Stunning Ultra-Modern Estate by Gary Gallagher Hits the Market in New York for $10.75M
Set on five acres of manicured grounds, 31 Chestnut Hill Drive emerges as one of the most compelling offerings in Upper Brookville Real Estate, now listed at $10.75 million after an extensive multi-year transformation. Known as Maison Blanche, the estate blends architectural pedigree with cutting-edge design, positioning itself at the forefront of New York Real Estate.
Originally built in 1989, the residence has undergone a dramatic reinvention between 2023 and 2026, elevating it into a fully modernized sanctuary tailored for today’s high-net-worth buyer. With over 10,000 square feet of interior space, the home delivers both scale and sophistication in equal measure.
A Legacy Property Reimagined for Contemporary Living
The evolution of 31 Chestnut Hill Drive reflects a broader shift within Upper Brookville Real Estate, where legacy estates are increasingly being reinterpreted through a modern lens. Designed initially by architect Gary Gallagher and later reimagined by award-winning FAIA architect Stuart Narofsky, the property now presents a bold architectural identity defined by clean lines, expansive glass, and refined materials.
“The goal was to respect the original structure while bringing it fully into the present,” said listing agent Ephraim J. Simon of Serhant East End in a conversation with Luxury Houses Magazine. “Today’s buyers in New York Real Estate expect something turnkey, something that feels both architectural and livable.”
Inside, the residence unfolds with a sense of openness and light. Floating staircases, floor-to-ceiling windows, and a palette of porcelain and white oak create a seamless flow between spaces. Every detail—from the custom doors to the curated finishes—has been carefully considered to reflect a contemporary lifestyle.

Designed for Wellness, Privacy, and Entertaining
At its core, 31 Chestnut Hill Drive is designed as a private retreat. The six-bedroom layout includes a primary suite on the main level, offering both convenience and seclusion. Upstairs, additional bedrooms are complemented by a dedicated wellness zone, including a private gym and Finnish sauna.
The lower level transforms into an immersive entertainment environment, complete with a Dolby Atmos theater, wine tasting room, and a spa-like area designed for yoga and massage. These features align with evolving expectations in New York Real Estate, where homes are increasingly expected to function as self-contained lifestyle hubs.
“This property speaks to how people live today,” Simon told Luxury Houses. “It’s not just about square footage—it’s about experience, wellness, and the ability to entertain effortlessly.”

Expansive Grounds in a Prestigious Enclave
Beyond its interiors, 31 Chestnut Hill Drive offers an equally impressive outdoor setting. The estate’s five-acre parcel, positioned at the end of a quiet cul-de-sac, provides a rare level of privacy within Upper Brookville Real Estate. A heated saltwater pool and spa anchor the outdoor experience, surrounded by a porcelain patio and minimalist glass railings that preserve uninterrupted views of the landscape.
The setting reinforces the enduring appeal of the Gold Coast lifestyle, where expansive properties, tree-lined streets, and proximity to Manhattan continue to attract discerning buyers. In this context, the estate stands out not only for its scale but for its modern interpretation of luxury.

A Remarkable Price Journey Reflecting Transformation
The pricing trajectory of 31 Chestnut Hill Drive underscores the scale of its transformation. The property last traded in 2023 for $2.5 million, before undergoing a comprehensive redevelopment that has now brought it back to market at $10.75 million. Earlier listings dating back to 2012 show asking prices in the $4 million to $5 million range, highlighting how significantly the asset has evolved.
“In Upper Brookville Real Estate, it’s rare to see this level of value creation in such a short period,” Simon noted to Luxury Houses Magazine. “The investment here wasn’t cosmetic—it was a complete rethinking of what the home could be.”
This dramatic repositioning mirrors a wider trend across New York Real Estate, where buyers are willing to pay a premium for properties that require no additional work and deliver immediate lifestyle benefits.
A Modern Benchmark for the North Shore Market
As demand continues to shift toward fully realized, design-forward homes, 31 Chestnut Hill Drive represents a new benchmark within both Upper Brookville Real Estate and New York Real Estate. Its combination of architectural pedigree, advanced technology, and resort-style amenities places it in a category of its own.
“The owner envisioned something timeless yet forward-thinking,” Simon said in a final remark to Luxury Houses. “What you see today is a home that truly reflects the future of luxury living on the North Shore.”
The listing is currently featured on Zillow, offering broad exposure to global buyers, while additional details can be accessed through the brokerage Serhant, known for representing high-end properties across competitive markets.
