Hidden away on well over a half-acre along one of Princeton’s most coveted streets, just seconds from Riverside School and Carnegie Lake, this architecturally distinct mid-century modern offers privacy and potential. An oversized carport with a peaked roof presents a striking first impression and a sheltered welcome. The centerpiece of the interior is the dramatic living room, where one wall rises in soaring glass and the other is anchored by a double-sided fireplace shared with the den. A powder room serves guests near the nicely sized kitchen, which flows out to a stone-floor screened porch. The main-level primary wing includes a quiet study, while the upper floor hosts a second suite, two additional bedrooms and a hall bath, all washed in sunlight passing through clerestory windows. Wood floors and fresh white paint run throughout most of the interior. A shed and basement storage lend practicality. While the house is ready for thoughtful updates, the lot and location alone make this a rare opportunity. Some images are virtually staged.
