Why it's listed

Beside the Hudson River in Ossining, this group of brick, wood and corrugated-iron buildings grew from the pill works Dr. Benjamin Brandreth established in 1836. Brandreth, an English-born patent medicine maker who relied on testimonial advertising, chose the village for its water and river transport. The oldest survivor is a Greek Revival storage building of 1836, possibly designed by New York architect Calvin Pollard. After an 1872 fire destroyed the original factory, most of the remaining buildings were added in the 1870s and 1880s, with pill making and plaster making kept in separate sections to limit fire risk. The largest is a red brick Italianate factory with a mansard roof, built on the site of earlier mills. Other structures include an office, a blacksmith shop, a coal shed, a Gothic Revival box-making building and an early corrugated iron warehouse. Together they record the growth of one of Westchester County's earliest industries and its role in Ossining's development.

Significance in brief: The complex predates the 1848 railroad and was a major factor in Ossining's nineteenth-century industrial growth, as one of the earliest manufacturing complexes in Westchester County. Its buildings show a cross-section of regional architectural styles applied to industrial use. It is also closely tied to Dr. Benjamin Brandreth, an important figure in patent medicines, American advertising and the village's development.

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.
