The Duchess showed one of the reception rooms in the property while on a video call. In the video held in honour of World Osteoporosis Day, she is seen wearing a navy blazer jacket and a button-up white shirt.
The room shown in the clip featured light green walls and a marble fireplace behind the Duchess’ desk.
Other decorative elements included pink curtains that matched a gold floor lamp with a pink lampshade.
The video of the Duchess address was posted on the Royal Osteoporosis Society’s Instagram.
In the clip, she opened up about her mother’s battle with the disease and urges others to take precautions.
She said: “In those dark old days it was seldom discussed, rarely diagnosed and usually attributed to old women with so-called ‘dowager’s humps.
“My family and I knew nothing about it and were at a loss to know how we could help alleviate the terrible pain she suffered.
She added: “But how times have changed—today huge strides have been made in the treatment and research into osteoporosis, and we now know how it can be prevented and how we can support those who are living with it.
“We know it is vital to eat the right food, to take regular and weight-bearing exercise and, so importantly, to educate young people as to how to look after their bone health.
“It has, of course, been more challenging to get out and about this year, but we must all ensure, for the sake of our bones, that we stay as active as possible, even in the midst of a pandemic.”
The Duchess has been the president of the Royal Osteoporosis Society since 2001.
On Tuesday, she hosted a tea at Clarence House dedicated to representatives and supporters of the Royal Osteoporosis Society.
Craig Jones, the charity’s chief executive, said: “We warmly welcome this message of support from Her Royal Highness the Duchess of Cornwall.

“Osteoporosis affects 3.5 million in the UK but is much less well understood than other major health conditions.
“Crucially, the health of your bones can be improved throughout life by a healthy diet, regular exercise and vitamin D.”
Camilla had often spoken about the importance of practicing physical activities, even revealing her own activity regime.
She said: “I do a combination of a bit of Silver Swans and a bit of Pilates and a lot of walking which I love. We’ve all got to keep active.
“If we don’t we’ll seize up and won’t be able to get out of bed in the morning.”
Joking about her dancing skills, the Duchess added: “I’m very, very much a beginner and probably will always remain a beginner, but I do feel after a year, or 18 months, of doing it that maybe I’ve improved a tiny bit.
“But I’m certainly not going to be taking to the stage.
“I shall keep it in my own home very privately.”
