The King is running the risk of upsetting neighbours on the Sandringham Estate amid fears Charles's plans for a giant slurry pit could produce "unpleasant odours".
A huge lagoon with up to two million gallons of liquid manure is being backed by councillors, with documents revealing one of the nearest homes near the proposed building site is Anmer Hall, the Grade II-listed mansion of Prince William, Princess Kate and their three children.
The future King's Georgian house is just under a mile away, but locals fear that it will be subject to stink.
"We are all used to farmyard smells around here - but this lagoon will be enormous," one anonymous neighbour told The Mail.

They continued: "Everyone is worried it will create a massive stink. Goodness knows what William and Kate think about it.
"It is a bit ironic that the landowner responsible for the plans is William's father, the King."
King's Lynn and West Norfolk Borough Council is considering the scheme and options for giving it the green light.
Charles wants to excavate the pit to store animal waste, which can be spread as organic fertiliser on his field.

The parish council in Flitcham, around one mile away, has raised "valid concerns" about the proposition.
Clerk Gill Welham said at a recent parish meeting there were worries about "safety issues and unpleasant odours affecting the village if the wind was blowing this way".
Submitted plans by Sandringham Farms state the pit would be surrounded by plants and flowers.
Some of the manure will come from the King's sheep and cattle on the estate, but much of it will be transported to Sandringham.

The change is part of wider renovations that have been made to the 16th-century building, including replacing the "threadbare" red carpet in the congregation pews for a sum of £4,000.
Workers have also carried out the cleaning of the mosaic flooring and replaced the clock on the church tower.
The parish room, which is attached to the rectory, has also been given a revamp.

The total bill for the refurbishment came to £6,765 and is the responsibility of the Parochial Church Council.
Local resident Colin Smythe told Hello: "The squeaky floorboard was very irritating.
"Every time someone stepped on it, the solemn mood was ruined.
"It's great, it has now been repaired, so services will be more peaceful."
