21 West 20th Street in Manhattan, NYC, is home to the ultra-luxury residential development known as 21W20, completed in 2016. The building comprises thirteen full-floor residences located in the heart of the Flatiron District. Designed with a modern aesthetic by MR Architecture + Décor, the architecture emphasizes space, proportion, and light, with a façade that features a sophisticated blend of blackened stainless steel, glass, and stone.

The building rises to the tenth floor in a narrower form and then expands to its full width of 100 feet, revealing three expansive penthouse homes atop a neighboring, restored, landmark-protected structure. Each penthouse includes private terraces and floor-to-ceiling southern exposures, featuring folding terrace doors that promote seamless indoor-outdoor living. The design of the residences is subtle and refined, reflecting a dedication to enhancing the vibrant lifestyles of their inhabitants.

The development stands as a modern addition to the historic Flatiron area, blending contemporary luxury with the character of the neighborhood. The residences are distinguished by their meticulous attention to detail and integration of high-end finishes and features, making 21 West 20th Street a notable address in Manhattan's real estate landscape.

Prior to this modern development, the area around West 20th Street included historic structures such as the Federal-style house at 210 West 20th Street, dating back to the 1830s. This modest three-story brick home over a brownstone English basement reflected the working-class character of the neighborhood before its transformation. Though many similar early 19th-century buildings were replaced as the city developed, 210 West 20th Street survived with alterations converting it into multi-family residences by the 1930s, and was sympathetically restored in the early 2000s to maintain its historic Federal-style features.

Thus, 19-21 West 20th Street represents a blend of New York City's architectural evolution—from modest early townhouses serving working families to ultra-luxury modern condominiums embodying contemporary urban living.

We love a challenge!

Optimal Spaces can help you turn critical and complex real estate issues into opportunities for growth and or cost reduction. We offer the experience, know-how, and the strategic planning that helps lead to better decisions. Virtually everything you need to enhance the value of your business (for profit and not for profit) , you will find at Optimal Spaces.

About Optimal Spaces
Optimal Spaces are Tenant Brokers, only representing commercial tenants, not owners or landlords. By contrast, managing agents and most commercial brokers are "landlord agents" representing the interest of owners. Their goal is to market and lease their clients' properties with the best possible terms for the owners. Thus, they will neither show you as broad a selection nor push to get the best price, since their loyalty is to the Landlord. An Optimal Spaces agent will show you a broader range of properties and offer you a broader range of important services than a managing agent or commercial broker will. We will provide you with a market survey, floor plans, pricing expectations , and access to our rolodex: Optimal Spaces walks you through the process from start to finish. Upon entering your new space, it will look the way you want, all at the price you agreed to spend. In addition to negotiating the best price, we will reveal and abate many "hidden costs" to you. We will show you all the relevant available spaces and safeguard your interests throughout the process. Because of tour costs to provide these services, we ask in exchange that clients sign an Exclusive Brokerage Agreement. This allows us to plan appropriately for assisting you with every step of the process.
