Property Description

Perched on a private knoll within the prestigious Southdown enclave of Great Falls, this extraordinary custom estate commands five acres of manicured and wooded grounds backing to protected parkland with seasonal Potomac River views and direct trail access from your own backyard. A singular offering anchored by one of the oldest and largest white oak trees in all of Great Falls, a living landmark predating the Civil War. Inside, soaring ceilings, bespoke millwork, and six fireplaces set a tone that is at once grand and deeply residential. The brand-new designer kitchen flows seamlessly into the expansive family room, while the main-level primary suite provides a true sanctuary with a spa-appointed bath and an exceptional custom dressing room. The walk-out lower level is an estate unto itself, boasting a custom bar, private gym, sauna, wine cellar, and gracious guest accommodations. Beyond the walls, a private resort awaits: a heated saltwater pool and spa, a pool house, and mature, cathedral-canopied grounds that offer both beauty and absolute seclusion. Equestrian-friendly acreage, a new roof, Andersen windows, tankless water heaters, and home generator coverage complete an already impeccable package. Ultimate privacy. Irreplaceable natural beauty. And the ease of being minutes from the city — with everything already here. A resort-style living awaits you.
