Two-storey side extension at Lower Glyn Farm Road From Ty Du Road To Nex Common The Glyn, Devauden
Summary of planning committee decision
Decided by Monmouthshire Planning Committee on 14 Apr 2026.
What was proposed
Planning permission was sought for a two-storey side extension creating an L-shaped addition to the existing farmhouse.
“Planning permission is sought for a two-storey side extension, which will create an 'L' shape (the farmhouse as existing is linear with outbuildings to the side which is where the two-storey extension will be).”
Officer report
The site and its setting
The detached farmhouse is in open countryside within the Wye Valley AONB, with public rights of way around the site.
“This application relates to a detached farmhouse, known as Lower Glyn Farm, which is located within the semi-rural community of Devauden. The site is not within a development boundary as identified within the Local Development Plan; therefore the site is considered to be within the open countryside. The site is within the Wye Valley AONB and has public rights of way all around the site.”
Officer report
Why officers supported it
Officers considered the extension subordinate, well designed and respectful of the farmhouse, landscape, residential amenity and biodiversity.
“The farmhouse can be seen on maps dating from 1846, but it is likely to date back further. The property is a traditional Monmouthshire farmhouse and is considered to be an exceptional example of its type. Therefore, any extension should be carefully considered. The farmhouse is linear with adjoining outbuildings, previously likely used for animals/hay storage. The existing building features a natural slate roof and natural stonework on the external elevations.”
“As the building is of traditional nature, the extensions are subservient and considered to respect the form of the dwelling. In terms of size, the increase to the existing volume (913m³) would be 231 m 3 which would see a percentage increase in volume of 23%.”
Officer report
Consultation responses
The community council objected, while rights of way, trees and biodiversity consultees raised no objection, with biodiversity conditions requested.
“MCC Public Rights of Way (PROW): No objection.”
“MCC Biodiversity: No objection, subject to conditions.”
Officer report
Local concerns
A local member requested committee consideration because of concerns about the extension’s scale, the traditional farmhouse and its sensitive landscape setting.
“- A site notice was placed near the site. No comments have been provided during the consultation period.”
“County Councillor Rachel Buckler - I am requesting that this application goes before the full planning committee for consideration. Material grounds are that the scale of this extension is inappropriate in the setting of a historically significant traditional farmhouse and traditional farm buildings. Its setting in an area within the National Landscape means that it is particularly sensitive.”
Officer report
Committee consideration
Members considered the application details, late correspondence and the views expressed before a proposal to approve was made and seconded.
“We considered the report of the application and late correspondence which was recommended for approval subject to the conditions outlined in the report.”
“In noting the detail of the application and the views expressed, it was proposed by County Councillor Su McConnel and seconded by County Councillor Emma Bryn that application DM/2025/01483 be approved subject to the conditions outlined in the report.”
