SPECTACULAR LIGHT. DISTINCTIVE DESIGN. EXTENSIVELY UPDATED. Set on NEARLY 2 ACRES in one of SAUCON VALLEY’s most desirable neighborhoods, this custom estate pairs dramatic architecture with substantial recent improvements. A striking arched glass entrance frames mahogany double doors, with new walkways and a renovated front patio creating a welcoming arrival. Inside, a soaring marble foyer, GRAND DOUBLE STAIRCASE, and stunning two-story windows make an unforgettable first impression. Floor-to-ceiling glass and a fireplace anchor the living room, while the richly appointed study—with its mahogany coffered ceiling and fireplace—offers an inviting retreat. A formal dining room sets the stage for special occasions, and a cozy sitting area beside the study is perfect for unwinding. The kitchen’s charm lies in the details: a cozy BRICK FIREPLACE, built-in reading nooks, and five sets of glass French doors connecting the kitchen and adjoining gathering spaces to the outdoors. An island, double ovens, and Sub-Zero refrigerator complement a prep area and coffee bar tucked beside the rear spiral staircase. Outside, beautiful patios, an OUTDOOR KITCHEN, and a DOUBLE-SIDED FIREPLACE set the scene for memorable gatherings or quiet evenings, with updated landscape lighting adding ambiance after sunset. Upstairs, enjoy THREE EN SUITE BEDROOMS with the highlight being a spacious primary retreat with a stone fireplace, custom built-ins, two walk-in closets, a private balcony, and a bath with a jetted tub and steam shower. An adjoining sitting room offers flexibility as a nursery or second office. The second level laundry adds convenience, while the finished lower level features a wine cellar, wet bar, game room, and full bath. Extensive improvements include a NEW ROOF and six-inch gutters, NEW HVAC, refinished first-floor oak hardwoods and new oak flooring upstairs, custom closets, automated blinds, an enhanced security system, numerous new appliances, a new deck, and updated interior and exterior lighting. Distinctive CRAFTSMANSHIP, SUBSTANTIAL UPDATES, and a COVETED SAUCON VALLEY SETTING—1751 Deer Run Road is ready for its next chapter.

The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
