Description

Set on a lush .93-acre homesite, this extraordinary 8,500+ sq. ft. Toll Brothers Henley Federal residence is a masterclass in scale, elegance, and modern refinement. A stately brick façade and beveled glass entry open to a breathtaking two-story foyer, where twin sweeping staircases establish a sense of timeless grandeur.
Every space has been thoughtfully curated—from the formal entertaining rooms with intricate millwork to the sunlit atrium retreat. At the heart of the home, the designer kitchen redefines luxury living, blending quartz surfaces, custom soft-close cabinetry, and a statement island built for gathering. The adjoining sunroom and expansive deck create a seamless indoor-outdoor experience.
The soaring two-story great room, anchored by a dramatic brick fireplace, offers both comfort and architectural impact, while a private library provides a quiet space for work or reflection.
Upstairs, the primary suite is a sanctuary unto itself—complete with a sitting room, an extraordinary 26-foot dressing room, and a spa-caliber bath crafted in porcelain and quartz. Each additional bedroom is a private suite, offering elevated comfort for family and guests alike.
The lower-level transforms into a full-scale entertainment destination, with a rec room, brick, gas fireplace, home theater, bar, finished storage/gym space, 2nd office, and 5th bedroom, full bath and additional guest accommodations.
Outdoors, the estate continues to impress with a fully fenced yard, mature fruit trees, professional landscaping, a 7-zone irrigation system and multiple spaces for gathering and relaxation.
With a 3-car garage, EV charging, smart home features, and a premier location near top-tier shopping, dining, and commuter routes, this home delivers an exceptional lifestyle at every turn.
