One Palace Green joins an exclusive portfolio of properties lining Kensington Palace Gardens. 

Residential developments don’t get more exclusive than Kensington Palace Gardens, a.k.a. “Billionaires Row”. The latest addition, One Palace Green, is no exception. Brought to market by REDD Real Estate, this is one of London’s most significant surviving Arts & Crafts buildings.

Designed by pioneering architect Philip Webb as a London residence for the artist George Howard, later 9th Earl of Carlisle, and his wife Rosalind, the Grade II* listed building has been meticulously restored and returned to its original residential use.

The 19,200sq ft mansion that occupies a rare 0.25-acre plot at the end of Kensington Palace Gardens now comprises five apartments and a separate coach house, with prices starting at £15 million. Of course, amenities are more than up to scratch for a super prime residential development, including a five-star concierge service, a landscaped private garden, discreet security, as well as state-of-the-art heating and cooling systems – a true rarity for such an historic building.

Speaking about One Palace Green, Russell Smithers, CEO and Co-founder of REDD, says it “has all the ingredients that are almost impossible to bring together in London: an extraordinary history, exceptional architecture and a position on Kensington Palace Gardens.” Elaborating further, he comments: “We are living in a world where buyers value craftsmanship, authenticity, natural materials and things that have been made to last. Those were the principles behind this house when it was built, and they are just as important to its next chapter.”

Pilbrow & Partners designed the architecture, working with conservation architects Donald Insall Associates, and landscape architect Randle Siddeley designed the gardens. Martin Kemp Design led the interiors, carefully balancing original architecture with contemporary motifs. The palette draws on One Palace Green’s surroundings for inspiration – moss greens, soft stone, earth tones – while tactile linens, handcrafted ceramics and bespoke upholstery create a more relaxed atmosphere. Notably, thanks to the curation by Daniel Morris Art Advisory, three paintings by George Howard, believed to have been painted during his time at the property, now hang on the walls.

The Howards were famously part of the influential Holland Park Circle, a group of West London Victorian artists, architects and patrons. Their former home bears the traces of their peer’s talent. Nowhere is that more evident than the dining room, which combines the work of Webb, William Morris (who worked on the decorative scheme) and Edward Burne-Jones (who created his renowned Cupid and Psyche canvases). The dining room survives today and has been meticulously restored, serving as an allegory for One Palace Green itself – preservation that honours the past but leaves space for evolution.
