118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision Site visit made on 6 August 2025 by J Moore BA (Hons) BPl MRTPI an Inspector appointed by the Secretary of State Decision date: 22 August 2025 Appeal Ref: APP/N5090/W/25/3367137 118a High Road, East Finchley, Barnet, London N2 9ED • 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 Kocakerim against the decision of the Council of the London Borough of Barnet. • The application Ref is 25/1546/FUL. • The development was originally proposed as mansard roof extension to create an additional 1x1- bed self-contained flat. Decision 1. The appeal is allowed, and planning permission is granted for mansard roof extension with front, side and rear dormer windows to create a 1no. self- contained flat at 118a High Road, East Finchley, Barnet, London N2 9ED in accordance with the terms of the application, Ref 25/1546/FUL, subject to the conditions in the attached schedule. Preliminary Matters 2. My banner heading above details the description of development as originally proposed on the planning application form, but this includes words that are not acts of development.

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision The description used on the decision notice is ‘Mansard roof extension with front, side and rear dormer windows to create a 1no. self- contained flat. Associated cycle and refuse/refuse storage.’ It is clear from the plans and accompanying details that the proposal does not indicate details for cycle and refuse storage. However, the first part of that description is a more precise one than that originally proposed, and I have therefore used this part as the description of development in my formal decision above. 3. The appellant submitted an amended plans to the appeal, to indicate an altered floor to ceiling height to the proposed flat. Having regard to relevant case law1, the amended scheme would not result in a substantial or fundamental change to result in a different application. The Council and any interested parties have had an opportunity to comment on the amended scheme. I therefore consider that no party would be unfairly prejudiced by my acceptance of the amended scheme. Background and Main Issues 4. The appeal building is of three-storey height, to include retail/commercial use at the ground floor, with self-contained flats above.

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision Appeal Decision APP/N5090/W/25/3367137 an upward extension to provide a further flat. The amended appeal scheme seeks to overcome the sole reason for refusal which concerns the internal height of the proposed flat. However, the Council considers that if the amended scheme were to increase the overall height of the proposal, this would have a harmful impact on the character of the area. Therefore, having regard to all the evidence before me, the main issues are: • whether the proposal would provide suitable living conditions for future occupiers, with particular regard to internal floor to ceiling height; and • the effect of the proposal upon the character and appearance of the area. Reasons Living conditions 5. Taken together, Policy D6 of The London Plan 2021 (LP) and Policy CDH01 of the Barnet Local Plan 2025 (BLP) seek to ensure development is of a high- quality design, in accordance with defined standards. For private internal space, the minimum floor to ceiling height must be 2.5m for at least 75% of the gross internal area to achieve adequate daylight penetration, ventilation, cooling and a sense of spaciousness.

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision As originally submitted, the proposed floor to ceiling height was indicated to be 2.4m, and thus it would fall short of the standard. The amended appeal scheme demonstrates the standard would be met. 6. There is no suggestion on the Council’s part that the amended plans misrepresent the external and/or internal height of the building as existing or as proposed. It seems to me that the amended plans indicate that the overall height of the building would be the same as that originally submitted, and the required ceiling height is achieved within the envelope of the mansard roof as originally submitted. I am therefore satisfied that the proposal would meet the required standard. 7. For the reasons above, I conclude that the proposal would provide suitable living conditions for future occupiers, with particular regard to internal floor to ceiling height. The proposal accords with LP Policy D6 and BLP Policy CDH01, whose objectives I have set out above. Character and appearance 8. The appeal building is located at a corner along High Street within East Finchley town centre. As the Council accepts, there are similar mansard roof extensions present at other corner locations within the area.

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision I also saw a variety of roof forms in the area, some elaborately decorated to include clay gables and pediments. The proposed mansard roof, including its proposed dormer windows would not be out of keeping within this roofscape. The use of matching materials as indicated on the proposed plans, and the use of lead cladding to the proposed dormer windows would result in a harmonious appearance to its host building and within the street scene. 9. As originally submitted, the Council found that the proposed roof extension would not significantly increase the height of the building. In the previous main issue, I have found that the amended scheme would be within the envelope of that as originally proposed. On this basis, the scheme would not be any higher https://www.gov.uk/planning-inspectorate 2

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision Appeal Decision APP/N5090/W/25/3367137 than originally submitted. Even if the proposal were slightly taller (by about 0.1m), this would not be so significant that it would not dominate the street scene, nor unacceptably harm the character or appearance of the building and the surrounding area. 10. For the reasons above, I conclude that the proposal would not unacceptably harm the character and appearance of the area. It accords with LP Policies D3 and D5; and BLP Policies CDH01, CDH05 and TOW01. Taken together, these policies support development proposals for incremental intensification, including by upward extensions, and in town centres where mixed uses are supported, providing they respect local context and the character and appearance of the area. Other Matters 11. The proposed kitchen would be above an existing bedroom. Consequently, this arrangement could result in noise and disturbance to neighbouring occupiers. However, the Council accepts that this matter can be controlled by a suitable condition, and I find no reason to consider otherwise. Conditions 12.

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision I have considered the conditions suggested by the Council, comments from the appellant including pre-commencement, and in light of Planning Practice Guidance (PPG). For clarity, precision and to ensure compliance with the PPG, I have undertaken some amendments, editing and rationalisation. The appellant has indicated their written agreement to the terms of those conditions requiring compliance prior to the commencement of development, as per section 100ZA of the Act. 13. I have imposed conditions to secure a time limit for commencement and to require the development to be completed in accordance with the approved plans. These conditions are necessary in the interests of clarity, precision and enforceability. A condition to control the materials for the external surfaces of the development is necessary in the interests of the character and appearance of the area. 14. A Demolition and Construction Management and Logistics Plan is reasonable and necessary to ensure public safety and the operation of the highway network; and to protect the reasonable amenity of neighbours during demolition and/or construction works.

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision This is imposed as a pre-commencement condition to ensure that suitable controls and measures are in place prior to any demolition and construction works taking place. A further condition to control the hours of demolition and construction works is necessary in the interests of neighbouring occupiers. 15. In the interests of climate change, conditions are imposed to ensure the efficient use of water and carbon reduction. A condition to ensure suitable arrangements for cycle parking and cycling storage is reasonable and necessary in the interests of sustainable transport. I have imposed a condition to ensure suitable arrangements are in place for the storage and collection of waste and recycling in the interests of the character and appearance of the area, and the amenities of both neighbouring and future occupiers. A condition to secure compliance with sound insulation measures as per the Building https://www.gov.uk/planning-inspectorate 3

118a High Road, Barnet, London, N2 9ED — London Borough of Barnet — Appeal Decision Appeal Decision APP/N5090/W/25/3367137 Regulations is reasonable and necessary in the interests of the amenity of neighbouring occupiers and sustainable construction. Conclusion 16. For the reasons given above, I conclude that the proposal accords with the development plan, read as a whole. The appeal should therefore be allowed, and planning permission should be granted, subject to the conditions I have set out.
