Set just across from scenic Carnegie Lake in Princeton's coveted Riverside neighborhood, this thoughtfully rebuilt 2007 colonial split blends architectural character (Peter Morgan, architect) with an uplifting, light-filled design. Inside, soaring vaulted and beamed ceilings define the home's inviting main living spaces. The open living and dining area flows effortlessly into the expansive eat-in kitchen which echoes the same airy volume--complete with a large center island, a Wolf six-burner range and commercial grade appliances enhanced by granite counters, a charming breakfast nook with a window seat. The entire kitchen is surrounded by walls of glass-front and open shelving cabinetry that adds both style and function for storage and collection displays. The generously sized sunken family room creates a natural gathering space, anchored by two sets of French doors that open to the patio for seamless indoor-outdoor living. An interior French door reveals a stunning 2015 addition consisting of a window-wrapped study crowned by a cupola--an inspiring retreat that easily doubles as a private in-law suite, with an adjacent full bath and a bedroom tucked just beyond for privacy, featuring skylights and vaulted ceilings. The home's signature design element--a dramatic, open staircase--serves as both a visual and functional centerpiece, rising through the heart of the home and culminating in skylights above. This architectural design was intentional to allow connections to each level while enhancing natural light and creating a sense of openness rarely found in multi-level living. The varied levels themselves offer a unique advantage for distinct spaces that provide privacy, flexibility, and separation without sacrificing flow. Additional highlights include a versatile fifth bedroom on the main level with a full bath, a well-appointed mudroom with built-ins, and access to an unfinished basement. Upstairs, a cozy library with custom shelving leads to the serene primary suite with vaulted ceilings, a spa-like bath featuring a oversized air jet-tub with Chromatherapy and a heated back rest, an oversize shower and private water closet. The uppermost level offers two additional bedrooms which share a full bath and laundry room at the end of the hall. With a two-car attached garage, a privately fenced backyard and patio, and a location just moments from Riverside Elementary School and Princeton University, this home offers a rare combination of character, light, and livability in one of the area's most desirable settings.
