Lessons Learned From an Early Adopter of Sustainable Home Design
Last Updated: Apr 13, 2025Sustainable home design and building are finally gaining traction. According to Statista, “the green building market is anticipated to be among the fastest-growing industries worldwide.” As with any trend, there are always early adopters—and those are the people Rise likes to talk to gain key insights and lessons learned. Not surprisingly, we found one based in Seattle, Washington.
Way back in 2008, the Seattle-based design-build firm Fivedot co-founders and principals Geoff Piper and Stephanie Ingram designed and built “The Orchard,” a 3,000-square-foot structure as a spec house. Rise recently caught up with Geoff Piper to find out more.
“Seattle had hit a point in the market where there was a demand for modern sustainable housing,” Piper says. “We were seeing the modern market being served, but not the sustainable market—unless it was a one-off, single-family, high-end home incorporating sustainable technologies,” he explains. “Sustainable design had not yet made it to the mainstream market. We wanted to demonstrate how it could be done.”
The large lot that Fivedot had to work with couldn’t be subdivided. “We would have liked to put two smaller homes on the site, but weren’t allowed to,” he says, “so we decided to go a bit bigger with a four-bedroom home, which was designed to be as simple to operate and as sustainable as possible. The less complicated the house, the easier it is to maintain.”
Here’s a look at how Fivedot designed the modern sustainable home and, over ten years later, what the firm would have done differently.
Simple, Passive Design
“Our first priority is always to build a structure well. Quality lasts. That’s the most sustainable thing you can do,” Piper says. The second was to create passive systems. One was for cooling. “We designed the house around an open stairwell shaft that goes up to operable windows at the top, for a stack effect. Because hot air rises, the house can be easily and efficiently cooled by opening the windows.”

Another was for daylighting. The double-glazed, Low-E, and argon-filled windows were positioned to bring in maximum sunlight, and designed with enough glazing to minimize the use of artificial light during the day. In 2008, the windows installed exceeded Seattle’s progressive energy code, Piper says.
At the front of the house, along the high-traffic street, Fivedot placed several concrete tanks that act as a sound barrier, create an entry court, and hold rainwater from the home’s rainwater collection system. "The house doesn’t hide its sustainable aspects but shows them off proudly, as design features that add to its unique and intensely local quality," says Piper.
Rainwater is collected off the roof and funneled into the tanks, filtered and treated, and brought back into the house for flushing toilets and for use in the washing machine. “Reduced water usage means less potable water gets flushed into the sewage system,” Piper adds.
Inside the home, an on-demand gas-fired boiler provides radiant heat installed beneath the floors. A solar hot water pre-heat tank heats the water. The concrete floors on the first level include 15 percent fly ash, a by-product of coal production. The casework was crafted by Kerf Design in Seattle, using only formaldehyde-free, sustainably harvested, Forest Stewardship Council (FSC) certified wood.
The kitchen and bath tile contain recycled content. The fireplace surround and countertops are from Paperstone, a solid-surface material made from post-consumer recycled paper. The open stairway and floors on the upper levels are bamboo, a fast-growing material that’s sustainably harvested.
Throughout the home, low-VOC paint, formaldehyde-free plywood, and prefinished floors minimize off-gassing. The radiant-floor heating eliminates the need for air ducts that can accumulate and redistribute dust and other particulates throughout the house.
“The design is fairly simple and uncomplicated, but rectilinear and straight,” Piper says. “To offset that angularity, we incorporated moments of beauty in the interior décor—often using repurposed or salvaged items—to provide more soft-edge contrasts.”
