Weybourne Holdings
Weybourne Holdings was formed in 2019. Sir James Dyson is its beneficial owner. The structure sits alongside two Dyson family foundations that handle separate philanthropic activity. The firm concentrates on direct real estate ownership, agricultural land and operating companies. Confirmed holdings include Dodington Park Estate in Gloucestershire, a Chelsea residence, The Village mixed-use assets in Fitzrovia, and Hullavington Airfield. It also controls Dyson Farming through New Beeswax Dyson Farming Limited and maintains a 100 percent interest in Dyson Holdings. Geographic reach covers the United Kingdom and the United States. The portfolio further includes two Gulfstream G650ER aircraft and the 91-meter steam yacht Nahlin. A limited partnership interest exists in WestRiver Mezzanine Loans Co-Investment Fund. The team includes CIO Jane Simpson and Head of Family Office James Bucknall. Additional directors are Jacob Dyson and Sam Dyson. Advisory board members comprise Tan Su Shan of DBS Bank and Koh Boon Hwee, chairman of SGX. June 2025: Tan Su Shan spoke at Ecosperity Week 2025 in Singapore on sustainability and investment strategy. The firm retains PwC as auditor and Lombard Odier as private banker. Weybourne Holdings operates as the central holding company for Dyson family operating assets rather than a conventional fund-of-funds allocator. Ownership flows through Weybourne Holdings Pte Ltd, which sits outside the two charitable entities that manage the family's grant-making.
