Description
This is a home for a lifetime. Set on a quiet stretch of Sixth Avenue between Carroll and Garfield Streets, the house is currently configured as a three-family, with a lower duplex and two floor-through apartments above. Four stories high, 19.33 feet wide and 54 feet deep, 244 Sixth Avenue offers an unusual amount of space for a Park Slope brownstone. Period detail remains throughout, adding warmth and character without overwhelming the rooms. On the parlor floor, the rooms are graciously proportioned, elegant and welcoming. At the rear, the kitchen opens directly onto a deck overlooking the garden, creating an easy connection between indoors and out. Lush greenery from neighboring gardens provides a bucolic, peaceful setting, perfect for starting your day with a cup of coffee or unwinding at the end of a busy one. Downstairs, the garden floor offers two bedrooms, a versatile middle room and a full bath. A full basement provides generous storage and utility space. Above the duplex are two floor-through apartments, offering immediate rental income and adding to the remarkable versatility of the house. Keep the existing arrangement, create two duplexes, make a triplex over a garden apartment, or ultimately convert the house to a single-family home. Reconfigure it now or later, allowing the house to adapt as life and needs change. Renovated when the current owners purchased it in the 1990s, the house has also seen more recent improvements, including a roof approximately two years old and a forced-air furnace installed five years ago. Right in the heart of Park Slope, the location is hard to beat, with the restaurants, cafés and neighborhood shops of Fifth and Seventh Avenues around the corner, and Prospect Park and transportation just a few blocks away. Its generous scale, historic character, income potential and flexibility offer something increasingly hard to find in Park Slope: a house that can change along with the people who live there. A home for a lifetime, ready for yours.
