Overview of 115 Eighth Avenue

115 Eighth Avenue, also known as the Chicklet Mansion, is a historic co-op building located in Park Slope, Brooklyn. Designed by architect C.H. Gilbert in 1889, this former mansion is celebrated for its Romanesque Revival architecture and has become a notable part of the neighborhood's history. The building features a variety of unique apartments, including one-bedroom units that were once part of the mansion's original dining room, showcasing exquisite details such as 12-foot ceilings, grand decorative fireplaces, and walnut wainscoting. Many apartments also offer open floor plans that enhance the flow between living spaces, making them ideal for both entertaining and everyday living.

The apartments at 115 Eighth Avenue are characterized by their charming architectural elements, including bay windows with garden views, parquet flooring, and gallery hallways perfect for displaying art. Some units, particularly those on the garden level, boast private outdoor spaces, allowing residents to enjoy the lush surroundings. Recent renovations have introduced modern amenities, such as high-end kitchen appliances and luxurious bathroom fixtures, while maintaining the building's historic charm. The co-op is pet-friendly, welcoming cats and, in some cases, dogs, and offers a generous sublet policy, making it an attractive option for potential buyers.

Located just a block from Prospect Park and within walking distance to various subway lines, 115 Eighth Avenue provides easy access to the vibrant offerings of Park Slope, including shopping, dining, and cultural events. The building's intimate size, with only 10 units, fosters a close-knit community atmosphere, making it a desirable place to call home. With its rich history and unique architectural features, owning a residence in the Chicklet Mansion is not just about living in a beautiful space, but also about being part of a storied legacy in one of Brooklyn's most sought-after neighborhoods.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
