The cottage is a short walk from Frogmore House, which is used by the Royal family for private and public events, and Frogmore Cottage, previously used by the Duke and Duchess of Sussex.
It is thought the cottage was previously used by the estate’s dairy maid.
Its ground floor has most recently been used as a commercial unit and the first floor used as a residence.
Feilden+Mawson architects, for the RHPS, said it now needs a “full refurbishment throughout”.
The dairy, which is linked to the cottage, was built under the direction of Prince Albert in 1848 and designed in a Renaissance style.
The BBC’s Countryfile filmed the Royal Dairy, external for the first time for a show in 2018 to mark the 65th anniversary of Queen Elizabeth II’s coronation and 30 years of the programme.
