From Bill Gates' trampoline room to John Travolta's personal airport: Celebrities who have bizarre features in their homes

Money doesn’t just buy bigger houses, it buys audacity with no limits. When you’ve already checked off infinity pools, walk-in closets, and home gyms, the next step is getting weird in very specific, very personal ways. For celebrities, homes often become extensions of their obsessions, hobbies, and inner worlds. Some build spaces for their pets. Others build runways, underground tunnels, or full-blown amusement parks. These aren’t design choices made to impress guests, they’re built because they can. And once you start looking, you realise luxury doesn’t always mean subtle. Sometimes, it means a trampoline room, a nightclub, or a private airport in your backyard. Paris Hilton didn’t just spoil her dogs, she gave them real estate. In the garden of her Los Angeles home sits a miniature mansion designed specifically for her pets. Modeled after her own luxury house, it includes air conditioning, a balcony, and even a chandelier. The tiny palace reportedly cost around $325,000. It’s less “doghouse” and more Beverly Hills starter home, for chihuahuas.No actual bats here, but Lady Gaga’s home includes a hidden underground space accessed through tunnels. The area features a movie theatre, bowling alley, and arcade games. The property previously belonged to someone connected to Warner Bros., which explains the cinematic scale. It’s equal parts secret lair and entertainment bunker, very on brand for Gaga.John Travolta’s love for aviation goes far beyond a hobby. His Ocala, Florida home sits inside Jumbolair Aviation Estates and comes with its own runway. The $10 million property allows him to park two jets right outside his house, meaning he can step out his front door and onto a plane within minutes. For Travolta, traffic is never an issue.Before moving to Las Vegas, Céline Dion lived in a sprawling Florida estate that came with its own private water park. Built on a five-acre plot she purchased with her late husband René Angélil in 2008, the home featured slides and pools designed for family life. It was less rock-star excess and more “ultimate childhood dream,” especially for her three sons.Their Bel-Air mansion already comes with pools, gyms, and sweeping views, but one standout feature is a dedicated art gallery. Designed by architect Tadao Ando, the space houses works by artists like Andy Warhol and Jean-Michel Basquiat. Fun fact: their nearly $90 million purchase was the most expensive real estate transaction in the area at the time.Kris Jenner has a room. Just for plates. Her dedicated crockery space displays fine china sourced from around the world, including designer pieces like a $640 Gucci teapot. Everything is immaculately arranged, of course. It’s not a kitchen extension, it’s a museum for dishes, and somehow, it makes perfect sense for the Kardashian-Jenner matriarch.When Big Sean bought his Beverly Hills home, it already came with a nightclub, and he kept it. The all-black room features a DJ booth, disco ball, and skull-shaped wall lights. He showed it off in Architectural Digest, proving that some celebrities don’t leave the party behind, they just move it downstairs.Michael Jackson’s Neverland Ranch wasn’t just a home, it was a theme park. Located in Santa Barbara County, the estate once featured a rollercoaster, Ferris wheel, carousel, and bumper cars. The property has since been renamed Sycamore Valley Ranch and is now owned by investor Ron Burkle, but its legacy remains unmatched.Bill Gates’ home, known as Xanadu 2.0, is a $130 million high-tech mansion where rooms adjust to guests’ preferences. But one of its most unexpected features is an indoor trampoline room. Outdoor trampolines are common, indoor ones in billionaire smart homes are not. It’s a reminder that even tech moguls like to bounce.Not flashy, but deeply personal. On Blake Shelton’s Oklahoma ranch, the couple built a small private chapel where they later got married. It’s a quiet, meaningful space surrounded by nature, far removed from Hollywood chaos. Between gardening and country living, it’s one of the most grounded celebrity home features on this list.
