Charles’s secret sanctuary: inside the king’s environmental obsession

King Charles III’s Highgrove House isn’t just a palace; it’s a living laboratory – and a deeply personal reflection of his unwavering commitment to the environment.

A retreat rooted in conservation

Far removed from the formality of Buckingham Palace, Highgrove, acquired in 1980, has evolved into a testament to the Prince of Wales’s evolving ideas. It’s a place where sustainable farming, traditional architecture, and a profound respect for the natural world are not ideals, but lived realities.

Beyond the grandeur: a smaller, deeper story

While the monarchy’s headquarters remain at Buckingham Palace and Clarence House, Charles and Camilla’s preferred residence in London is a far more intimate space – Highgrove. And it’s here, amidst the expansive 900-acre estate, that the seeds of his environmental philosophy were sown, particularly during his time with Princess Diana and their sons, Princes William and Harry.

Built in the late 1700s, the Georgian Neoclassical style, designed by Anthony Keck, deliberately eschewed the ostentation of other royal residences. Instead, it’s a relatively modest Home, prioritizing functionality and a connection to the land.

But don't mistake size for lack of impact. Highgrove is a deliberate statement – a tangible demonstration of Charles’s vision for a more sustainable future. Today, the estate utilizes solar panels, natural wastewater filtration, and an energy-efficient infrastructure, alongside Home Farm, a fully organic farm established in 1985.

A gardener’s testament

The gardens themselves are a marvel, transformed over decades by Charles and renowned horticulturalists. What began as pastures and a neglected kitchen garden has blossomed into a collection of interconnected spaces, attracting approximately 40,000 visitors annually. As Charles himself put it, “The garden at Highgrove really does spring from my heart and, strange as it may seem to some, creating it has been rather like a form of worship.”

Highlights include the Cottage Garden, a collaboration with the late Rosemary Verey, and the intricately designed Sundial Garden. Even more secluded is the Sanctuary, built in 1999 from Highgrove clay and barley straw, a testament to Charles’s dedication to biodiversity – a meadow teeming with 120 plant species and supporting dozens of beehives. Seeds from 27 native wildflower species are meticulously preserved in Svalbard, Norway.

The estate’s operations are remarkably sustainable, with composting systems converting garden and kitchen waste and renewable energy powering the property. It’s a continuous process of learning and experimentation, driven by Charles’s deep connection to the land. 'One of my great joys is to see the pleasure that the garden can bring to many of the visitors and that everybody seems to find some part of it that is special to them,' he remarked.

A legacy in the making

Now that Prince William has inherited the Duchy of Cornwall, Highgrove remains the King’s private country Home. It’s a place where his environmental vision continues to take root, a quiet corner of the British monarchy dedicated to a future where sustainability isn't a trend, but a way of life.
