A new documentary is set to lift the lid on one of King Charles’ most private retreats, with never-before-seen footage filmed inside Highgrove House.
The Gloucestershire estate, which has been the monarch’s cherished countryside home for decades, is rarely shown beyond its gardens. However, a forthcoming Prime Video documentary offers a rare glimpse of the king moving through the house and grounds. And it’s clear it’s where he is most at ease.
The footage appears in Finding Harmony: A King’s Vision. The new documentary is launching on Prime Video on February 6, 2026. Ahead of its release, a teaser trailer has revealed intimate scenes of the monarch at Highgrove, both indoors and among the gardens he has lovingly developed over the years.

Inside King Charles’ Highgrove House
In the clips, King Charles can be seen strolling through the gardens in bright sunshine. He’s walking through the estate’s Arboretum with a shepherd’s crook, and spending time in the kitchen garden, recognisable by its famous pink door.
The trailer also highlights his vegetable patches, reflecting a passion for gardening that dates back to his childhood. He has previously spoken about growing up with his sister, Princess Anne, and the time they spent gardening on palace grounds.
Alongside the visuals, the documentary features audio of Charles speaking over several decades about the environment, agriculture and his long-standing commitment to sustainability.
Highgrove House has been owned by the king since 1980. He and Queen Camilla regularly retreat there to escape to the countryside. The estate is said to be worth around £28 million, according to Forbes.
While the gardens are open to the public on selected dates throughout the year, the house itself remains a private royal residence. Over the years, the gardens have been extensively transformed under Charles’ guidance.
