676 Union Street: A Rare Park Slope Sanctuary
Welcome to 676 Union Street, a rare Park Slope sanctuary. This distinctive 25-foot-wide loft building is a true legacy, maintained for 40 years and now offered to those who seek the extraordinary. Encompassing over 6,500 square feet, this residence seamlessly blends classic Brooklyn grandeur with the cosmopolitan allure of a Soho atelier.
