House extensions and garage at 98 Bryn Ifor, Mountain Ash
Summary of planning committee decision
Decided by Rhondda Planning and Development Committee on 14 Aug 2025.
What was proposed
The application proposed house extensions, an attic dormer, demolition of the existing garage and a new detached garage with retaining walls.
“The application also includes the construction of a detached garage within the rear garden, which is proposed to be sited along the rear boundary of the property and measure 7.1 metres in width by 4 metres in depth, to be enclosed by a flat roof to a height of 3 metres.”
Officer report
The site
The property is a two-storey semi-detached home in a residential area, on a rectangular plot with neighbouring gardens and a rear access highway.
“The application site is located within a residential area of Mountain Ash and consists of a two-storey, semi-detached property which is set within a rectangular shaped plot. The property faces a south-westerly direction with the principal elevation set back from and below the level of the adopted highway (Bryn Ifor) by a small enclosed front garden.”
“APPLICATION NUMBER – 25/0668/FUL REPORT Neighbouring properties in the immediate area are of a similar scale and design to the application property. It is noted that very few properties within the wider street scene have been extended, with none of the immediate neighbouring properties having extensions.”
Officer report
Earlier application
This was a resubmission of an application refused in June 2025, with changes to the rear extension, dormer and garage.
“This application constitutes a re-submission of a previously refused application at the site (25/0521/FUL). The re-submission differs in that the two-storey rear extension has been slightly reduced in depth, the rear dormer extension has been pulled back from the roof the of the two storey extension and now sits fully within the rear plane of the roof, and the proposed garage has been significantly reduced in depth and the rooftop garden removed from the proposal.”
“25/0521/FUL: Single storey extension to side, two storey rear extension, rear dormer extension, and new detached garage with roof garden. Decision: 06/06/2025, Refused.”
Officer report
Why approval was advised
The extensions and garage were considered acceptable in visual terms and unlikely to cause significant harm to neighbours’ amenity or privacy.
“Objectors have raised concerns that the scale of the proposed development is unacceptable for its setting, constituting overdevelopment, and note that none of the immediate neighbouring properties benefit from extensions. Consideration has been given to the objector’s concerns; however, the extensions as proposed are considered to be acceptable in terms of their scale, design and overall visual appearance for the following reasons.”
“The proposed works are subsequently considered to be acceptable in terms of the impact they would have on the residential amenity and privacy of neighbouring properties, complying with Policy AW5 of the Rhondda Cynon Taf Local Development Plan.”
Officer report
Objections raised
Four objections concerned construction access, privacy, light, street character, overdevelopment, boundary position, a missing tree and work already begun.
“The application has been advertised by means of direct neighbour notification. Four letters of objection have been received and are summarised as follows:”
“Concern is raised that the rear access will be blocked during construction. • The extension will result in loss of privacy and overlooking of neighbouring gardens. • Concern is raised regarding loss of light. • There is not even a single storey extension on this side of the street and the proposal would impact the character of the street. • The proposal will result in overdevelopment of the site.”
Officer report
Committee decision
The committee approved the application in accordance with the recommendation.
“Single storey extension to side and two storey rear extension, attic conversion with rear dormer. Demolish existing garage and construct new detached garage with associated retaining walls. (Resubmission of 25/0521/FUL). Bryn Ifor, Mountain Ash, Rhondda Cynon Taf, CF45 3AB”
“The Head of Planning presented the application to Committee and following consideration it was RESOLVED to approve the application in accordance with the recommendation of the Director, Prosperity and Development.”
