The Philips family have lodged a plan with Powys County Council to demolish a redundant farm building at Bryn Hunllef.
They want to replace it with a building of “similar size and scale” which would become a log cabin for letting to holiday makers.
Agent, Jason Green explained the proposal.
He said: “Mr and Mrs Philips own 14 acres and have this as a small holding.
“They would like to construct the holiday let cabins as a form of diversification from agriculture to a commercial use to subsidise their income as they are now at retirement age.
“The area that the cabins are to be built on is the site of a redundant agricultural building which is beyond economic repair for this purpose.
“That is not to say that it is derelict in anyway, just that in it’s present state it would be uneconomic to convert it into holiday lets.
Mr Green explained that development would bring money into the local economy and also creates two part time and one full time jobs.
He added: “This small development will encourage visitors to the area who may not visit at present due to a lack of self contained holiday lets.
“Some people especially with children would like their own space rather than staying in a hotel or a B&B.
“The local economy would be helped with visitors shopping locally and hopefully using the local public house and facilities in Llandrindod Wells, Rhayader, and the surrounding area.”
Mr Green said that the log cabins design would be “in keeping” with a rustic nature and that they interior would be “open plan”.
He also said that the current access to the building is of a “good standard” of rolled stone.
Mr Green, added: “The access is well established and has been used to the property before ir was purchased by Mr and Mrs Philips in the early 1980’s.
“We feel that the existing access is more than adequate in it’s present state.”
The plans will be decided at a future date.
