The Castle at Tarrytown commands the highest hill in southern Westchester, and overlooks the Hudson River. It was designed by Henry Kilburn to emulate a Norman Castle, and built in 1897 of gray granite quarried on site; stone walls are as thick as four feet in places.  In 1905, a two story addition was constructed with a chapel-style banquet room, bringing the total building area to 25,000 sf. During the Depression, the estate was sold and converted into offices.

​

The main objective of the project was to transform the original building into an inn with guest suites, a restaurant, and a place for parties and conferences.  We designed a new guest-room wing compatible with the original building, and restored the original Norman castle to accommodate its new functions.

​

The 11-acre site has also been transformed.  Nestled into the hillside are parking areas, trails, and a tennis court. On the south slope overlooking the Hudson River, there is a new swimming pool, spa and bath house, and a grotto-style restaurant carved into the hillside.
