A Preston Hollow estate designed as a limestone-and-copper nautilus shell is listed for $8,875,000 at 5110 Park Lane in Dallas. The property debuted at $9,999,000 in May and has been on and off the market since then.

Architect Michael Murphy designed the home across more than 17,000 square feet, including a 14,921-square-foot main house and a 2,378-square-foot attached natatorium. Faisal Halum of Compass RE Texas represents the listing.

The 1.67-acre lot sits among mature trees with a creek running through the grounds. Wedge-shaped rooms fan outward from a central elevator, with each room designed to capture a view. The arrangement creates the effect of living in a treehouse suspended in the canopy.

Lueders limestone, quarried in Texas for the project, covers both exterior and interior surfaces. The main residence has three bedrooms, buffed concrete floors, and Venetian plaster walls. A separate guest apartment adds two bedrooms. The home includes five full bathrooms and four half-baths.

The lower level contains office space, media rooms, conference areas, and a workout room. The natatorium features a lap pool with a waterfall lit by fiber optics.

A wrought-iron fence encloses the grounds. The property has parking for five vehicles and sits close to Highland Park Village and Inwood Village shops and restaurants. Dallas Love Field airport is nearby.
