A controversial Newport house, branded an “eyesore” and “monstrosity” by locals, could be demolished following a decision by National Park planners this morning.

After a lengthy debate and representations from a number of speakers, members of the Authority’s Development Management Committee voted to refuse a retrospective application for Bettws Newydd on the Parrog.

Permission was granted for a dwelling at this site in 2006, but the house was built bigger than the approved application and in the wrong place on the site.

The retrospective application included landscaping plans to minimise the visual impact of the building.

The vote was nine to five in favour of refusal, which went against the planning officer’s recommendation, and enforcement action will now be implemented.

After the meeting, Robin Williams, who spoke on behalf of applicant Nolan Nicholas, said an appeal would be lodged against the decision. He said: “That’s democracy. We plan to appeal straight away. “Members took into everything into account in accordance with their instincts, that’s the planning process.”

Members of the Bettws Newydd Opposition Group welcomed the decision.

A spokesman said: “We are delighted with the outcome, and congratulate all the members who contributed to a well informed debate.”
