    There's something special about a home that welcomes you before you even enter! At 18 20th Avenue, the beautiful mahogany front porch sets the tone for this exceptional Colonial, offering timeless character, modern luxury, and remarkable privacy in the beautiful Village of Sea Cliff. Originally built in 1898 and completely rebuilt in 2017 by a builder for his own residence, this thoughtfully designed home combines classic architecture with modern conveniences and quality craftsmanship. Inside, rich hardwood floors, solid wood doors, and sun-filled living spaces lead to an expansive dining area, inviting family room with acoustic pocket doors, and chef-inspired kitchen featuring quartz countertops, a 36-inch Thor gas range, wine refrigerator, and reverse osmosis water filtration. A custom mudroom adds everyday convenience. Upstairs, the primary suite offers a spa-like experience with a steam shower, radiant heated floors, marble double vanity, and 12-jet soaking tub. Three additional bedrooms and a dedicated laundry room complete the second level, while a semi-finished lower level provides additional flexible space for recreation, storage, and everyday needs, along with a second washer and dryer for added convenience. Smart-home features include Hunter Douglas motorized blinds, integrated lighting and security systems, and built-in speakers. Additional improvements include Hardie siding, energy-efficient windows, two-zone central air conditioning, and a generator hookup. Situated on just under a quarter acre, the fully fenced property is beautifully landscaped, offering exceptional privacy, multiple yard areas, a patio, and a deck ideal for entertaining. Landscape lighting and string lights create a wonderful outdoor atmosphere, while sunset views add to the setting. An oversized, recently renovated two-car garage with epoxy floors, a spacious driveway, and an EV charger provide ample parking and convenience. Just moments from Sea Cliff's waterfront, beaches, parks, restaurants, and shops, this distinctive home offers a blend of historic character, modern comfort, and private outdoor living.
