The Craver Farmstead was established circa 1790 consisting of 225 acres with a farmhouse and a barn. Today, the Craver Farmstead is both architecturally and historically significant. The farmhouse was built prior to 1790 and stands as one of the oldest and best preserved examples of Federal-style architecture in upstate New York. The Federal style evolved as the dominant classicizing architecture in North America between 1780 and1830 as the new republic of the United States sought to define itself as independent in literature, art, and architecture just as it was politically. Craver Farmstead is located on Craver Road in southern Rensselaer County, New York at the northeast corner of the town of East Greenbush, NY near the hamlet of West Sand Lake, NY. The one-mile county road bearing the site's name ("Craver Road") stretches across the original historic site to connect two more recently developed roadways. Historians agree that Craver Road was at first simply a horse trail leading to the then-new farmhouse during the mid-to-late 18th century. Soon afterward, Craver Road became a personal carriageway for the Craver Family as one may think of the modern driveway. The barn located at Craver Farmstead originally served as a private draft horse stable and carriage house for the exclusive use of the Craver family far prior to the advent of the horseless carriage. Historically, the Craver Farmstead represents the agricultural heritage of 18th and 19th century rural New York. It serves as a landmark of the region's agrarian past as well as a tangible link to the hardy folks who settled upstate New York. The Craver Farmstead is listed on the National Register of Historic Places as certified by the U.S. Department of the Interior.

North Greenbush is a town in Rensselaer County, New York, United States. North Greenbush is located in the western part of the county. The population was 13,292 at the 2020 census. The town has three main hamlets, Wynantskill in the northeastern corner, Defreestville in the southern portion of the town, and Snyder's Lake which occupies the majority of the town's eastern end. Each have strong identities and hinder efforts by the town to have a centralized identity. Also hindering a unified town image is that North Greenbush consists of parts of four different school districts, only one of which (a one-room schoolhouse) carries the town's name; two fire departments (Wynantskill and Defreestville); and three ZIP codes (City of Troy, City of Rensselaer, and Wynantskill). North Greenbush is home to the southern part of the Hudson Valley Community College (HVCC) campus, including the Joseph L. Bruno Stadium, home to the Tri-City ValleyCats minor league baseball team; the RPI Tech Park; the La Salle Institute; the New York State National Guard Armory, headquarters for the Rainbow Division; and various Rensselaer County government institutions.

The DeFreest Homestead is a historic house and barn located in the Rensselaer Technology Park in North Greenbush, New York, United States. The homestead and surrounding land are owned and managed by Rensselaer Polytechnic Institute. It was the original home of Philip DeFreest, one of the first Dutch settlers to arrive in the mid-18th century. The land includes historic buildings typical of a working Dutch farm: a farmhouse restored in 1984 to house the park's administrative offices, and a Dutch barn. The DeFreest House was built around 1765, partially constructed of European brick used as ballast in Dutch fur trading ships that sailed up the Hudson. Between 1630 and 1850, Dutch barns dominated the landscape in the Hudson Valley. They were distinguished by their H-shaped structural frame. The DeFreest barn was constructed around 1820 of thick, 50-foot beams of hemlock more than a hundred years old when hewn, and wood re-used from earlier structures on the site. The house and surrounding homestead were listed on the National Register of Historic Places in 1977. The DeFreest Homestead has been the interest of honorary trustee C. Sheldon Roberts (RPI class of 1948), and wife, Patricia. Roberts was one of the founders of Fairchild Semiconductor.A donation from the Roberts family allowed for a renovation to make the historic barn into a modern classroom for local schoolchildren.Patricia Roberts recalls, “I can remember first seeing the DeFreest House at the end of a muddy path and realizing that it must be saved in order to preserve our past but also, as importantly, to become the centerpiece of the Technology Park. We also recognized that the nearby Dutch barn could serve a similar purpose by preserving some of its history and giving it a new purpose — to become a launch pad for our children’s future.”
