Main issues, as the Inspector framed them

  • The effect of the proposal on the living conditions of the occupiers of 1 Tysons Garden, with particular regard to outlook

What decided it

The substantial vertical bulk of the rear extension along the boundary, which significantly reduces outlook from the neighbouring property's garden and rear kitchen window, creating a confined and oppressive effect that conflicts with Policy QD9.
