About this home

Set above the greenery of Prospect Park, this charming Sea Cliff home offers a wonderful sense of privacy and a truly special feature: a screened-in porch that feels like sitting in a treehouse, overlooking the peaceful park below. The living room enjoys the same lovely outlook, with a wood-burning fireplace set against a stone wall adding warmth and character. Bright throughout, with natural light from multiple exposures, the home retains its classic charm, including a welcoming Dutch door. The four-bedroom, two-bath layout offers the convenience of two first-floor bedrooms, while the kitchen, remodeled in 2018, provides direct access to the backyard. A private side yard and stone-paved patio extend the living space outdoors, creating inviting spots to relax, dine or entertain. An attached garage, accessible from the basement, adds to the home's practicality. Just a few blocks from the heart of Sea Cliff Village, with its charming shops, restaurants, library and beach, this home combines distinctive character with a peaceful park-side setting. It's a special opportunity to enjoy the privacy of a home overlooking the park while remaining close to everything that makes Sea Cliff so appealing.
