Third front dormer at Cartrefle Station Hill, Aberfan, Merthyr Tydfil

What was proposed

The application sought to add a third front dormer by varying the approved plans for the property.

“This application seeks planning permission to vary condition 2 (list of approved plans and documents) of planning permission P/25/0316 to include an additional dormer to the front roof elevation.”

“The previously approved householder application (P/25/0316) featured numerous works, which included the addition of two new dormers to the front roof profile, a new garage and storage shed. Permission is sought to amend the approved drawings relating to the plans and elevations of the property to include an additional dormer to the front roof profile, resulting in a total of 3 small dormers being introduced to the front roof profile.”

Officer report

The site

The site is a large detached dwelling on an elevated, spacious plot in a residential area with varied nearby homes.

“The application site relates to a large detached dwelling (Cartrefle), located off Station Hill in the residential area of Aberfan. The dwelling, which is elevated above the front highway (Station Hill), is accessed via an array of steps, since Station Hill slopes down significantly from the south to the north.”

“The property sits within a relatively spacious plot and is perceived as being somewhat segregated from other nearby properties, given its stonework and rendered wall enclosure around its perimeter. The surrounding area comprises a variety of properties, from terraced and semi-detached properties, as well as detached dwellings, all of which are modest in scale and design and traditional in appearance.”

Officer report

Earlier permission

Earlier permission approved two front dormers, a garage and a store, and this application sought to amend those approved plans.

“The following planning history is relevant to the consideration of the application:”

“P/25/0316 – Proposed front dormer windows, demolition of storage sheds and new garage and store – Approved: 12 th March 2026.”

Officer report

Officers’ assessment

Officers considered the dormer sympathetic and proportionate, with no significant additional harm to the street scene or neighbouring privacy.

“The proposed dormer, in respect of its scale and finishes, would be identical to the other two dormers which already benefit from planning permission. Furthermore, the introduction of this additional dormer, would not result in the re-positioning of the approved dormers. Instead, the proposed dormer would sit centrally between the two approved dormers and, like the approved dormers, would align with the dwelling’s existing fenestration arrangement.”

“It is recognised that an additional dormer could have additional impacts upon neighbouring residents, in particular, No. Ael y Bryn, which lies to the north of the application site. However, the proposed dormer, like the approved dormers, would be front facing, and any additional overlooking opportunities would be towards Station…”
