King Charles III has applied for planning permission to build a new greenhouse at his residence, Highgrove House in Gloucestershire, which he has owned since the 1980s.
The greenhouse will be 10ft high and have three "cold frames." The application states that the visual impact of the building will be minimal.
The greenhouse will also be used for the education of students on training programs offered by Highgrove Traditional Crafts.
The scheme is run by The Prince's Trust and is based at Barley Court, a restored 17th century farmhouse on the Highgrove estate.
The plans have been updated to move the structures further from the Grade-II listed main house, eliminating the need for listed building consent.
The Duchy of Cornwall has always managed the estate since it was purchased in 1980 for the then-Prince Charles.
The estate became
Prince William's when he became Prince of Wales and Duke of Cornwall following his father's accession.
