The Gerald Luss House, a modernist home in Ossining, New York, is a single story, wood and glass residence designed to harmonize with its woodland site. It was designed by American architect, sculptor and furniture designer Gerald Luss in 1955. Featuring a prominently cantilevered design, the house was then 25-year old Luss's first residential work, and embodied his philosophies on architecture and design, which were at times overshadowed by his corporate interiors. For a time the house served as Luss' private residence. The Luss House integrated environmental harmony and design order into the home, featuring custom steel frames with glass infills and efficient air distribution systems, reflecting Luss's personal and professional and personal aesthetic. Luss, more widely known for his work on the Time & Life Building in New York City, has recently been reassessed as central to American design following the incorporation of his interiors in the set designs for the television series Mad Men. The Luss House was also featured in season two of the Apple TV+ series Severance. In 2021, an exhibition titled At The Luss House: Blum & Poe, Mendes Wood DM and Object & Thing was held inside the Luss House.

The Isaac Young House is an historic wood frame house on Pinesbridge Road in New Castle, New York, United States. It was built about 1872 in the Second Empire style. Its owner, Isaac Young, was a descendant of early settlers in the area. He chose the Second Empire style, more commonly found in cities and villages than on farms, possibly as a way of demonstrating his affluence. The present structure appears to incorporate parts of a vernacular late 18th-century farmhouse, leaving several anomalies in the current house as a result. The house's position atop a low hill would have, in its time, given it a commanding view of the region, including the Hudson River and New York City's skyline. The Isaac Young House is the only Second Empire house from that era in New Castle. There have been several renovations and alterations, including the removal of its original Italianate central tower. The current owners restored it extensively after purchasing it from the Youngs. In 2004 the house and its barn were listed on the National Register of Historic Places.

Millwood was a railroad station on the New York and Putnam Railroad in the hamlet of Millwood in New Castle, New York. It was located on Station Road just south of the southeast corner of the west end of the NY 120/133 overlap. Originally built by the New York and Putnam Railroad in 1881, this later became the Putnam Division of the New York Central Railroad. The original station house was built in 1888 but burnt to the ground soon after. The station was replaced in 1910 when the old Briarcliff Manor station was moved by flat car to the current location. The Putnam Line ended passenger service in 1958; the line was abandoned and now serves as the North County Trailway rail trail. After the line's passenger use ended, the station variously served as a real estate office and fruit and vegetable market.The station, which had fallen into a state of disrepair, was demolished on May 9, 2012 after it was determined that it would be too costly to repair. According to demolition workers, several support beams on the inside of the building had fallen down, and several others had nearly been eaten through by insects. The station was identical to the Ardsley, Yorktown Heights, Baldwin Place, and two other stations on the line.

The Carrie Chapman Catt House, also known as Juniper Ledge, is located on Ryder Road in the town of New Castle, New York, United States. It is an Arts and Crafts-style building from the early 20th century. In 2006 it was listed on the National Register of Historic Places; five years later it was designated a town landmark as well.While it is a fine example of its school of architecture, the house's primary historical value is that it was the home of suffragist Carrie Chapman Catt and her partner Mary Hay from 1919 to 1928. That period was the height of her activism; it began with the passage and ratification of the Nineteenth Amendment, which granted women the right to vote, and continued with her founding of the League of Women Voters and advocacy of women's suffrage in other countries. She found the house an ideal place to rest her "tired nerves" since the land was too steep to farm productively. However, later on she did start limited farming, including raising cattle and chickens, on the land, and made some significant modifications to the property. She also claimed to a group of guests during the early years of Prohibition that she had bought the land to prevent anyone from using its juniper berries to make gin.After nine years, she and Hay, who had never embraced the rural lifestyle, moved out. The land has been further subdivided but the house remains largely intact. It is still a private residence. Composer Carmino Ravosa, who learned of Catt's residence there while researching a musical, has worked to preserve it.
