The ultimate billionaire's rec room for only HK$340 million

Often located in the basements of standalone houses, rec (recreation) rooms are usually the play dens of many a teenage boy or bachelor, and a place they can get together with friends, kick back and have fun. While the rec rooms of most folks usually involve a comfy old couch and television, and maybe table tennis and a dartboard, Gettys Hong Kong imagines what a billionaire's rec room might look like. Think James Bond, Austin Powers, or perhaps Leonardo Di Caprio in .

According to Ariane Steinbeck, Gettys' managing director and principal architect, wealthy homeowners are looking for unique, tailor-made and immersive environments that provide an escape from reality and a break from the stress of day-to-day life. This ultimate recreational environment would have to be a collaborative effort between interior designers, audio-visual specialists, lighting designers, gaming developers and artists. Technology will play a big part, so the user can interact with varying surfaces for a multisensory experience.

Gettys' proposal includes four zones. The first zone consists of an entrance hallway of interactive walls that Gettys designed with the help of London-based artists and design collaborative Haberdashery. This interactive corridor leads the user through a tunnel-like path, which opens either to a projection/performance room or a bowling alley. "This entrance hallway is a space where an art and light installation would be used to enhance the experience and acts as a starting point for the journey into the gaming world, much like the procession of players from locker rooms to stadiums at the beginning of a game," Steinbeck says. The projection/performance room can be used for screening films, as a live performance venue, the landscape for a video game, or a party venue. This room comes with high-end digital screens and vintage sporting gear and sport memorabilia.

The second zone is a bar where luxury and technology meet. Bespoke furnishings from brands like Promemoria, Studio FormaFantasma and Achille Salvagni, and interactive surfaces are used to create spaces that encourage complete relaxation.

"In this space are a combination of windows and screens that will allow the user a view to the outside world. The screens can project anything they want, including television shows or sports matches," says Ramela Ouzounian, senior project designer at Gettys.

Next to the bar is a zero-gravity balcony - a glass room where one can experience what it's like to float in space, and the sensation of free falling, which feels like skydiving.

Moving from the bar down a large ceremonial staircase, one arrives at the third zone, where a rock-climbing wall and cave, as well as a classic arcade room with a pool table, video games and a half-pipe for extreme sports, beckon.
