Thorngrove Manor
Adelaide, Australia · Independent · High Luxury
Thorngrove takes one couple at a time, and the owners promise you will never see another guest. Kenneth Lehmann, owner, builder and architect, raised the turreted castle with his wife Nydia from 1984, on a piece of the old Derrymor Estate in Stirling, twenty minutes from Adelaide in South Australia's oldest wine region. Dinner arrives on eighteenth-century hallmarked sterling silver, in the suite or by candlelight. Michelin has given the house Two Keys in 2025 and in 2026. After twenty-eight years with Small Luxury Hotels of the World, the Lehmanns left the group in 2024.

About Thorngrove Manor
- Kenneth Lehmann began planning a small hotel in 1977. In 1984 he and Nydia bought this Stirling parcel, once part of Derrymor Estate, and built the castle themselves.
- Meals are served in the suite or, if you reserve it, in a candlelit dining room of your own. The house is turrets, towers and rough stone.
- The bookable rooms include the Observatory, the Queen's Chambers, the Castle Chambers and a Tower Room. The King's Chambers is off the list for now.
- Guests need to climb stairs, and the house has no step-free route through the turrets and tower rooms.
- Before leaving Small Luxury Hotels of the World in 2024, the manor had been a member for twenty-eight years and had just posted a 96.4 percent mystery-inspection score.
History
Thorngrove Manor is a castle-like hotel in the Adelaide Hills village of Stirling, conceived, designed and built by owners Kenneth and Nydia Lehmann, who began construction in 1984. Turrets, towers and rough stone walls make it a deliberate European-castle fantasy, filled with hand-crafted detail and antiques.
The house now accepts one adult couple at a time and does not take groups or events. It belonged to Small Luxury Hotels of the World for twenty-eight years, then left the group in 2024. Michelin has awarded Two Keys in 2025 and 2026.
