Harry and Meghan might also find themselves the new owners of a country residence.
After the Duke and Duchess of Cambridge married, the Queen gifted them Anmer Hall, a 10-bedroom Grade II-listed mansion on the Sandringham estate, providing them with a bolt-hole in Norfolk.
Harewood Park near Ross on Wye, which was renovated after being acquired by the Prince of Wales's Duchy of Cornwall in 2000, could be contender for Harry and Ms Markle.
It was thought to have initially been earmarked for William and Kate.
Charles oversaw plans for the eco-friendly six-bedroom mansion featuring solar panels and walls insulated with sheep's wool.
Harry and Meghan might later move next to William and Kate, into the Duke and Duchess of Gloucester's apartment, as previously suggested by Princess Michael of Kent.
Princess Michael told Tatler: "(The Gloucesters) are rattling around this huge space and I think Prince Harry might go there, then they'd be next door to each other - very good move."
The royal couple could also find sanctuary on the private Balmoral estate in summer and the Sandringham estate at Christmas.
