Savills is marketing Havilland Hall, a historic mansion that once served as the official residence of Guernsey’s lieutenant‑governors, for £65 million.

The property occupies roughly 80 acres and includes six bedrooms, seven bathrooms, five reception rooms and an indoor swimming pool, making it the island’s largest private estate.

Construction of the main Regency villa was carried out between 1829 and 1830 by Lieutenant‑Colonel Thomas Fiott de Havilland, after which it became the lieutenant‑governors’ residence.

Previous owners have included marmalade entrepreneur William Keiller, whose family launched the first commercial Dundee marmalade brand, and Count Lothair Blücher von Wahlstatt, whose lineage traces to the Prussian commander at the Battle of Waterloo.

The estate also comprises formal gardens, parkland, agricultural land, five guest cottages, staff accommodation, office space, converted farm buildings, a wine cellar and a games room.

Savills’ country‑department head Phillippa Dalby‑Welsh described the property as a pre‑eminent Channel Island estate with a distinguished Regency villa and infrastructure capable of supporting a business operation.

Nick Paluch, head of Savills’ Guernsey open‑market residential business, called the offering a once‑in‑a‑generation opportunity.

The agency noted that estates of this scale are extraordinarily rare in the Channel Islands and expect interest from a global pool of potential buyers.
