Officer report

Why officers supported it

Officers considered that the design would preserve the conservation area and that the development would protect the living conditions of neighbouring occupiers.

“/PP/25/03754:7 mansard in this instance would be acceptable. It should however be noted that any granting of permission in this case would not set a precedent for other properties along this terrace, as each application would need to be assessed on its own merits taking into account the relevant material considerations for each case and site.”

“The rear windows and terrace would not create any significant new angles of views which would result in overlooking/loss of privacy, sense of enclosure, light pollution and nor loss of sunlight/daylight. 6.30Given all of the above, the proposals would ensure good living conditions for occupants of new, existing and neighbouring buildings, in accordance with policies CD9, GB7 and GB10 of the Local Plan.”

Officer report

Residents’ concerns

Objections concerned the mansard, privacy, the number and effect of applications, and whether previous residents’ concerns had been addressed.

“/PP/25/03754:9 granted only after the removal of the proposed mansard from the plans. assessed against the relevant policies and other material considerations and found that on balance, it is acceptable. A detailed assessment of this is within paragraphs 6.14 - 6.21. 2 Through series of applications and approvals by the council the property bears no resemblance to what was original nor what was approved in December 2024.”

“Certain conditions have been recommended so that the living conditions of neighbouring properties are preserved. 4 Objection to the mansard as it will be visible from private views from the rear of Chepstow Villas, including private terraces being overlooked from the mansard windows; loss of privacy. There is already mutual overlooking between properties, in particular from within the properties (private views).”
