Core Planning Reasoning
The proposed extension is considered to be in accordance with the Z1 zoning objective as it is a modest, subordinate development that respects the site's historic configuration and does not significantly injure the residential amenities of the neighboring property through overbearing, overlooking, or material loss of daylight.

- Privacy is maintained through the strategic positioning of rooflights and the absence of windows on the gable end, ensuring no new overlooking issues are created.
