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.

Demolition Permits have been filed for 517, 519, and 523 West 29 Street, in West Chelsea, Manhattan. The site is just blocks away from Hudson Yards. This comes over a year after reports broke that developer Six Sigma paid a pricey $800 per buildable foot for 4,900 square feet of air rights to add to the project. The $3.92 million purchase allows the developer to add another floor to the top of the structure, which can be expected to sell for quite a sum. Six Sigma purchased the actual property for $54.75 million.

Developer Six Sigma has acquired, for $3.92 million, 4,900 square feet of High Line Transfer Corridor air rights for its planned 10-story, 61-unit condominium project at 517 West 29th Street, in West Chelsea. The development rights will be used to build larger and taller, the New York Post reported. Not including the recently-acquired air rights, the 9,875-square-foot site can accommodate up to 74,260 square feet of residential space, plus an additional 24,490 square feet of commercial or community space. Plans have not been filed with the Buildings Department, although demolition permits were filed in August for the existing six-story warehouse. A construction timeline has not been disclosed.

Back in October of 2015, Six Sigma was in contract to buy the six-story, 55,000-square-foot commercial building at 517-523 West 29th Street, in West Chelsea, for $54 million. The developer has since closed on the purchase and has now filed exploratory applications with the Attorney General’s office to gauge the demand for a potential condominium project, The Real Deal reports. Although details are sparse, the project would include 61 condominium units and ground-floor retail space. It’s not clear if the existing building would be demolished for a new one, although the site can accommodate up to 74,000 square feet of development potential (which means it currently has 19,000 square feet of air rights). Nothing has been filed yet with the Department of Buildings.
