Decided by Portsmouth Planning Committee on 9 Sept 2026.
Approved
As officers recommended.
- Officers advised conditional permission because the terrace would preserve the conservation area and cause no harm to heritage assets.
- Twelve representations objected, citing the glass balustrade, visibility, overlooking, noise, height and effects on the conservation area.
- The committee granted conditional permission, amending the swift-box condition to require consultation on placement.
