Description
Apartment 1B at 321 Union Street is a modern, oversized, two-bedroom duplex with a fantastic, south-facing backyard on one of Carroll Gardens’ most coveted blocks. On a great, residential stretch of Union Street, enter through a private, gated vestibule into the large, open, living-dining space. This home features an open layout that seamlessly connects the gracious living and dining areas to both the lower level and the quiet, rear-facing bedrooms. The kitchen has room for several bar stools, a suite of stainless steel appliances, and tall cabinetry with plenty of storage. Down the hall the primary bedroom enjoys a corner exposure. There is room for a King-sized bed, a windowed en suite bathroom, and two windows looking out onto the private garden. And it is one serious garden. At 25 feet wide, this garden is far better than you find in many $5 million dollar townhouses. There is plenty of room for outdoor living and dining areas, with a raised patio surrounded by lovely landscaping and trees. The second bedroom features two large closets and can fit a queen-sized bed. There are also interior stairs leading to a versatile lower rec space, a great extra space for storage, laundry, or a gym. 321 Union is a 7-unit condo in a fantastic location. Straddling the retail corridors of Smith Street and Carroll Street, you are close to the park, schools, subways, and all the amazing shop of restaurants of Carroll Gardens and Cobble Hill.
