Monthly Estimate* How much can I afford?

This beautifully updated Sea Cliff bungalow offers a charming blend of character, comfort and modern convenience. Sunlight pours through oversized windows and brand-new skylights (installed late 2025, when the roof was also redone), highlighting the warm wood floors throughout. The main level features a first-floor bedroom, home office and dining area, a den, and an inviting open kitchen. A unique spiral staircase leads to an open sleeping loft with its own skylight and windows. Two generous closets upstairs. The downstairs also features a bedroom closet and an office closet. Outside, a private garden enclosed by bamboo fencing creates a peaceful retreat, while a bluestone patio is perfect for outdoor dining and entertaining. Additional conveniences include two-car parking and an electric vehicle charger. While this one-of-a-kind bungalow is on a quiet residential street, it's also in the very heart of Sea Cliff, offering easy access to the village's restaurants, coffee shops, arts and music scene, and Sea Cliff's beautiful clifftop park, which offers views across the Long Island Sound. Additionally, Sea Cliff's LIRR station is less than a mile away.
