Applicant James Powell wants to build two holiday cabins with associated road improvements, and parking at land known as Cwm Mule at Dolfor.
The site is just off the B4355 road which eventually leads to Knighton.
The cabins will have toilets connected to a new septic tank.
Agent, Gerallt Davies of Roger Parry and Partners explained the proposal in a planning statement.
Mr Davies said: “The proposed site is currently a field.
“The applicant proposed the holiday development as a form of diversification and economic development.
“It is situated in an area where tourism is very popular, where the landscape, public footpaths are popular and therefore this sustainable method of accommodation will work well.”
“The proposal will provide a holiday let site, which will in turn provide the applicant with the additional income stream, support the the local tourism iof the area and indirectly support local businesses and sites where visitors will visit.”
Mr Davies added that hedgerows and trees at the site would mean the development would have a low visual impact on the area.
Mr Davies, said: “The low lying nature of the holiday lets and the existing landscaping means that landscaping means the holiday lets will be screened from the roadside and views.
“The proposed scheme has been specifically designed to be minimal, in that the cabins are small scale and low impact, and the number is considered to be low to fit in with the proposed venture”
“Tourism is a vital component of Powys’ economy.
“Powys’ beautiful countryside combined with it’s history and culture attract a vast amount of tourist activity.”
Mr Davies added that the road junction improvements would improve visibility in both directions.
A decision on the application will be made at a future date.
