G) The brickwork to the front elevation to be repointed. H) Ramp to the sunken patio removed and proposed new stairs shown. I) Door access point and wall openings under the front entrance stair to be blocked up and rendered. J) Minor internal alterations. K) All ancillary site works to facilitate the development.
Core Planning Reasoning
The development was recommended for a grant of permission as the scale, form, and design of the proposed amendments were deemed acceptable and unlikely to adversely impact residential amenity or the character of the Protected Structure, provided the roof height is reduced to align with previously permitted levels.
Decision Maker's Conclusion
- The proposed increases in the depth and width of the rear extension are considered minor and would not negatively impact the visual or residential amenity of the neighboring properties at Nos. 8 and 10 Palmerston Road.
- The proposed 1.5m increase in roof ridge height (to 5.6m) is considered overbearing and dominant; however, this is mitigated by imposing a condition to align the roof with the previously approved lower height of c. 3.5m.
- The development, subject to compliance with conservation methodology and reduced roof profiles, would not materially affect the character of the Protected Structure or the surrounding residential conservation area.
