Rear house extension at Strade, 65 Cae Gwyn, Caernarfon
Summary of planning committee decision
Decided by Gwynedd Planning Committee on 29 Sept 2025.
What was proposed
The application proposed demolishing an existing sun-room and building a one-storey, flat-roof rear extension with timber cladding, windows and bifold doors.
“Proposal: To demolish an existing sun-room and construct a new extension to the rear…”
“Description: An application to demolish an existing sun-room and construct a one-storey extension in its place at the rear of the property. The proposed rear extension will have a flat roof and measure approximately 8.4m x 4.8m. There is an intention to finish the extension with timber cladding.”
Officer report
The officer recommendation
Officers recommended approval because the design, appearance, residential amenity, biodiversity and Welsh language impacts were considered acceptable.
“It is seen that this site is within the development boundary in a residential area where there are many residential developments and are diverse in terms of their size and appearance. This proposal involves constructing a one-storey flat roof extension to the rear of the property. It is not considered that this proposal would harm the existing appearance of the site or cause excessive disruption on the area's visual amenities in general.”
“It is noted that there are some specific types of developments where it will be required for the proposal to submit a Welsh Language Statement or a Welsh Language Impact Assessment. The thresholds in terms of when it is expected to submit a Statement/Report have been highlighted in Policy PS1 of the Joint LDP, along with Diagram 5 of the SPG.”
Officer report
Consultation responses
The community council supported the application, Welsh Water provided guidance, and no correspondence was received from nearby residents.
“Community Council: Support the application.”
“Welsh Water: Observations and guidelines for the applicant in their letter dated 06/08/2025 Public Consultation: A notice was posted on the site and nearby residents were notified. The advertising period ended, and no correspondence was received regarding the development.”
Officer report
Committee discussion
Members were told that the extension measured 4.8 metres and therefore required a committee decision rather than relying on the stated permitted development rights.
“In response to a question on Householders’ Permitted Development Rights and that those rights permitted extending by up to 4m and why then was the application submitted to the committee, it was noted that the extension measured 4.8 metres and therefore needed to be submitted to the committee for a decision.”

The committee approved the application with conditions covering the work deadline, approved plans, green infrastructure statement and Welsh Water information.
“RESOLVED: To approve with conditions 1. Five years to commence the work 2. In accordance with plans 3. In accordance with the green infrastructure statement Information Note: Welsh Water…”
