337 West 20th Street was built as a foundry in 1850 and later used by Samuel Bath Thomas to bake his English muffins. In 1982, it was converted to The Muffin House, an 11-unit cooperative in a prime Chelsea location.
The Muffin House is a four story pre-war co-op at 337 West 20th Street, created in 1982 from an 1850 foundry. Samuel Bath Thomas later converted the foundry ovens, whose arched brick structures remain beneath the courtyard, for his English muffin bakery. The building has 11 residences and includes both a front structure and a rear carriage house.
A cobbled common courtyard connects the two parts of the property, while the rear carriage house contains a distinctive penthouse arranged on the top floor with access to a private roof garden. The apartments commonly retain pre-war details such as high ceilings, exposed brick, hardwood floors, skylights, wood burning fireplaces, and southern exposures; private roof rights and in-unit washers and dryers also recur among the residences.
The building is a walk up with an intercom and video security. Its mid-block position is directly across from St. Peter's Episcopal Church and the Atlantic Theater, on a tree-lined block in West Chelsea. The High Line, Chelsea Piers, Chelsea Market, art galleries, restaurants, cafes, and shops are all close by.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
