A planning application for the Grade II-listed building - which sits on 35 acres of lush grounds - has been submitted to the council.

But a file note has been attached to their application, saying it contained "sensitive information" and therefore no forms or drawings would be publicly disclosed.

It further noted the secrecy around private planning applications were often regarding "security" of the home."

A Royal source told The Sun Online the total cost of the refurbishments would be publicly disclosed.

Is Meghan Markle and Kate Middleton rift causing tension between Harry and William and behind Windsor move?

It's not the first time the Royal Family has kept refurbishment plans private, with the Duke and Duchess of Cambridge also keeping the plans secret before moving into the Sandringham Estate manor.

The big move means the couple will be leaving their home in Kensington Palace they currently share with Prince William and Kate Middleton.

The couple had originally planned to move into one of the main apartments in Kensington Palace but a royal source said there had been "a bit of tension between the brothers" and that Meghan and Harry "wanted to strike out on their own".

Frogmore Cottage needs major building work to turn it back into a luxury family home, which will be funded by the taxpayer.

Cottage is a pretty modest way to describe the stunning property in the grounds of Windsor Castle.

The 10-bedroom home sits on 35 acres of lush land and is due to have a multi-million pound refit - paid for by the taxpayer - to transform it back into a luxurious family home complete with a new nursery, gym and yoga studio.

Currently it’s been chopped up into five units where palace staff have been living.

Kensington Palace released a statement saying: "The Duke and Duchess of Sussex will move to Frogmore Cottage on the Windsor Estate early next year as they prepare for the arrival of their first child."

Grade II-listed Frogmore House, formerly known as Double Garden Cottage, has been a popular royal hideaway for more than 300 years.

It's still used by the Queen and other members of the Royal Family as a retreat for private and official royal engagements.

The name was inspired by the large number of frogs that thrive in the low-lying, marshy Berkshire countryside that surrounds it.

In years gone by, members of the public could walk right up to the home, surrounded by a small fence with a sign reading "Private".

It is expected the refit of the property will include an extensive security upgrade before its new tenants arrive.

The statement from Kensington Palace claimed Windsor is a "very special place" for the Duke and Duchess of Sussex, after they tied the knot there in May this tear.

They held their wedding reception, hosted by the Prince of Wales, at Frogmore House, which was also where the couple's engagement photos were taken.

In 2008, Frogmore House hosted the wedding reception of Princess Anne's son Peter Phillips and his Canadian wife Autumn.

The estate boasts its own man-made lake, aptly named Frogmore Lake, and is home to the Royal Burial Ground and the tomb of Queen Victoria and Prince Albert.

Frogmore House was built in the 1680s by Hugh May, Charles II's architect, and bought by Queen Charlotte, wife of George III in 1792.

It later became home to Queen Victoria's mother, the Duchess of Kent, for almost 20 years and her remains are held there in a stunning mausoleum.

The house is currently open to the public for one month a year - August - with tickets costing £35 a person through the Royal Collection Trust.

The venue also hosts three charity open days.

Among the grand rooms at Frogmore House is one decorated by 18th-century flower painter Mary Moser, while Princess Elizabeth - the daughter of George III and Charlotte - painted garlands in The Cross Gallery.

The house features several watercolour paintings by Victoria's daughters, princesses Victoria and Louise.
