The Duke, 36, arrived at the property in Windsor on Friday to begin his five-days of self-isolation ahead of attending the unveiling of a statue of his late mother on July 1.
His grandmother, 95, was seen driving towards the Grade-II listed cottage on Friday evening, around 30 minutes after Prince Harry arrived from London Heathrow.
It is unlikely that the Queen had any contact with her grandson, as he is isolating.
Harry has travelled to Windsor from his home in Montecito, California, to join Prince William for the unveiling of a statue of Diana, Princess of Wales, in Kensington.
The ceremony, taking place on their late mother’s 60th birthday, has been scaled back due to Covid restrictions, with many of Diana’s friends unable to attend.

It will mark the first time Harry has both travelled to Britain and spent time with his brother since the Duke of Edinburgh’s funeral at Windsor Castle on April 17.
His wife Meghan Markle has remained at their £11million mansion in Montecito with two-year-old Archie and their second child, Lilibet Diana, who was born 21 days ago at Santa Barbara Cottage Hospital.
The Duke touched down at Heathrow at 12.38pm yesterday on a Boeing 777-323, which left Los Angeles International Airport on Thursday at about 7pm local time.
He later travelled to Frogmore Cottage in a Range Rover with a police escort, with protection officers earlier seen parked at the airport in a 2019 Volkswagen Caravelle worth £47,000.

Those arriving in England from amber list countries must typically quarantine for ten days, but can half this under ‘test to release’ if they pay for a Covid-19 test on day five, in addition to a test on day two.
Frogmore Cottage was initially gifted to Harry and Meghan by the Queen after the couple’s wedding in 2018.
However, they gave up the property after dramatically quitting frontline royal duties and moving to the US last year.
The keys were later handed to Princess Eugenie, who is living there with husband Jack Brooksbank and their recently born first child August.
Harry will reportedly be staying with the couple during his UK visit, with the space divided into two sections to make it Covid-safe, according to The Sun.
A Kensington Palace spokesman said yesterday: ‘Prince William and Prince Harry will attend a small event to mark the unveiling of a statue they commissioned of their mother, Diana, Princess of Wales, in the Sunken Garden at Kensington Palace on Thursday, July 1.

‘In addition to close family of Diana, Princess of Wales, members of the statue committee, the sculptor Ian Rank-Broadley, and garden designer, Pip Morrison, will also be present.
‘Further details about the statue and garden will be provided on July 1.’
It comes as the Daily Mail revealed how brothers William and Harry have had to drastically scale back the statue unveiling.
The brothers were due to put aside their bitter rift to host an elaborate ceremony on July 1 at Kensington Palace, her former home.
Instead they will preside over a significantly reduced gathering featuring just a handful of guests – the estranged princes themselves and Spencer relatives.
Up until this week they had been planning to welcome more than 100 of their mother’s friends, former staff and supporters. But Covid rules have pressed them into a rethink.

It is a bitter disappointment for many in Diana’s circle who had hoped their presence would help bring about a reconciliation between William and his brother.
They have been barely on speaking terms since Harry and Meghan quit royal life for California. Whether this makes a rapprochement that much easier remains to be seen.
The pair have privately told friends that they will do their utmost to ensure their differences do not distract from what they hope will be a moving celebration to recognise their mother’s ‘positive impact’.
Ever since they announced plans for the statue it has been bedevilled by problems. Originally it was hoped to be unveiled in 2017.
But there were delays over the design and, according to insiders, differences of opinion over what period in Diana’s life the statue should represent.
Such divisions led the committee – set up after her death in 1997 in order to find a suitable way to celebrate her life – to conclude that a statue would be wrong.
At the time, her family expressed reservations that no sculptor had ever properly ‘caught’ Diana. There were also real fears that a statue would become a shrine.
Those fears have not subsided but with the passing years, William and Harry felt the time was right for a life-size figure.
They sought private donations to fund the statue, which has been created by artist Ian Rank-Broadley, whose portrait of the Queen appears on all British coins.
The statue was finished in 2018, but Harry and Meghan’s wedding and Megxit delayed the unveiling.
Donors including Elton John and David Furnish will now be invited to September’s party along with other friends and family – but there is no guarantee Harry will be there.
