The most expensive home for sale in London is a $97 million mansion that has a panic room equipped with fingerprint and eye recognition. Here's a look inside.

A £75 million ($97 million) mansion has hit the market in London, becoming the most expensive residence for sale in the UK capital, Sotheby's International Realty confirmed to Business Insider.

The home sits behind a gate in the affluent residential neighborhood of St. John's Wood.

Sotheby's did not disclose the current owner of the home.

The lavishly decorated home has a double-height entrance hall. The grand hall features a stone staircase and a floor-to-ceiling chandelier.

Three bedroom suites sprawl across the home's first floor, with four more bedrooms on the second floor.

Every bedroom comes with an en-suite bathroom and dressing areas with built-in wardrobes.

The master bedroom suite has its own walk-in dressing room and two separate marble bathrooms.

In addition to its lavish bedroom suites, the home has staff living quarters that include three bedrooms, three bathrooms, a sitting room, and the catering kitchen.

There's a separate staff entrance and "discreet" service stairs, according to the listing.

Below the ground floor is a 46-foot swimming pool ...

The below-ground entertainment area also includes a 12-seat cinema and bar.

One of the home's standout amenities is the hydraulic car lift ...

... which lowers cars into an underground garage that can fit up to four vehicles.

Also beneath the home is a secure panic room with cameras of the entire house and biometric security technology measures such as fingerprint and eye recognition.

Sotheby's declined to offer any further details on the biometric security technology or panic room, but noted that such system can be upgraded and tailored to a buyer's particular needs.

Despite its high price tag and extensive array of amenities, even if the $97 million mansion sells at the asking price, it will not be the most expensive residence to ever sell in London.

That record is held by the sale of a country manor in Oxfordshire for £140 million ($183 million) in 2011, according to Mansion Global.

In 2019, billionaire hedge fund manager Ken Griffin paid $122 million for a London home in the city's most expensive sale since 2008.
