Taghkanic, N.Y. | $2.9 Million

A custom-built house on 64 acres, with four bedrooms and three and a half bathrooms

The architect Toshiko Mori designed this 2005 house for a site in the Hudson Valley, where glaciers carved out hillsides and tossed around giant boulders. The wood-sided building sits between two rocky promontories and comprises a one-story pavilion with a wraparound terrace cantilevering over the side of a cliff and a parallel two-story wing.

The house is two hours north of the George Washington Bridge by way of the Taconic State Parkway. It is nine miles southeast of Hudson, N.Y., and 24 miles northeast of Rhinebeck, N.Y. It was featured in the 2011 Monacelli Press book “Nature Framed: At Home in the Landscape.”

Size: 3,670 square feet

Price per square foot: $790

Indoors: A nearly mile-long driveway takes you to the home’s frosted-glass front door next to the attached one-car garage. To the right of the entrance is a double-height great room, with a fireplace wall made of bluestone excavated on the site. Between the living and dining areas is an open kitchen with pale wood cabinets, dark stone countertops and a long island. A powder room with a pebble floor is off the great room. A glass door beyond the dining area leads to a double-height screened porch with a second bluestone fireplace.

Straight ahead of the front door is a glass-walled den connected to a guest bedroom with a window that looks out to a lichen- and moss-covered rock face. The two rooms share a full bathroom and could be set up as a suite.
