Challenge

Securing planning consent for a second-storey roof extension rising above the main building to add a large bedroom and ensuite, whilst preserving the character and appearance of the conservation area following a previously dismissed appeal.

Approach

Developing a high-quality, context-sensitive design with strategic setbacks, reduced height, and simplified massing to minimise visual impact whilst demonstrating how the proposal would enhance rather than detract from the surrounding streetscape.

Solution

Successfully overturning the initial planning refusal through a rigorous appeal process, securing planning permission for a sensitively designed roof extension that significantly improves the home's functionality whilst remaining fully respectful of the conservation area's historic character and contributing positively to the local streetscape.
