York City, Abram Hewitt, and his wife, Sarah Cooper Hewitt, and the paper reported that the Walkers left on an afternoon train up the Hudson, to be followed by a three-month tour abroad. 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. Building The Queen Anne Revival architectural style flourished in the United States during the last quarter of the 19th century. It followed the Second Empire style, which became popular beginning in the second quarter of the 19th century and reached its peak during the third quarter. The Walker House contains many elements of the Queen Anne Revival style of architecture, including an asymmetrical facade; dominant front-facing and side-facing gables; a wrap-around covered porch; spindle work; a polygonal bay; and a slate roof. It is situated on a four-acre (1.6 ha) lot. It is surrounded by tall trees; the deep ravine created by Arden Brook as well as the steep slope of Fort Hill elevate the house above the road and, together, partially obstruct the view of the house from it. A driveway curves up the slope from the east to the front facade. The building itself is a three-story frame home on a brick foundation with several nested roofs shingled in slate, together with a copper porch roof. The wraparound porch extends across the front of the house and around most of the west side and part of the east side. The steeply-pitched main roof is done in a chateau style with eyebrow vents on three sides of the house; the existing badly-deteriorated vents were replaced with custom-fitted copper vents in 2015, while the original crockets on the gable ridges were removed when the original slate roof was replaced with new slates in 2001–2002. Three large brick chimneys pierce the extensions to the north and south, and a polygonal bay extends further from the north. A veranda with turned posts and corner brackets extends around three sides of the structure. History In 1891, the New York City firm of Watson & Co. published its monumental atlas of the Hudson River in 35 separate sheets (Beers, Frederick W.: Atlas of the Hudson River Valley from New York
