A call to rebuild a fire-damaged Pembrokeshire farm building, as a family home to help manage one of the largest sheep flocks in Wales, has been given the go-ahead.

In an application to the Pembrokeshire Coast National Park Authority, D B Davies and Sons through agent Harries Planning Design Management, with a supporting statement by Reading Agricultural Consultants Ltd, sought permission to renovate an existing fire-damaged dwelling, together with the conversion and extension of outbuildings to form an agricultural worker’s dwelling at Mynydd Du, Rosebush.

The supporting statement through Reading Agricultural Consultants Ltd said Mynydd Du is part of a wider holding which includes Eisteddfa Fawr and land around the village of Brynberian, the farms approximately six km apart, with land under control of the applicant amounting to some 1,500 acres, with a further 3,000 acres of Preseli mountain common land also used; the land accommodating a 5,000-ewe flock with 10 suckler cows and followers.

It said DB Davies & Sons Unlimited, has five partners: the two Davies brothers, Berian and Ken; their wives; and Berian’s son, Dyfed.

Berian and Ken are in their late 70s, with most of the heavy work on the farm is undertaken by Dyfed.

Dyfed and his wife Megan are first language Welsh speakers, living some 10 km away in Nevern, while Berian and Ken, and their wives, live at Eisteddfa Fawr, Brynberian.

The dwelling at Mynydd Du, where most sheep are now wintered, is structurally sound and repairable but has been unoccupied since 1990, and was subject to arson circa 2013, the statement said.

It added Dyfed works full-time on the farm, alone with increasing frequency as the older business members are above retirement age, working “long hours out of necessity to undertake all the work associated with one of the largest flocks of sheep in Wales”.

“His working hours are extended further due to the fact that he lives remote (6kms) from the main block of land at Tyllosg, where Mynydd Du is situated in the centre of the farm. Travelling back and forth several times each day during lambing and other times during poor weather, to check on flock welfare is an arduous task and can be dangerous, particularly if driving when tired during inclement conditions.”

The statement added: “The application seeks permission to repair the fire damaged dwelling at Mynydd Du and bring it back to serve a useful purpose to enable Dyfed to closely monitor the ewes, not only at lambing, but throughout the year when the flock is grazing on the adjacent common land.

“It will also enable Dyfed to be with his partner and young child on a more regular basis than simply at the end of a long day when he is away from their current home, tending the sheep at Mynydd Du.”

An officer report recommending approval said: “When the application was first submitted, concerns were raised by officers in relation to the scale and design of the resultant dwelling.

“However, following discussions between the agent for the application and officers, amended plans have been submitted, with the scale and design now deemed to be acceptable.”

It said that applicant has submitted a rural enterprise dwelling appraisal outlining the need for the dwelling, with each test passed showing “there is an identified need for the agricultural worker’s dwelling”.
