Rear extension and dormers at 64 Cwmavon Road, Blaenavon
Summary of planning committee decision
Decided by Torfaen Planning Committee on 24 Sept 2025.
What was proposed
The application proposed demolishing the conservatory, building a rear extension and adding two dormer windows for a home office.
“This application seeks planning permission to demolish the existing conservatory and erect a two-storey, part single storey, extension along the rear elevation of the property. It also seeks to provide two dormer windows within the rear roof plane.”
“The single-storey element of the proposed development would span the full width of the property's rear elevation, measuring approximately 4.7 metres wide and projecting 2.8 metres from the original rear wall. The two-storey section would be positioned along the north- western boundary adjacent to No. 65 Cwmavon Road, with dimensions of 2.4 metres in width and 2.8 metres in depth. This part of the extension would feature a lean-to roof reaching a height of 6 metres.”
Officer report
The site
The property is a traditional mid-terrace house in the Blaenavon World Heritage Area, with a rear garden beside a narrow access lane.
“64 Cwmavon Road is a traditional mid-terrace property, featuring a split-level design (two storeys to the front and three to the rear), situated within the Blaenavon World Heritage Area. The dwelling is flanked by neighbouring properties on both sides and is orientated to face northeast onto Cwmavon Road. To the rear, the garden benefits from a south westerly aspect and adjoins a narrow access lane. The rear elevation is rendered and fitted with white uPVC windows.”

Officers’ recommendation
Officers recommended approval with conditions after finding the proposal acceptable in design, residential amenity, parking, highway safety and ecology terms.
“- The impact of the proposed development on the character and appearance of the existing property and the surrounding area; - The impact of the proposed development on the amenities of surrounding residents; - Highway safety and car parking; and - Ecology.”
“While the introduction of two dormer windows would interrupt the otherwise simple roof plane of the terrace, their modest scale and rear-facing position would limit their overall impact on the character of the area.”
