Overview of The Slope on Fifth at 445 5th Avenue

The Slope on Fifth stands as a six story boutique condominium at 445 5th Avenue, strategically positioned just outside the Park Slope Historic District where new developments can rise as of right. Developed by RJ Capital Holdings, this 30 unit building represents a modern addition to the neighborhood while the protected streets lining Prospect Park West maintain their century old character.

The building's residential offerings include a mix of layouts crowned by five penthouses featuring private outdoor space. Many units throughout the building benefit from private terraces or balconies, providing residents with coveted outdoor access. The compact scale of just 30 units ensures an intimate, boutique living experience that distinguishes it from larger developments in the area.

Interiors showcase Scandinavian influenced design with high ceilings and European oak PID hardwood floors creating a sophisticated foundation. Each unit includes in-unit Bosch washer and dryers for convenience. Kitchens are outfitted with custom Lineadecor wood cabinetry, white stone countertops, and Bosch appliances, maintaining a cohesive design aesthetic throughout the building.

Residents have access to a comprehensive amenity package including a fitness center, business center, game room, and lounge for various lifestyle needs. The building also provides practical amenities such as a package room and bike storage, while the roof deck with grill offers outdoor entertaining space. Private storage and parking are available for an additional fee, addressing the storage challenges common in Brooklyn living.

The location provides easy access to Prospect Park's dog beach and the dining scenes along 5th Avenue and 7th Avenue, including proximity to Nitehawk Cinema and the Gowanus Whole Foods. Transportation connectivity is strong with the 4th Avenue 9th Street F/G trains and Prospect Avenue D/N/R/W trains providing multiple subway options for commuting throughout the city.
