Can you imagine creating a vegetable or cactus garden on your roof? Or planting grass and camping out under the stars surrounded by magnificent sugar-maple, beech and pine trees? This is all possible at a very unique terra dome home at 214 Diamond Hill Road in Hopkinton, Rhode Island’s Village of Ashaway.

Situated on 5 acres of land that borders the the Hopkinton Land Trust, this earth-sheltered house blends in with the open and rural landscape. A magical, long paved driveway transports you to this one-level, ivy-covered home with a front stone façade and driveway in front of the attached 2-car garage, and another on the opposite end.

Enter into a foyer with a coat closet and a log storage cabinet (that can be loaded from the outside). Pass through a curved and very wide archway into an airy and sun-filled open space. A soaring, curved ceiling crowned with a dome skylight creates a dramatic effect.

The large family gathering area features a stone fireplace with a wood-burning insert and sliding glass doors that open onto an expansive patio with a pergola and large wooden table and benches. Carpeting flows throughout most of this home.

Interestingly, one of the benefits of this charming home, is that it is very quiet. However, you can still hear the songbirds and tree frogs outside.

The adjacent dining area is located next to the tiled kitchen, which features stainless-steel appliances, deep pine cabinets with a pantry and storage area. A blue-painted island with a breakfast bar and cabinetry lining a nearby wall add the perfect amount of color to the décor. Also, exposed pipes and open shelving create a modern, industrial flair, while repurposed countertops add a rustic touch.

The elegant master bedroom suite contains double/single closets and a private full bath with a tub/shower, vanity sink, shelving for linens, crown molding, and wainscoting. Another bedroom with a closet features a lovely tree mural. Both bedrooms contain curved archways and a separate seating/play area with sliding glass doors that open to the outside.

A third bedroom with 2 exit doors provides a mirrored sky tube and a gorgeous built-in desk with cabinetry and open shelving.

All 3 bedrooms offer domed ceilings and a loft area for playing, reading, or storage. A second full bath with a shower serves family members and guests.

Also, a tiled utility room contains the washer, dryer, overhead cabinetry, and heating/air-conditioning unit. A door leads to the oversized 2-car garage with a domed ceiling, which offers a large built-in workbench and an abundance of storage space. It also contains the hot water heater, well pump, and breaker box.

How this home was built

Not only is this contemporary terra dome home exceptional and aesthetically beautiful inside and out, it is also designed to lower your maintenance and energy costs. Because the earth stays at about 56 degrees year round, the house stays cooler in the summer and warmer in the winter – saving you a ridiculous amount of money every month. It is also less susceptible to fires, tornadoes, hurricanes, and other types of storms, according to the website,

Plus, because no support walls or posts are needed, the open layout in the main living area and the large patio are ideal for entertaining, interacting with family while making dinner, and keeping an eye on little ones.

This home was built in 1986 with steel-reinforced, concrete – 10 inches on the roof and sidewalls, tapering to 6 inches at the highest point on the ceiling dome, according to the builder’s documentation. The back of the home and roof were tarred with a foundation sealer and covered with a heavy vinyl. Then, 2-inch drain board and 2-inch foam insulation were added, and drain pipes were installed and connected to French drains, which encircle the house. Afterwards, sand, gravel and dirt were added to the roof to keep everything in place. As a precaution, in case they were ever desired later, flue liners were also installed for a furnace or gas water heater, and in the garage for a wood stove (it has never been needed, because it never gets very cold). Also, the cement floors have all been waterproofed with Drylok, so no ground water comes through.

This carpeted 3-bedroom home offers 2 tiled full baths and 2,072 square feet of beautiful, unique living space with domed ceilings. It provides large windows and sliding glass doors, as well hand-built cabinetry, central heating and air-conditioning with floor vents, 200-amp electrical service, a well, and septic system. Additionally, the stainless-steel appliances are only 2 years old. Also, with 10-inch stonework on the front of the home and stained woodwork on the exposed side, there is much less upkeep compared to a traditional home.

Make this private terra dome house your next dream house and enjoy living in a home with extraordinary features and stellar workmanship.  You’re also within the award-winning Chariho School District, 25 minutes from the University of Rhode Island, and minutes from Interstate-95, Westerly beaches, restaurants, and shopping venues. Two Connecticut casinos are also close by. Foxwoods is a mere 20 minutes away and Mohegan Sun is a 30-minute trip.
