Construction is progressing on 435 West 19th Street, a three-story addition and residential conversion of a former warehouse building in Chelsea, Manhattan with Rand Engineering and Architecture listed as the architect of record. The steel-framed expansion will bring the structure to eight total stories with 18 units averaging 1,400 square feet apiece. Churchill Real Estate Holdings is the owner of the site, which went through a bankruptcy auction led by Meridian Investment Sales in the early months of 2020. The original owner Six Sigma filed for bankruptcy twice with over $40 million in debt after purchasing the property for $21 million in 2014. Countywide Builders Inc. is the general contractor for the project, which is located between Ninth and Tenth Avenues.
