The Grosvenor Group is reportedly looking to sell U.S. real estate assets worth £700 million, as the family behind the Duke And Duchess Of Westminster responds to a sharp downturn in the region. James Raynor said the portfolio would be sold “over a period of time,” after reported a £108 million loss in the region last year and a total revenue loss of £23.2 million across all global markets in 2025.

The reported move marks a rare public glimpse into the finances of one of Britain’s richest landed families, whose name is far better known for its property empire than for its public appearances. Hugh Grosvenor inherited his family’s 340-year-old fortune after the death of his father, Gerald Grosvenor, in 2016, and married Olivia Henson in 2024.

The Grosvenor Group website lists sites in Seattle, San Francisco, Los Angeles and Washington as well-connected locations with strong demographic and economic fundamentals, a sign of how deeply the company has been embedded in the U.S. market. Its wider holdings stretch far beyond America. The family owns 50 per cent of Mayfair and 300 acres in Belgravia in London, along with the Eaton Estate in Cheshire and the Abbeystead Estate in Lancashire. It also has estates in Scotland, Spain and Liverpool, plus a shopping centre in Stockholm, a residential tower in Tokyo, a large chunk of Silicon Valley and all of Annacis Island near Vancouver.

Those assets are held inside trusts, a structure put in place in the 1950s to shield the estate from spendthrift heirs, disastrous divorce and other threats. Hugi Clarke said the duke and his family receive the benefits but have no “absolute right” to the assets. That legal setup helps explain why the Grosvenor name can still project immense wealth while the group adjusts its portfolio in response to losses. The family’s recent public profile has also been unusually grounded: Hugh Grosvenor and Olivia Henson worked alongside the Chester FC Community Trust in April, and the Duke of Westminster opened the King George V Sports Hub in June 2022.

The sale underlines a simple fact about the duke’s fortune: even one of the country’s most powerful property dynasties can be forced to rebalance when its numbers turn south. The question now is not whether Grosvenor will sell, but how much of its U.S. footprint it is willing to let go.
