scheme would be a lack of harm and thus neutral in any balance of considerations. Conclusion and Recommendation 8. For the reasons given above, the appeal scheme would conflict with the development plan and material considerations do not indicate a decision other than in accordance therewith. I therefore recommend that the appeal should be dismissed. L Clark APPEAL PLANNING OFFICER Inspector’s Decision 9. I have considered all the submitted evidence and my representative’s report and on that basis the appeal is dismissed. John Morrison INSPECTOR
