Main issues, as the Inspector framed them

  • The effect of the proposal upon the living conditions at 25 Daymer Gardens with particular regard to visual impact

What decided it

The two-storey side extension would breach the 45-degree rule guidance and create an overbearing visual intrusion in close proximity to the neighbour's living spaces and garden, markedly changing the established sense of space and openness in breach of DMP policies DMHB 11 and DMHD 1.
