Nestled on four acres in the luscious Hill Country, 8004 Two Coves Drive is a convenient short drive from Lake Travis, Emma Long Park, Downtown Austin and the Domain. Of course, it would be faster to take your helicopter.

Listed for a cool $5.2 million, the 5,597-square foot luxurious six-bedroom, six-bathroom home in Northwest Austin comes with a gym, guesthouse, gazebo and landing pad. You know, for your helicopter?

However, the aircraft accessories aren't all that make this sprawling house special.

Upon coming in through the steel gates, note that security is the name of the game with 18-foot-high, four-foot-thick concrete walls. The house also comes complete with an extensive security system and private water well with a filtration system.

Once inside, you will marvel at the meticulously manicured courtyard that leaves plenty of space between the gazebo, guesthouse and main house.

The pueblo-esque house overlooks coveted greenery and views, featuring a pyramid-inspired sitting area to look upon the natural limestone pool and spa or enjoy the sounds of the nearby bird sanctuary, which will remain undeveloped, securing the home's solitude.

Inside, the home has clean lines, lots of natural lighting, travertine flooring and custom metal and stonework. Although the house was built in 2001, it has been outfitted with smart home technology.

What house would be complete without a secret, cave-live dining room? The fortress features a hidden room with walls of quarried stone, perfect for your next Game of Thrones LARP.

Buyers of the house have the option to buy the Pietro Constantini custom artwork and furniture pictured inside or even expand the home, which has room for a new 30,000-foot structure.

The fortress is listed by Douglas Elliman—the broker behind Eklund | Gomes team from Bravo's "Million Dollar Listing"—Texas' Senior Vice President Matthew Ditlow.
