A pocket of leafy suburban London that once held a secret, wartime intelligence base with bullet-proof doors and windows, and wireless transmitters on the roof, is now a newly built luxury home.

Set in the village of Arkley in North London, Rowley Ridge, as it’s known, spans 1020 square metres and hit the market in April for £8.5 million (A$15.4 million) with estate agency Beauchamp Estates.

During World War II, the site of Rowley Ridge—then an Edwardian villa—was selected by British Prime Minister Winston Churchill as one of a handful of detached country houses to be a clandestine listening post base used by M16 to spy on German signals, intercept illicit wireless messages and support the code-breaking taking place at the famed Bletchley Park, according to a news release from the brokerage.

Set 134-metres above sea level, Arkley was chosen by Churchill for its advantageous altitude—conductive for capturing radio transmissions.

“As a local resident I am naturally biased, but I truly believe that Arkley is a true leafy oasis,” Jeremy Gee, managing director of Beauchamp Estates said in the release.

It’s “one of London’s most exclusive enclaves, bordered by both greenbelt countryside and the private golf course, yet only nine miles from London’s West End,” he said. Arkley’s hidden role as a World War II M16 base adds the excitement and glamour of the secret services, spies and gadgets.”

Now the six-bedroom family-home, developed by Domvs London—is loaded with very different amenities than it would have housed some 80 years ago.

There’s a three-story atrium, a main reception room with a lounge area, drawing room area and dining area, a custom-designed kitchen, a main bedroom suite with a private balcony and views across the nearby private golf course, according to the release.

On the basement level is a soundproof cinema room with a cocktail bar, a game room, a swimming pool, a steam room and a gym. There’s also a panic room and a biometric entry system.

Idaho is not a place that’s often associated with Medieval castles, but a pair have just hit the market for $6.25 million.

The imposing stone structures have towers, turrets, ramparts, arrow-slit windows and even a drawbridge, and might just be the most authentic-looking castles this side of the Atlantic.

“Who expects to see a castle like this in Idaho?” said listing agent Brenda Burk of Coldwell Banker Schneidmiller Realty, who brought the property to the market last week. They are, she said, “extremely unusual.”

Schweitzer Castle and Château de Melusine, as they’re known, stand within Schweitzer Mountain Resort in the Selkirk Mountains and overlook the nearby mountain resort town of Sandpoint. They take in panoramic views of Lake Pend Oreille, Idaho’s largest lake.

The pair of ski-in/ski-out homes each have three bedrooms, two bathrooms and three stories, Burk explained. They are “so authentic,” she said. “Every single stone was handlaid.”

Schweitzer Castle, she said, wasn’t built for “functionality,” but has been modernized and adapted and now has everything a 21st-century residence requires, along with a dungeon, which for some buyers may also be a requisite.

The chateau, meanwhile, has a hot tub room with mountain views, as well as a garage.

The property is being sold furnished, and will come complete with the hand-carved statues, armor, mounted swords, stained-glass windows and a host of antiques dating to the 15th and 16th centuries.

The owner, an antique collector who couldn’t be reached for comment, “is always looking for that hidden jewel and he found that here,” Burk said.

The next custodian is likely to stem from a varied pool of buyers, Burk said, that would include “the trophy-home buyer, someone who can say ‘I own a castle.’”

The property could also appeal to someone looking for a vacation home, or a multi-generational estate, and beyond that “there’s the dreamers,” she said. “We definitely try to market to people who like Medieval history or maybe do Renaissance fairs.”

The seller “really wants it to go to someone with the same passion.”
