Behind multiple secured gates within Royal Oaks Country Club, this four-level steel-framed estate spans more than 20,900 square feet and was previously featured on MTV Cribs and owned by NBA legend Nick Van Exel. Designed by architect Paul Olson with interiors by Steven G. and Marc-Michaels, the residence includes over $16 million in enhancements, the largest single-family residential door in the United States at the time of construction, 72 custom walnut doors and more than 700 recessed ceiling lights. The approximately 2,824 square foot single-story primary closet is believed to be the largest of its kind in Texas. Amenities include a 13-seat private cinema with $500,000 in California Audio Technology speakers, a commercial-grade Brunswick bowling alley, dual kitchens, a 3,000-gallon aquarium, sauna, spa room, barbershop, 11-zone HVAC system and two elevators. An infinity-edge pool, swim-up bar, covered terraces, lake and Fred Couples Signature golf course views complete it.
