A north Pembrokeshire couple could be forced to tear down their self built eco-home, as planners look set to refuse retrospective permission.

Charlie Hague and Megan Williams have gained support from across the world for their fight to keep their unique roundhouse near Glandwr, but Pembrokeshire County Council’s planning officers have recommended the application is refused.

The development is due to be discussed by the council’s planning and rights of way committee on Tuesday morning.

The one bedroom house was built without planning permission, and was issued with an enforcement notice in December 2012. An appeal was lodged and dismissed in July 2013.

The officer’s report states: “The proposal represents an unjustified residential development in countryside contrary to the rural restraint policy of the Local Development Plan.”

It added: “Despite its relatively low visual impact it erodes the rural character of its surroundings and represents an unsustainable form of development in terms of distance from day to day facilities.”

Officers also state that the proposal ‘fails to demonstrate that it constitutes an exception’ under the One Planet Development initiative, which enhances environmental quality.

More than 90,000 people have so far signed an online petition supporting the couple’s application.
