Brown Harris Stevens Lists Former Historic Stribling & Associates Office in Chelsea

In one of New York City’s most storied real estate neighborhoods, a piece of real estate history has just hit the market The property at the heart of this buzz isn’t just another luxury townhouse; it’s the former home of what is reputed to be America’s longest-running real estate office, now completely reimagined and offered as a private residence for the first time ever.

Originally occupied in 1819 by James N. Wells & Sons, this Chelsea townhouse at 340 West 23rd Street has held the distinction of being the longest-continuously operating real estate office in the United States. Over the centuries, it served generations of brokers and clients — a true living piece of the city’s commercial past. Most recently, it served as the Chelsea office of Stribling & Associates, which was acquired by Compass In 2019. At this point,  the property quietly left its office roots behind.

What was once boardrooms and broker desks has been meticulously transformed into a sprawling 9,422-square-foot luxury home –  a project three years in the making. The result blends the historical charm of a landmark building with contemporary design touches and high-end finishes.

Step inside and you’ll find:

• A grand glass entryway with soaring 20-foot ceilings
• Oversized windows that flood the interior with light
• A sculptural central staircase and striking designer lighting
• Six bedrooms and multiple living spaces designed for both comfort and entertaining
• A standout glass atrium and dual-level rooftop terrace offering panoramic Manhattan skyline views

Luxurious details, including marble baths and custom millwork, give the residence an elegant yet livable feel, making it a standout example of how commercial architecture can be re-envisioned as a contemporary urban dream home.

Listed by David Kornmeier for $17.7 million, this property represents a rare opportunity to own both a piece of New York City history and a stunning, one-of-a-kind residence in Chelsea.
