Main issues, as the Inspector framed them

  • The effect of the proposed side extension on the character and appearance of the area around Ash Close

What decided it

The end-terraced location of the property with significant space to neighbouring properties beyond the site boundary means the extension would not be a prominent feature in the streetscene and would not conflict with Policy 28 or the SPD guidance on residential extensions.

What the Inspector cited

Development plan policies
Policy 28 of the Sutton Local Plan 2016-2031Design of Residential Extensions SPD

How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
