Havilland Hall, a former official residence of Guernsey’s lieutenant-governors with family links to Oscar-winning actresses Olivia de Havilland and Joan Fontaine, has gone on sale for £65m. Set in about 80 acres, it is being marketed as the island’s largest private estate.

The sale brings together nearly two centuries of history and a substantial collection of residential, leisure and working buildings. The main house alone provides more than 17,000 sq ft across four floors, with six bedrooms, seven bathrooms and five reception rooms.

Lieutenant-Colonel Thomas Fiott de Havilland built the hall between 1829 and 1830. It subsequently became the official residence of Guernsey’s lieutenant-governors. Later generations of the wider de Havilland family included aviation pioneer Sir Geoffrey de Havilland and the actresses Olivia de Havilland and Joan Fontaine; their connection is through the family rather than an established account of either sister living there.

Former owners included William Keiller, whose family created the first commercial Dundee marmalade brand. In 1922, the estate was bought by Count Lothair Blücher von Wahlstatt. His family traced its ancestry to the Prussian commander whose forces helped the Duke of Wellington defeat Napoleon at Waterloo.

Beyond the Regency villa, the estate includes five guest cottages, staff accommodation, offices and converted farm buildings. Formal gardens, parkland and agricultural land make up the grounds. Leisure facilities include an indoor swimming pool, a temperature-controlled wine cellar and tasting room, a games room, gym, sauna and steam room.

Savills is presenting the combination of land, accommodation and facilities as the property’s principal distinction. Phillippa Dalby-Welsh, head of its country department, described it as a “pre-eminent Channel Island estate” and highlighted infrastructure capable of supporting a business operation alongside the main home.

She said: “Estates of this scale are extraordinarily rare in the Channel Islands and it is likely to draw a global audience.” Nick Paluch, head of Savills’ Guernsey open market residential business, called it a “once in a generation opportunity”. Those are the selling agents’ assessments: the £65m listing has yet to establish what a buyer will pay.
