Overview of The Twenty 1 at 117 West 21st Street

The Twenty 1 is a contemporary 12-story condominium located at 117 West 21st Street, nestled in the vibrant Chelsea/West Flatiron area. Developed by the Amirian Group and designed by Grade Architecture, this boutique building features only 9 residences, including 6 full-floor apartments, 2 duplex penthouses, and a maisonette. Completed in 2016, it has transformed the Ladies’ Mile District into a desirable residential enclave, offering a blend of modern design and urban convenience.

The building's architecture showcases a light stone frame with floor-to-ceiling windows that provide ample natural light. Notable amenities include a 24-hour doorman, a rooftop terrace, and an on-site garage, enhancing the living experience for residents. Each apartment is meticulously designed, featuring high-end finishes, spacious layouts, and gourmet kitchens equipped with top-of-the-line appliances, including Miele and Sub-Zero.

The penthouse units stand out with expansive living spaces, private terraces, and luxurious master suites. For instance, the maisonette triplex boasts a 29-foot-wide great room, a 41-foot-long terrace, and multiple recreational spaces, while the penthouse duplex offers over 4,400 square feet of living space, including a stunning master suite with a spa bath. The building's design and amenities cater to discerning buyers seeking a sophisticated urban lifestyle.

While The Twenty 1 has not been publicly associated with any celebrities, its prime location and luxurious offerings make it an attractive choice for high-profile residents. The building's proximity to Madison Square Park, shops, and restaurants further enhances its appeal, making it a noteworthy addition to New York City's residential landscape.
