General Stores and Mold Loft Building-Harriman Yard of the Merchant Shipbuilding Corporation
Also known as: Manhattan Soap Company Warehouse
Why it's listed
Built in 1917 as a three-story reinforced concrete warehouse on Radcliffe Street in Bristol Borough, the General Stores and Mold Loft Building was among the first structures completed at the Harriman Yard of the Merchant Shipbuilding Corporation. The yard was one of three prefabricated shipbuilding facilities the Emergency Fleet Corporation established during World War I to produce transport ships. Its mold loft, where full-size hull templates were laid out, was central to that prefabrication process. Around 1925 the Manhattan Soap Company acquired the building and used it as a warehouse until 1950 and beyond. Most other yard buildings were later demolished, leaving this building as the last major remnant of the shipyard. Its open floor plans, round concrete columns, and exposed framework reflect early twentieth century warehouse construction. The building was vacated in 2000 when the soap plant closed.
Significance in brief: The nomination argues the building is the last major surviving structure of Harriman Yard, one of three prefabricated World War I shipbuilding yards, and that it was one of the first built there because its mold loft function was integral to ship construction. It is also presented as a representative early twentieth century reinforced concrete warehouse retaining its character-defining features.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
