Two private Thames islands linked to Edward VIII head to auction for £1.65m

Two private islands on the River Thames, once linked to the secret courtship of UK's King Edward VIII and Wallis Simpson, are heading to auction after failing to find a buyer at a higher asking price last year. The unusual estate, which combines privacy, history and riverfront views, is now expected to fetch £1.65 million when it goes under the hammer on July 28, 2026.A royal-linked retreatHolm Island and Hollyhock Island sit on the River Thames in Wraysbury, Berkshire, around 20 miles west of central London. The two islands are connected by a footbridge and have long been tied to one of the most famous romances in British royal history. During the early 1930s, Hollyhock Island is said to have been home to a small cottage known as The Nest, where the future Edward VIII met Wallis Simpson in relative secrecy.Their relationship later made headlines around the world and ultimately reshaped the monarchy. Edward abdicated the throne in 1936, less than a year after his coronation, so he could marry Simpson, the twice-divorced American socialite. That dramatic chapter gives the islands an unusual place in royal history, turning a private riverside escape into a property with enduring intrigue.What is on the marketThe sale includes nearly 2.9 acres of land across the two islands, with Holm Island serving as the main residential base. At the centre of the estate is a five-bedroom detached house of roughly 5,000 square feet, described as being in reasonable decorative order. The home has four bathrooms, oversized windows and balconies that look out over the river, giving the property a strong sense of openness despite its secluded setting.The islands are linked by a bridge and are being sold with vacant possession. Holm Island is accessed via a private driveway off the south side of Wraysbury Road and comes with ample private parking and garaging. The estate is also conveniently placed for Staines-upon-Thames, with shopping, transport and local amenities within easy reach, as per the details mentioned on Savills Auction's official website.Why it stands outPrivate islands close to London rarely come to market, and that is one of the main reasons this listing is drawing attention. Savills, which is handling the auction, says opportunities to buy not one but two private islands within commuting distance of the capital are exceptionally rare. That combination of location, scale and privacy makes the property unusual even by luxury-market standards.The guide price has also attracted interest because it marks a sharp drop from the £3 million asking price attached to the islands when they were previously listed for sale last year, as per reports. In other words, buyers are now being invited to consider a property with history, land and development potential at nearly half the earlier figure. For investors, end-users and anyone seeking a standout riverside home, that lower price could make the estate more accessible than before.Potential beyond the houseSavills has highlighted that the site offers further potential, subject to the necessary consents. That means the new owner may be able to enhance or reimagine parts of the estate, depending on planning approvals. The auction listing suggests the property could appeal not just to someone wanting a unique home, but also to developers or investors looking for long-term value in a scarce market.The surrounding area adds to the appeal. Staines-upon-Thames offers a practical base, while schools such as TASIS International School, ACS International School and Staines Preparatory School are within reach. Recreational spots including Staines Moor and Lammas Recreation Ground are also nearby, and Wentworth Golf Club as well as Berkshire and Guards Polo Clubs are accessible for those drawn to the local leisure scene.A rare chance for buyersRalph Mendes da Costa, a director at Savills Auctions, described the offering as extraordinary, as per reports. He said that chances to acquire two private islands so close to London are “extraordinarily rare” and added that Holm Island and Hollyhock Island combine privacy, green space and future potential in a way that creates a distinctive opportunity.The auction is scheduled to run from July 28 to 29, with the islands offered at a guide price of £1,650,000. Since the property has remained in the same ownership for more than 30 years, the sale marks the first time in decades that a buyer has had the chance to take on the entire estate.A property with a storyWhat makes this listing especially compelling is that it is not just about acreage, architecture or location. It is about atmosphere and memory. The islands carry the echo of a relationship that changed the course of British royal history, and that backstory gives the estate a character few other properties can match.At the same time, the practical side of the sale is equally important. A substantial detached home, private parking, garaging, river views and rare island ownership combine to create a high-end residential package with real flexibility. Whether the next owner wants a secluded home, a project with enhancement potential or simply a remarkable piece of the Thames, the estate offers something that is difficult to replicate.For buyers with the means and imagination to see beyond the price tag, these islands present a chance to own a fragment of royal-era history along one of Britain’s most famous waterways.Ready to Make a Smarter Property Decision?
