About this home

Many updates throughout this spacious 4-bedroom, 3 full bath expanded Cape, offering a versatile layout and plenty of room for today’s lifestyle. While originally built in 1937, this home is far from original, with numerous updates and improvements made over the years. Step inside to a bright living room with a vaulted ceiling, creating an open, airy feel rarely found in a traditional Cape. The updated eat-in kitchen features granite countertops and plenty of space for everyday dining. Generously sized bedrooms and three full baths provide flexibility for extended living, guests, or work-from-home needs. Additional features include central air conditioning, in-ground sprinklers, a full unfinished basement offering excellent storage and future potential, and a detached 2-car garage of approximately 400 square feet. Set on a level 140 x 89 property with plenty of room to enjoy outdoor living and entertaining. Conveniently located near major roadways, shopping, and Stony Brook University Hospital, all within the Connetquot School District. A great opportunity for buyers looking for space, flexibility, and an updated home with character!
