What consultees said
Historic England identified low-level conservation area harm, while highways, waste and plant consultees raised no objection subject to conditions.
“HISTORIC ENGLAND: Historic England identified less than substantial harm to the Bayswater Conservation Area and stated that ‘Historic England recommends that your authority should only grant planning permission if persuaded that the harm has been minimised and would be outweighed by public benefits.”
“Following a reduction in height at the St Matthews’ Church elevation, to address the request from Historic England that harm the the Conservation Area is minimised, Historic England provided an addendum to the original comments stating they welcomed the reduction of point a) and acknowledges that harm has been minimised in line with paragraph 208 of the National Planning Policy Framework (NPPF).”

Objections from residents
Residents and local groups objected to design, heritage, overlooking, light pollution, noise, daylight, traffic, parking and increased commercial activity.
“Amenity - The proposed "walls of glass" would cause problems of overlooking and light pollution, both on Chapel Side and St Petersburgh Place. The proposed terraces would cause problems of overlooking and noise pollution, both on Chapel Side and St Petersburgh Place…”
“- Objection on the grounds of the use of the mirror massing assessment in the daylight/sunlight assessment - Objection on the grounds that both the roof extension and the infill are excessive in height and would result in a sense of enclosure for neighbouring residents - Objection on the grounds of overshadowing for terraces and courtyards of properties on Chapel Side - Objection on the grounds of noise reflecting off the glass and building will have an impact on neighbours…”
