Summary
A first-floor rear extension refused for exceeding SPD depth guidance by about 0.5 m was allowed. The inspector held that the SPD is guidance to be applied with judgement, and there was no harm to the neighbours (DL ¶14).
What made the difference
The council's mechanical use of SPD formulae. The Framework played no part.
