The couple worked with architect Rosemary McMonigal of McMonigal Architects in Minneapolis. They built a 1,500-square-foot cabin for family and friends using SIPs (structural insulated panels) and T-mass (thermomass) as construction methods. "We went with super-insulated construction," Brownlee says. "It was a no brainer for us. We all need to do everything we can, in new construction, to lower our impact and save money." 

"The Brownlees liked the idea of honesty in structure," she adds. "The higher-grade plywood also gives the rustic interior a bit more finish." The roof SIPs have large overhangs that direct water away from the house, and control sun and shade.

The frame walls, at R-37, and the roof panels, at R-43, didn't require any additional insulation. The cabin sits on a slab-on-grade, thermal mass building insulation system (R-17), with continuous insulation in the wall's core.

"Not everyone wants concrete on the inside, but it's a good system for a foundation in this climate, where the snowdrifts up higher than one foot," McMonigal says. The concrete wall also creates a wind buffer, shields the home from adjacent road-noise, and "has a visual interest that they like."  

They sourced windows that bring in plentiful natural daylight from a local manufacturer, H Windows, in Ashland, Wisconsin, just 30 miles from the cabin. The 100-year-old company, originally based in Norway, set up shop in Monticello, Minnesota, before relocating to Ashland to be closer to the wood they use, McMonigal says. "They also felt there was a larger pool of potential employees in the Ashland area that would welcome detail-oriented factory work."

"We used a triple-glazed window, after spending time examining the combinations of glazing to use on the different layers," McMonigal says. "We have a few windows to the North, and more toward the South and the lake to take advantage of the fantastic views." The operable windows also provide cross-ventilation, eliminating the need for air conditioning. Alternating shed roofs add ceiling height and bring daylight deep into the house.

The cabin also includes a bunk room and a sauna. "It's a gathering place," Brownlee says. "People feel comfortable staying here. It has a great vibe, with everything you need in a clean, comfortable, and cozy space, so it's always in use."
