Decker, Johannes, Farm
Why it's listed
Johannes Decker Farm is a Dutch farm complex of about 65 acres on the alluvial plain of the Shawangunk Kill in Ulster County, New York. The Decker family settled here around 1695. In the 1720s Johannes Decker built a one-room stone house, which became the core of the present dwelling. Additions followed before 1750, in 1784 and in 1787, producing a one-and-one-half-story T-shaped house with a flared Flemish gable roof and four brick chimneys. Southwest of the house stands a Dutch barn from about 1750 whose center aisle posts were spliced for extra height. A carriage house and an ice house, both wood frame, were added in the 18th century. The complex is valued as a complete and well-preserved example of Dutch farming life in the mid-Hudson region. The house grew with the family's means, and the later outbuildings show increasing prosperity. The property stayed within the family for more than a century.
Significance in brief: The farm is presented as an unspoiled, complete and well-preserved example of early Dutch life and building practice in the Hudson Valley. The stone house grew in stages as the family's wealth increased, and its outbuildings reflect that rising prosperity. The homestead also remained in the Decker family for more than a century.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
