A Rare 10-Acre Potomac Tuscany-Inspired Villa with Old-World Charm, Asking $9.95 Million
Set behind iron gates on nearly ten secluded acres, 13320 Signal Tree Ln in Rockville, Maryland, has re-emerged as one of the most architecturally ambitious private estates in the capital region. Priced at $9.95 million, the villa-style residence blends centuries-old European craftsmanship with modern infrastructure, offering a rare combination of privacy, provenance, and proximity to Washington, D.C.

Built in 2007, the residence spans approximately 26,716 square feet and was conceived as a long-term passion project rather than a speculative build. According to the listing, the home was designed to echo the look and feel of a historic Tuscan estate, incorporating imported materials, hand-forged elements, and architectural references drawn from medieval Europe—all while remaining minutes from major diplomatic, medical, and cultural hubs.

European Craftsmanship Rooted in Authentic Detail
The arrival experience at 13320 Signal Tree Ln immediately signals its distinction. A long driveway paved with repurposed centuries-old cobblestones, once used as ballast on transatlantic ships, leads to a grand stone façade accented by Corinthian limestone columns custom-made in Italy. Antique streetlamps line the approach, reinforcing the estate’s Old World sensibility.



“The owner was deeply committed to authenticity,” listing agent Susan Hartman of O’Conor, Mooney & Fitzgerald told Luxury Houses Magazine. “This wasn’t about copying a style—it was about studying history, sourcing original materials, and recreating a sense of place that feels timeless.”


Inside, natural light floods the soaring foyer through two-story windows, while hand-molded terra cotta floors—still bearing the imprints of artisans’ hands—anchor the interiors in history. Iron balusters forged in Italy and custom stonework throughout further elevate the home beyond conventional luxury construction.

Designed for Cultural, Diplomatic, and Private Use
With eight bedrooms and 15 bathrooms, including multiple en-suite configurations, the estate was designed to accommodate a wide range of uses. Libraries, offices, lecture spaces, and expansive gathering rooms make the property suitable not only as a private residence, but also as a venue for cultural salons, diplomatic functions, or academic retreats.

Hartman noted to Luxury Houses that the acoustics of the main hall have hosted accomplished musicians and concert-level piano performances over the years. “It’s incredibly rare for a private residence to be designed with this level of acoustic consideration,” she said. “That speaks to the intellectual ambition behind the home.”

The gourmet kitchen centers on a Lacanche range imported from France, while wellness amenities include a year-round indoor lap pool with a current system and a specialized HVAC design to control humidity—features typically found in luxury resorts rather than private homes.

Privacy and Access in the Heart of Rockville
Although the estate feels worlds away, 13320 Signal Tree Ln sits within easy reach of downtown Rockville, Bethesda, Northern Virginia, and Washington, D.C. The location places it firmly within the upper tier of Rockville Real Estate, where large-acreage properties are increasingly scarce.



“The land itself is irreplaceable,” Hartman explained in a separate conversation with Luxury Houses Magazine. “Nearly ten acres, no HOA, equestrian potential, and this level of security—so close to the capital—simply doesn’t come to market often.”


The surrounding area offers access to prestigious golf courses, major medical institutions including the NIH, upscale shopping, fine dining, and international transportation corridors, reinforcing the property’s appeal within both Rockville Real Estate and the broader Maryland Real Estate luxury landscape.

A Transaction History Reflecting Long-Term Vision
Public records show the property last traded in 2002 for $975,000, prior to the construction of the current residence. Since then, the estate has appeared intermittently on the market, with earlier listings reaching as high as $16 million before strategic repricing aligned with shifts in the ultra-luxury segment of Maryland Real Estate.

Now offered at $9.95 million, 13320 Signal Tree Ln presents a compelling value relative to its replacement cost, architectural depth, and land holdings. As Hartman summarized to Luxury Houses, “This was never built to chase trends—it was built to endure.”
