The roughly 20,000-square-foot property is notable for its unique underground tunnel that connects the estate to the ocean via a private beach.

Valve co-founder Gabe Newell has acquired a super mansion in Manalapan, Florida, for $70.8 million. The property, spanning approximately 20,000 square feet, includes an underground tunnel that connects the waterfront estate to the ocean via a private beach.
The luxurious residence features an outdoor pool, a dock, and a boat lift. Additional amenities include an eight-car garage, a wine cellar, dedicated guest quarters, and a wellness wing. Cindy and Ron McMackin, founders of Pan-Pacific Mechanical, were the previous owners, having purchased the estate for $39 million in 2020.
Newell, estimated to have a net worth of $11 billion, is a prominent figure in the video game industry. He co-founded Valve, the company behind the digital distribution platform Steam and successful game franchises such as Half-Life, Counter-Strike, and Dota.
In recent years, Newell has reportedly lived at sea, preferring his luxury yachts over a permanent residence near Valve's headquarters in Bellevue, Washington. His fleet includes the Leviathan, a flagship yacht equipped with an onboard hospital, lab, spa, and gaming stations. He also owns a shipyard and a research organization called Inkfish.
Newell has expressed enjoyment in his work, stating in a July interview that he works seven days a week from his superyacht. He engages in various projects, including AI development, Steam-related initiatives, and advanced research such as aerosol pathogen detection devices and brain-computer interfaces. He is also reportedly constructing a $230 million deep-sea research ship, slated for completion by 2028, designed to carry robots and scientists to map oceanic trenches.
According to IGN, the information regarding the mansion purchase was initially reported by the Wall Street Journal. Premier Estate Properties handled the sale of the Florida residence.
