The development will consist of the reconstruction of the existing rear dormer roof structure at the top floor with a wider dormer structure, which is a change to that permitted under reg.ref. WEB1432/21.

Core Planning Reasoning

The Inspector recommended that Condition No. 3 (reducing the dormer width) be deleted, concluding that the proposed 4.2-metre width is acceptable as it is not visible from the public realm, provides improved internal accommodation, and maintains a reasonable scale relative to the roof slope without injuring residential amenities.

Decision Maker's Conclusion

  • The proposed dormer width of 4.2 metres is considered visually subordinate to the roof slope and remains below the ridge and above the eaves, maintaining sufficient separation from the roof edges.
  • As the rear roof slope is not visible from the public realm, the modification does not negatively impact the streetscape or the architectural character of the area.
  • There is established local precedent for similar larger dormer structures, and the proposal is consistent with the proper planning and sustainable development of the Z1 zoned area.
