When Charlotte Bronson Hunnewell Martin built the great stone house known as Cornwall Castle as a country retreat in the 1920s, she added a pottery to the estate and hired an Italian potter named Vincenzo Rondinone to run it. The building, which has a dozen gables and 18-inch-thick fieldstone walls, was eventually converted into a residence. In the late 1990s, the potter’s son, Nicholas Rondinone, an architect, bought it, updated it and built additions. The current owners bought the property in 2000 and installed a new kitchen. They also added a detached two-car garage.

The house is in rural Litchfield County, about 100 miles northeast of New York City and 150 miles southwest of Boston. It is about three miles southwest of the Cornwall village center and Mohawk Mountain ski area and eight miles southeast of Housatonic Meadows State Park.

Indoors: The main entrance opens into the original kitchen — a rebuilt foyer with radiant-heated limestone floors, off of which the owners added a half bathroom with a stone basin. A hallway leads to a great room with oak floors, a beamed ceiling and huge arched windows set into exposed-stone walls. The original potter’s wheel sits next to a stone corner fireplace.

A doorway with a diamond-muntined transom and sidelights leads into the eat-in kitchen, a former clay-drying area that the current owners enclosed and to which they added aluminum-framed Marvin windows. The floor is Israeli limestone, and the custom cabinets have soapstone countertops. The appliances include a six-burner Viking stove with double ovens and two Fisher & Paykel dishwasher drawers that can be loaded and unloaded without bending over.

The house has many unique decorative flourishes. Incised over the original entrance, which opens to the stair hall, is a French inscription that is a 16th-century Italian potter’s prayer. A door leading from the great room to this area is ornamented with a grid of wood squares. And the casement windows in the library are topped with carved panels acquired from a demolished Manhattan theater.

The primary bedroom is on the main level. It has a California closet, French doors leading to an outdoor patio and an en suite bathroom with a jetted tub and a wall of storage. A second bedroom on this level is used as an office and has a full view of the waterfall. The two upstairs bedrooms include one with a Juliet balcony and a private bathroom.

Outdoor space: Statues of Knights Templar decorate the gates to the property. A large stone patio wraps around the building, from the entrance to the kitchen. The garage has extensive room for storage.

Taxes: $9,123 (based on a tax assessment of $546,300)

Known as Greylogs Estate, this home is believed to have been modeled on the historic Grove Park Inn in Asheville, N.C., and has been owned by one family since the early 1960s. It is four miles east of downtown Spartanburg, a city of about 38,000 in northwestern South Carolina, and is extraordinary for the amount of land that surrounds it. (Buyers can opt to purchase the house with almost 20 acres, for $2.487 million.)

The property is centered between the Edwin M. Griffin Nature Preserve and the Country Club of Spartanburg, both within a mile. Asheville is about 70 miles northwest; Charlotte, N.C., is about 70 miles northeast; and Charleston, S.C., is about 200 miles southeast.

Size: 5,199 square feet

Price per square foot: $260

Indoors: Much of the living space is on the main level and centers on a living room with a 10-foot ceiling, paneled walls and a massive stone fireplace reminiscent of the one at the Grove Park Inn. On either side are wood doors with strap hinges; they lead to a large screened porch with a plank ceiling and log beams. The formal dining room overlooks the front lawn through a bay window flanked by built-in china cupboards.

The eat-in kitchen is wrapped in wood cabinets with linoleum countertops and has a blue-and-white tile backsplash, open ceiling beams and lighting recessed behind cornices. A laundry room is next to it.

All five bedrooms are on the main level, three on one side and two on the other. The master has a working stone fireplace with gas logs and a bathroom with a marble-topped double vanity and French doors opening to a balcony overlooking the lawn. The master suite also includes a paneled study with a wall of built-ins and three closets.

A staircase descending from the brick-floored foyer leads to the lower level, with two large rooms, a half bathroom and an ad hoc wine-storage room. The walkout basement holds a one-car garage, a very large workshop and a fallout shelter.
