Main issues, as the Inspector framed them

  • The effect of the retention of clear glazing within the first-floor gable end windows on the dark night skies and ecological interests of the South Downs National Park, with particular regard to light spill and its effects on bats

What decided it

The existence of a realistic fallback position whereby comparable windows could lawfully be installed with obscure glazing, combined with the additional mitigation measures (tinted glazing and blackout blinds) incorporated in the appeal proposal, meant that no material harm to dark night skies or ecological interests would arise.

The benefits of retaining clear glazing with enhanced mitigation measures (tinted glazing and blackout blinds) outweighed any potential harm to dark night skies and ecological interests when assessed against the realistic fallback position of obscure-glazed windows.
