About This Home

This extraordinary brick home stands on one of the Western Section’s most admired streets, just a block from the edge of town and moments from Princeton University. Every surface, inside and out, reflects a level of quality and craftsmanship rarely seen, even in this coveted neighborhood. Step inside to a sweeping staircase rising from a harlequin floor, setting the tone for interiors that are design-forward and exceptionally detailed. Arched windows, paneled walls and substantial millwork are elevated by a confident, curated palette. The home’s most memorable space - the volume-ceiling library positioned prominently off the foyer - is equal parts showpiece and sanctuary. The beamed dining room’s bespoke china cabinetry and the gourmet oak pantry in the Christopher Peacock designed kitchen are functional works of art. Further proving that practicality is paramount, the family and breakfast rooms open fluidly to the heart of the home and a first floor bedroom easily converts to an entire guest wing, if needed. Outdoors, terraced stone patios unfold alongside a water garden, leading to a pool and brick poolhouse - an architectural reflection of the home itself. French doors offer seamless access to the walk-out lower level, which does not disappoint. A game room, full kitchen, bath, gym, and additional rooms prepared to meet any need spread out from the beautiful, open staircase. Upper bedrooms offer exceptional scale and individuality, each with a private bath. The primary suite is a warm refuge with a fireplace, sitting room, two-level dressing room and a newly added infrared sauna. From custom bunks to storybook alcoves, each secondary bedroom boasts utterly enchanting features. There is truly nothing left to want at this turn-key, in-town residence.
