Welcome to 20 Helene Court — a beautifully updated, legal 2-family detached home tucked away on a quiet cul-de-sac in the highly desirable Prince's Bay section of Staten Island's South Shore. Set on an oversized 40×178 lot (7,120 sq ft), this property offers approximately 2,322 sq ft of total living space and exceptional flexibility for end-users, investors, or multi-generational living. The main residence features 3 bedrooms and 2.5 bathrooms with refinished hardwood floors, recessed lighting, and ceiling fans throughout the bedrooms and kitchen. The renovated eat-in kitchen offers granite countertops, updated cabinetry, tile backsplash, stainless steel appliances, new flooring, and modern lighting. A spacious living room opens to a newly built front balcony deck, perfect for outdoor enjoyment. The primary bedroom includes a walk-in closet and a private updated full bath. Additional highlights include beautifully renovated bathrooms, a large enclosed sunroom overlooking the backyard, and an attic with pull-down stairs providing excellent storage. The second unit is a fully renovated 1-bedroom, 1-bath apartment with a private entrance — ideal for rental income, extended family, guest suite, or home office use. The expansive backyard offers tremendous potential rarely found with today's new construction. Backyard photos are virtually staged to illustrate possibilities. The existing pool requires TLC, presenting an opportunity for the next owner to restore, redesign, or reimagine the outdoor space to fit their vision. Conveniently located near parks, schools, shopping, dining, and transportation, this versatile property delivers space, flexibility, and long-term value in one of Staten Island's most sought-after South Shore neighborhoods.
