75 Sand Spring Rd, Harding Twp., NJ 07960-6790

Unfolding across a 15.82 acre country estate in Harding Township, New Jersey, this custom 13,093 square foot modern home, designed by Gwathmey Siegel and built in 1994, is pending sale after hitting the market for $4.3 million in September. Listing details: Designed by the renowned architectural firm of Gwathmey Siegel to meet the dynamic needs of a sports-minded owner, the architects blended a minimalist design aesthetic with expansive spaces for entertaining, private living areas within seven bedroom suites, and a focus on separate athletic facilities both inside and out. The site chosen was a 15.82-acre meadow in Morris County’s Harding Township set quietly away from the roadway. Mature tree lines outline the gently rolling land and provide a private yet open-sky setting. It includes a 12+ acre portion as farm-assessed hayfield which lessens both the maintenance and taxes.

Organized architecturally by three function-oriented wings, the heart of the three-story, 14,000+ square-foot resort-like residence begins in the first floor foyer and opens to a brilliant double-height glass rotunda that crowns the living room, dining room and sitting room on the first floor while flooding two stories of the interior with sunlight and views of the grounds. Accented by handsome built-in cabinetry, the space flows into a well-outfitted kitchen featuring double islands, a breakfast room and beyond to the pool terrace. On the opposite side of the foyer are two ensuite bedrooms joined by a gallery overlooking the lower level sports half-court. On the second floor, a sprawling primary suite offers double ensuite baths; a large walk-in closet; an exceptional dressing room with ample shelving; and a library/office. Rotunda galleries on this level overlook the living areas. A hallway with laundry and kitchenette leads to the two second floor ensuite bedrooms that share their own gallery adjoining a spacious roof deck.

The Meadow or ground floor has its own direct access from the driveway courtyard and an attached two-car garage. A staff bedroom suite and laundry room are located on this level. The foyer provides immediate access to a superb 40’x27’ game or family room with a long wet bar and counter area at one end; a fireplace and media wall in the middle; and ample display shelving at the opposite end. This room overlooks the indoor half-court on the gymnasium level below. Accessed by a staircase in the game room, this extraordinary multi-sport gym level also includes a sauna, full bath and 36’x20’ exercise room. As the lane off the main road leads toward the home’s primary entry, the driveway passes beyond a pool complex that includes a four-bay garage and generous parking. The single-level pool house contains a guest suite with bedroom, full kitchen and bath, as well as a separate unfinished poolside kitchen. An expansive bluestone terrace wraps around the deep, freeform gunite pool and links to the breakfast room and kitchen area. Accessed by a stair and downhill pathway from the main entry, the lighted regulation-sized tennis court is a focal point and has proudly produced champions. The property is pending sale and on the market for $4.3 million with Molly Tonero of Turpin Real Estate, Inc. Aerial twilight shot by Carmen Natal. Interior & exterior photography by Dave Gruol.
