Applicant James Powell wants to build two holiday cabins with associated road improvements, and parking at land known as Cwm Mule at Dolfor, near Newtown.
The site is just off the B4355 road to Knighton. 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 of 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.
“Tourism is a vital component of Powys’ economy,” he added.
“Powys’ beautiful countryside combined with it’s history and culture attract a vast amount of tourist activity.”
The application says the cabins will have toilets connected to a new septic tank.
