The Walker House is a Queen Anne Revival private residence located in Garrison, New York that is listed on the National Register of Historical Places. It was constructed in 1888 by a prominent railroad executive on his own Garrison estate as a summer cottage wedding present for one of his daughters. Garrison is located in the Hudson Valley approximately 40 miles north of New York City and sits on the eastern bank of the Hudson River, directly across from West Point. Samuel Sloan was a well-known 19th century railroad magnate, best known for his 32-year tenure as president and a director of the Delaware, Lackawanna and Western Railroad. As a prominent New York businessman, he also served as a director of a variety of other corporations, including Western Union Telegraph Company, United States Trust Company, Consolidated Gas Company, Farmers Loan and Trust Company, and the predecessor of what is today Citibank. His name is engraved in stone on the wall in the former Citibank headquarters at 55 Wall Street, and a large statue of him is located the Hoboken Terminal in Hoboken, New Jersey. Sloan and his wife, Margaret Elmendorf Sloan, purchased large tracts of land in Garrison, New York before and after the Civil War. They built their summer estate, Oulagisket (later renamed Lisburne Grange by his son), in Garrison in 1864. Sloan and his wife built the Walker House on their Garrison estate near Oulagisket in 1888. It was a wedding gift to their daughter, Elizabeth La Grange Sloan (1862 - 1960), upon the occasion of her marriage on April 27, 1887, to Joseph Walker, Jr. (1858 - 1927). Walker became a senior partner and president of the investment banking firm of Joseph Walker & Sons and member of the New York Stock Exchange. In 1982 both the Walker House and Oulagisket were added to the National Register of Historic Places as part of the Hudson Highlands Multiple Resource Area.

Oulagisket or "Lisburne Grange," also known as the Sloan Estate, is a historic estate located in Garrison, New York, in Putnam County. It consists of the main house and carriage house (c. 1864), superintendent's cottage (c. 1890), barns (1916), and carpenter's shop (c. 1900). The main house is a 2+1⁄2-story stuccoed masonry building in the Italianate style. It has a large 2-story service wing. The carriage house is a 2-story masonry building with a gable roof.The house was built by Samuel Sloan and his wife, Margaret Elmendorf Sloan, in Garrison, New York, as their summer estate, which they called Oulasgisket. Sloan, best known for his 32-year-long presidency of the Delaware, Lackawanna & Western Railroad, was a prominent 19th century railroad magnate. Now consisting of 16 acres, the original estate comprised several hundred acres, consisting of outbuildings, barns, and, ultimately, three large summer homes built as wedding presents for three of his children. The house was originally approximately 8,000 square feet and was built in the mid-nineteenth-century Gothic style then popular in the United States. His son and daughter-in-law, Katherine and Samuel Sloan, Jr., inherited the estate in 1907 and began large scale changes and modifications. The original American Indian name, Oulagiskit, was changed to Lisburne Grange, in honor of the birthplace of Samuel Sloan, Sr. in Lisburne, County Down, Ireland. The house itself was expanded by approximately 5,000 square feet and completely redesigned in the then more-popular Italianate style, largely eliminating all Gothic traces. In addition, Fletcher Steele, one America's most famous landscape architects of the first half of the 20th century, was hired to redesign and expand the existing landscaping. His work was performed in the late 1920s and resulted in a series of gardens and vistas that were widely admired as examples of his work. Following the death of Katherine Sloan in the early 1950s, the estate was ultimately sold to its first non-Sloan owners, who occupied the property until 2010, when it was sold again. Remarkably, Lisburne Grange was owned by only three families for almost 150 years. It was listed on the National Register of Historic Places in 1982.

A later occupant, architect Richard Upjohn, lived there for the last 25 years of his life. He expanded the house and redid its exterior in the Gothic Revival style that characterized much of his own work; most of these were removed in the 1920s by a later owner in order to restore the house to something close to its original appearance. In 1982 it was listed on the National Register of Historic Places. In the early 2000s it has been the subject of a dispute between the foundation which owns it and local history enthusiasts. The latter claim the head of the foundation is improperly using it as a residence and has not fully complied with Internal Revenue Service requirements that the house be open to the public as a museum. The head of the foundation denies any impropriety.
