Considering the complexity of the clients’ program — build an angular house on a half-acre, steeply pitched lakeside lot with runoff issues — architects Rolf Kielman and Josh Chafe of TruexCullins in Burlington, Vermont, knew they would need to work in close collaboration with a site designer at the very start. They quickly solicited the help of landscape architect Keith Wagner of Wagner Hodgson Landscape Architecture, also in Burlington. “It was a challenging project,” Wagner says, “but that’s what made it fun. We had a great team and worked together to turn the constraints into something positive.”
Kielman’s vision for a new house to replace one built in the 1970s and expanded in the 1980s drew inspiration from the minimalist Casa Malaparte, the legendary house designed and built in 1942 by Italian writer Curzio Malaparte on a towering promontory of Capri high above the Mediterranean Sea. “Like the Malaparte house, we wanted the house to feel like it had magically emerged from the natural landforms,” Kielman says. To accomplish this, he and his team sheltered the house from the road with a berm that climbs up onto the “green” roof of the garage, then peels back to open the three levels of this 4,700-square-foot house to Lake Champlain. “Closer to the lake, the house becomes glossy, transparent,” Kielman says. “There’s the notion of coming from enclosed and opaque to open and light.”
The landscape design follows the grade of the lot and connects the house with outdoor living spaces all the way down to the water’s edge. Beginning with the auto court, front entry, and breakfast terrace at street level, it descends along a flight of bluestone steps onto the pool terrace, then drops another 25 feet by a generous stairway to a lakeside deck. The foundation and retaining walls of 6-inch concrete, formed with hemlock boards that leave the impression of rough-sawn wood on the surfaces, anchor the house to its site and define the various zones, each offering a different vantage point for enjoying the view of the lake and the Adirondack Mountains. One of the most dramatic is a narrow, asymmetrical deck built atop an existing concrete tower that juts out over the water much like a diving platform.
“The landscape and architecture are well blended,” says Chafe. “Neither would make sense without the other.” But the landscape design is not just about aesthetics. To mitigate erosion and prevent storm water from running directly into the lake, Wagner incorporated features such as succulents planted on the garage roof, a sediment-trapping “rain garden,” and channels for rainwater to feed into landscaped swales.
The narrow lot presented extreme challenges, but the design team decided to “work with it rather than fight it,” says Wagner. The plantings and steps along the south side of the house funnel the view toward the lake. Contractors from Roundtree Construction of New Haven, Vermont, found creative ways to attack the tricky lot configuration and grade changes. For example, they worked on the waterfront deck from a barge instead of on land. “They are superb contractors,” Kielman says. “It would have been a different house without them.”
Because of sun-shielding, cantilevered overhangs, large interior spaces, and expansive, wraparound glass, the house is framed with steel. And everything is wedge-shaped. “There’s only one 90-degree angle in the whole house,” Chafe says. Since the overhangs are both angled and tilted, every piece of steel in them is a different length and cut to a different angle. “[Roundtree project manager] Ric SantaMaria is a great problem solver,” Chafe says. “If you could peel back the plaster, you’d see a lot of sketches on the plywood and studs. Simplicity is hidden complexity.”
Interior spaces are serene — minimalized to give center stage to art on the walls and the view outside. Intersecting planes appear not to touch one another. Walls seem to stop 4 inches from the ceiling, creating coves where lights, heating grills, tracks for hanging art, and in some cases window shades are hidden. Plaster walls are separated from door and window trim by a slender reveal. The staircase has open risers and glass where the balustrades should be. “The intention was to convey a lightness of feel — a floating quality,” Kielman says.
Every detail was deliberately planned by the architects and precisely executed by the builders, down to a steel doorstop matching the band of steel inlaid in a rift-sawn oak veneer door. The owners, one of whom is an accomplished artist, thoughtfully selected fixtures, furnishings, and art that completed the refined composition. “Only once in a while do you get a client who wants to live in a piece of art,” says Chafe.
“The power of the project,” says Wagner, “is the complete integration of architecture and landscaping. You don’t know where the architecture ends and the landscape begins. It’s a marriage of site and built forms.”
