Main issues, as the Inspector framed them

the visual effect of the proposal on the external appearance of the building
the transport and highways impact of the proposed development

What decided it

The external appearance of the proposed extension, with its contrasting vertical design, zinc cladding, and dark grey windows, would be visually incongruous and harmful to the existing building, failing to satisfy the prior approval criteria despite acceptable highway impacts.

Framework references: 111

Plan policies cited: CS8, DM10, DM8, DM9
