The development will consist of addition of new second floor rear extension above existing two-storey rear return; alteration of existing rear roof of main house and addition of new setback roof extension to provide ceiling height for habitable room; addition of raised planting area to rear roof for privacy; and all ancillary works necessary to facilitate the development.
Core Planning Reasoning
The Inspector recommended the retention of Condition 2 (effectively scaling back the development) because the proposed extensions were excessive in scale, not visually subordinate to the host dwelling's roof, and would negatively impact the character of the Architectural Conservation Area (ACA).

- Retention of Condition 2 is necessary to ensure the development complies with the guiding principles for extensions in residential conservation areas and protects the visual and residential amenities of the area.
