Overview of Opal 33 at 814 Fifth Avenue

Opal 33 is an 11-unit boutique condominium located at 814 Fifth Avenue in Brooklyn's South Slope-Greenwood Heights neighborhood. The low rise building offers a mix of studios, one bedroom, and two bedroom residences ranging from 539 to over 900 square feet, with several units featuring private outdoor terraces ranging from 93 to 217 square feet. A standout feature is Residence 1A, a duplex maisonette studio that includes a generous 522 square foot private cellar space that can serve as storage, a home office, creative studio, or personal gym.

All residences share consistent design elements including oversized windows that flood the spaces with natural light, open concept great rooms, and sleek modern kitchens equipped with integrated appliances such as full size refrigerators, dishwashers, and microwaves. The bedrooms are designed to accommodate queen sized beds (with the larger units featuring king sized primary suites), and all units include spa inspired bathrooms and in-unit washer/dryers. Notable architectural details include wide plank flooring, distinctive angular elements, and generous closet space throughout.

Building amenities focus on practical luxury with an on-site parking garage, private storage solutions, a fitness center, and a rooftop deck offering panoramic views. The parking garage is particularly noteworthy in a Brooklyn location where street parking can be challenging. The rooftop terrace serves as a shared outdoor amenity complementing the private terraces found in select units.

The building sits in the trendsetting Greenwood Heights area, positioned between the energy of South Slope, the innovation hub of Industry City, and the evolving Gowanus neighborhood. Residents have easy access to Greenwood Cemetery, the dining scene along 4th Avenue, and the shopping and cultural offerings of nearby Industry City, making it well connected to Brooklyn's diverse landscape of dining, nightlife, and transportation options.
