What is listed
The address is 5110 Park Lane, in Preston Hollow, Dallas. Larissa Runkle wrote it up for Realtor.com on November 5, 2026. The estate is back on the market asking $8,875,000, listed by Faisal Halum of Compass RE Texas.
Architect Michael Murphy designed the house as a limestone-and-copper nautilus. The total is more than 17,000 square feet: 14,921 square feet in the main house, plus a 2,378 square foot attached natatorium, the indoor pool building.
The plan and the lot
The rooms are wedges that fan out from a central elevator, so each room gets a view. The house sits among mature trees, and from up in that canopy it feels like a treehouse.
The lot is 1.67 acres, with rolling terrain, dense foliage and a creek. Lueders limestone, quarried in Texas, is used inside the house and on the outside.
The rooms and the natatorium
The main living quarters are on the upper level, with buffed concrete floors and Venetian plaster. The main house has three bedrooms. A separate guest apartment has two more. There are five full baths and four half baths.
The lower level holds offices, media rooms, conference areas and a workout room, and it connects to the natatorium. That pool building has a lap pool and a waterfall lit with fiber optics. Outside, a gated wrought-iron fence closes the property, with parking for five vehicles. The estate is near Highland Park Village, Inwood Village and Dallas Love Field.
The asking price since May
The house debuted in May at $9,999,000. The ask now is $8,875,000. It has been on the market and off the market since that debut. Neither figure is a closed sale.
What I would tell a Houston buyer or seller
This house is in Preston Hollow, Dallas. I work with buyers and sellers in the Houston area, including Kingwood, Lake Houston, Humble, The Woodlands, West University Place and Bellaire. I am not going to take a Dallas asking price and use it as the price for a home in those neighborhoods.
What does carry over is how a one-of-a-kind custom house finds a buyer. A plan this specific, rooms fanning from one elevator, a limestone-and-copper shell, an attached indoor pool, is not a standard floor plan. The person who wants it may not be the first one through the door, and the ask can move more than once while that buyer is found. The change from $9,999,000 in May to $8,875,000 now is one example of that. I would not treat it as a comment on the architecture. I would treat it as a reminder that a unique home still has to meet the people who will actually buy it.
If you are selling a custom home in Kingwood, around Lake Houston, in Humble, The Woodlands, West University Place or Bellaire, the design is why the right buyer will want it. Two practical things still have to be true. Price it with some realism about how many buyers want that exact house. And market it to those buyers on purpose, with the architecture explained clearly, rather than hoping a broad listing does the work. Time is part of that search. I do not have a number of days to promise, and I am not going to invent one.
