Tens of thousands of years ago, a glacier slid its way through southern Alaska and carved out the Matanuska-Susitna Valley. Bound by three massive mountain ranges and dotted with lakes, it’s an unabashedly wild place. Hundred-pound cabbages flourish in endless summer sunshine, caribou outnumber people, and towering Denali presides over it all. “You can go 1000 miles here without crossing a road,” says Martin Buser. “Most people can’t grasp that kind of freedom.” A four-time winner of the Iditarod—the grueling dogsled race from Anchorage to Nome—Buser spends his days crisscrossing the landscape with his dogs. So, for his dream home with his wife, Kathy Chapoton, there was no question that the spectacularly rugged setting needed to be the driving force behind the design.

The story of how the couple met and found the site is typically Alaskan. Chapoton moved from New Orleans to Anchorage in 1979, at a time when the state government let people claim land for pennies as a way of getting back tax dollars. Soon after relocating, she joined a group of friends one day in early January to stake out the five acres allowed to each person. “It was 50 below zero, my teeth were frozen, I didn’t even know how to read a compass, and I had to walk around and literally mark the parcel,” she says. “It was hilarious.” Registering her claim at the office in Anchorage, she bumped into Buser, a recent Swiss transplant, and the two married not long after.

For 20 years, the growing family (sons Nicolai and Rohn are named after Iditarod checkpoints) lived in a large house that Buser built on the land, adjacent to the kennel where his hundred-odd dogs reside. In 1996, a wildfire swept through the area: “It was pretty ugly,” remembers Chapoton. As a result, people started selling off their nearby plots, and the couple snatched up 25 additional acres—including a mountaintop site that they had been eyeing for years. “It was the primo lot,” says Chapoton.

Buser built a little cabin on the top of the mountain as a weekend retreat, but the combination of killer views and the couple finding themselves empty nesters convinced the pair to make that site their permanent home. They moved the cabin by truck to a nearby site (son Rohn lives there now) and called on architects Petra Sattler-Smith and Klaus Mayer of Anchorage firm Mayer Sattler-Smith to design a house. Though Buser had built several homes, the couple knew this site deserved something special. “Because of the multitude of views, we couldn’t take advantage of the site ourselves. We knew our limitations,” Chapoton says.

Everything about the 2,450-square-foot house centers on the natural setting. “It was important to have every room look to Denali, which is the ultimate view in Alaska,” says Mayer. To do so, the architects created a long, lean, L-shaped house. The blackened, local spruce cladding pays homage to the area’s wildfire, while also mimicking a glacial erratic—a nonnative rock deposited by a moving glacier. The courtyard and part of the kitchen are slightly offset, following the lines of the site’s hilltop topography, while the rest of the house points directly to Denali National Park.

Inside, the walls are paneled in Alaskan yellow cedar, as if the charred exterior has been peeled back to reveal glowing, living wood inside. The public areas lie in one long sight line that starts in the courtyard outside, streams through the living and dining rooms and kitchen, and slips out onto the northern horizon through a wall of sliding glass. The other side of the L contains he bedrooms and bathrooms, each with its own framed outlook on Denali. Windows in the hallway and in the family room face south to let in extra sun during darker winter days. There’s also a rooftop deck, perfect for the family’s many parties—where friends grill mooseburgers and take in the star-filled sky and 360-degree views of the mountains.

Lest the house seem too fancy for these frontier surroundings, it’s important to remember that Buser built the place himself over six years. Here, there are no construction codes in rural areas (“Building permit?” scoffs Buser. “What’s that?!”), and people prefer sweat equity to bank loans or subcontractors. “When Alaskans say they’re building a house, it means we’re swinging a hammer, digging in the dirt, and trimming it out,” says Buser. Yet, this DIY ethos meant that Buser’s solutions were sometimes those of a would-be MacGyver. He and Chapoton charred the cladding using a weed burner and a garden hose; the 800-pound glass doors were lifted into place using Buser’s rigging of dogsled runners, pulleys, and brute strength; and he sliced open two birch trees to make the dining room table.

At the end of a typical day, Buser comes home from an 80-mile dogsled ride as the last rays of sun linger on the mountains. Inside, Chapoton (now retired from teaching) whips up a salmon meal for ten, and the gregarious couple shares wine with friends around a crackling fireplace. When everyone’s left, Buser and Chapoton will tuck into their bed, watching the vivid hues of the northern lights dance through the windows. Says Chapoton of her love of the house, “Maybe Einstein said it most simply: ‘Look deep into nature, and then you will understand everything better.’
