A decision on plans to extend a house dubbed “more suited for Beverly Hills than Mynydd Nefyn” has been postponed.

When Gwynedd Council’s planning committee met on Monday it was asked to approve the refurbishment and extension of Tan-y-Mynydd. This follows the refusal last September of earlier proposals for the same property.

Members decided to delay any decision until the findings of the Llyn Area of Outstanding Natural Beauty Joint Advisory Committee are available.

Cllr Simon Glyn, a member of both the planning and AONB committees said an emergency meeting had been held in March to discuss the application, with detailed findings. Cllr Glyn argued its findings should be made available for planning committee members to consider in full before coming to a decision.

The amended plans involve the refurbishment and extension of the house, including demolishing an existing outbuilding, rear two-storey extension and a glass side extension.

Relocating a stone wall in order to create a parking and turning area, it would also see a new two-storey and another single-storey extension and a balcony on the gable-end of the existing house.

Last September, Cllr Gareth Jones described the “overbearing” plans as “suitable for the slopes of Beverly Hills but not Mynydd Nefyn”.

Councillor Gruff Williams told Monday’s committee that while officers felt amended plans were an “improvement,” on those refused last year, officers had also recommended approval back then.

He added the plans represented “clear damage to the Area of Outstanding Natural Beauty,” and would “set a precedent” for future applications.

“What we have here now is 19th century cottages associated with the works at Llithfaen and the area’s maritime tradition, but these plans represent gentrification.

“You only need to look at Plas Pistyll to see what happened to house prices there. Allowing these plans would simply open the floodgates to further gentrification.

“I urge you to refuse on the basis of several policies already listed and in order to protect the Area of Outstanding Natural Beauty.”

Lowri Jones, speaking on behalf of the applicants, stressed the property would not be used as a holiday home and spoke of the applicants’ fondness for the area and hope of setting up home there.

Adding the property had laid empty for years, it was not the intention of the applicants to create an eyesore.

Applicant Warren Hadlow said their previous application was “beset by a campaign of disinformation as to its size and ambition”.

Having amended the plans to use white render, he hoped it would ensure the property is “more in keeping with the existing surrounding buildings and true to the existing building”.

The decision to delay a decision until the next committee meeting was unanimously approved.
