Behind the gates of Walnut Brook Estates, this 8,432-square-foot custom estate delivers a rare combination of scale, craftsmanship, and privacy in the heart of Rochester Hills, within the acclaimed Avondale School District. Designed by ADZ Architects, the home unfolds across multiple levels with soaring 27-foot ceilings in the formal living room and a grand foyer that sets an unmistakably elegant tone the moment you step inside. Natural light pours through the open layout, where the gourmet kitchen anchors daily living and flows effortlessly into the breakfast nook and a fireplace-warmed great room built for both quiet mornings and lively gatherings. A formal dining room off the foyer accommodates large family celebrations with ease, while a wet bar and library with a private half bath complete a first floor designed for both entertaining and retreat. Finishes throughout reflect uncompromising quality: marble and granite surfaces, eight-foot mahogany doors, and thick crown molding lend a sense of permanence and polish rarely found at this level. With 8 bedrooms and 10 total baths, the home offers exceptional flexibility for multigenerational living or a growing household. First-and 2nd-floor primary suites each feature spa-inspired baths and generous walk-in closets, while six additional bedrooms provide their own well-appointed baths and closet space, ensuring privacy for everyone under one roof. The finished walkout lower level adds roughly 4,000 square feet of true living space, not just storage, complete with a full second kitchen, bar, recreation room, and a second fireplace-anchored family room, an entertainer's dream that opens directly to the backyard. A spa, wet and dry sauna, and dedicated exercise room round out the level, while a three-car side-entry garage provides ample storage and access. Outside, a private backyard oasis awaits with an in-ground pool, spa, patio, and deck, ideal for both everyday relaxation and destination-worthy entertaining.
