The 22,000-square-foot Houston mansion, known as The Lodge at Hunter's Creek, was completed in 2005 after several years of construction.

"If you combine the setting and the structure, you have something very unique, and it can't be replicated," said Billy Dolan, listing agent for Dave Perry-Miller - Preston Center.

"It's almost impossible to find a nine-acre residential lot in Houston," Dolan explained." It's surrounded by an estuary, so it has water views and landscaping. It has a view of the downtown skyline and is only minutes away from downtown Houston. When you're there, you feel like you're in the country, but in a major residential area."

The main house, located behind a guarded gate, has six bedrooms and eight bathrooms. Everything inside and out is of the highest quality, Dolan says.

"The house is magnificent," he says, praising it." It's not something you can explain unless you walk in and feel the quality of it. Throughout the house, you see mahogany everywhere. The amount of money that went into building this house is unbelievable."

He says he knows how much it cost, but won't elaborate.

The limestone used for the steel exterior walls and interior floors came from the same Indiana quarry that has supplied stone for the Pentagon and other high-profile projects.

A 3,500-square-foot, two-bedroom guest cottage with its own pool is located on a tree-lined gravel road near the main house. It was on the property when the owner, Colleen Romanov, bought it. Romanov's former husband is technology entrepreneur Michael Holthouse.

"It started out as a hunting lodge," Dolan said." My client rebuilt it, renovated it and lived in it while she built the main house. When you look out your bedroom window, you're surrounded by a flowing estuary feature. You can hear a pin drop. It's like being in nature, very peaceful. It's hard to get any guests to leave."

Actress Shirley MacLaine reportedly lived in the building while filming parts of the 1983 movie "Terms of Endearment.

The property also has five show car garages, two swimming pools, a glass elevator, an outdoor kitchen, and plenty of space for entertaining.

After another agreement expired, the price of the property actually increased by $5 million when it officially came on the market. The increase vaulted the home's price past a $60 million property in Dallas that just last month earned the title of the state's most expensive home.

"The owners of the property didn't fully agree with their offer at the time," Dolan explained." She did a lot of research and inspection and was very impressed with its value."

The one-of-a-kind home was difficult to price because nothing was exactly like it.

"You really have to evaluate it with a replication approach and a cost approach," Dolan notes." The truth of the matter is you probably couldn't [build] it again. It's so special. If you look at the cost per acre, the cost of site development, the cost of construction and pull all of that together, we came up with a value. We're looking for buyers who know what's out there and can understand and appreciate it."
