A lifelong fan of treehouses, Pete Nelson decided to turn his passion into a business, Nelson Treehouse and Supply, and later starred in his family’s reality show, Treehouse Masters. With the show’s eleven-season run completed, Pete has happily returned to the trees.

Were treehouses and nature part of your childhood?
My dad went to forestry school. He would take me up to Harriman State Park in New York and show me the distinct pattern of birch tree leaves and the difference between white and red oak leaves. Some of my fondest memories, even in winter, are of my dad sharing the peacefulness of the woods. Even as a kid, I knew it was a special place.
My dad built a treehouse for me when I was around five, so from about that age until the time I got my learner’s permit, treehouses were ubiquitous for me. I also built several others—very poorly—which never came to fruition as I had envisioned them in my head. I found myself dreaming about the architecture and the design of treehouses.

What happened next?
I went to college in Colorado and majored in economics. However, I quickly realized that all my classmates would eat me for lunch if I competed with them for jobs, so I asked myself what I could do that’d make me excited for the next fifty years of my career. Designing treehouses was only a dream until 1987, when I had an epiphany that I needed to be amongst the trees and building grown-up treehouses. The first one I built was in my backyard, and I started building more here and there.

However, becoming a full-time treehouse guy was a long and arduous journey. My sweet wife, Judy, was supportive the whole time, thank goodness. We had moved from Colorado to Seattle, where I was building single-family houses. After my epiphany, I spent the next fifteen years working on mostly new residential construction in the Seattle area. I was always in the background researching the work of other like-minded people who were fantasizing about creating their dream treehouses in various parts of the world, and I’d go on little junkets to take pictures. I was also gradually gauging interest to see if there was a grown-up treehouse market.

Things really got rolling when my first treehouse book was published in 1994. That allowed me to share my dream with the world and to start building treehouses across the country.

When did Animal Planet enter the picture?
I got the call from Animal Planet around 2011. I somewhat reluctantly agreed to do the show. I had been approached a number of times during those years about doing a reality show, but I felt a certain level of trust with the Animal Planet people, who promised they wouldn’t cause unneeded reality TV drama, and they were true to their word.

We couldn’t miss our deadlines with Animal Planet, though—their budget allowed us nineteen film days, and that would usually translate to three weeks max on site. We’d literally visit a property one day, design that night, return to the site, sell our ideas, and try to start within a few days.

What has been your focus since Treehouse Masters ended?
We took a bit of a breather in the wintertime—it took me four or five months alone to come down from being the Pete that’s on TV. In spring of 2019, we got back to building treehouses.

We now talk a lot about what our hopes and dreams are as a company. Wherever the right clients are, we’ll travel and build. We take it very seriously, but we like to have a lot of fun, and we’re in that remarkable position of being on top of our game in the nascent business of building treehouses.

Our effort now is not to build every treehouse in the world—but to build the best treehouses in the world. To that end, I want the company to stay small because I don’t want it to get untenable. We really want to grow with intention, rather than by demand, and savor this good time.

What are some of your company’s biggest accomplishments?
I feel so honored that we’ve put out six coffee table books on treehouses. We’ve also created treehouse retreats. We built our first, Treehouse Point, in 2006 in Fall City, Washington, where we’re located, and a second location in Texas. Treehouse Resort and Spa is scheduled to open in 2020 in Redmond, Washington, with twenty-seven treehouses. It’s going to be a supersized version of Treehouse Point. I’m so excited about it.

What has been the biggest advancement in your field?
The hardware that we’re using to connect to the trees. In 1997, Michael Garnier, who had started a treehouse bed-and-breakfast in the early ’90s and hosts our annual treehouse conference, an engineer named Charley Greenwood, and I found that a three-inch-diameter bolt in a Douglas fir could sustain a serious amount of weight: around six to seven hundred pounds. We refined it and developed the treehouse attachment bolt (TAB), which can hold up to ten thousand pounds of force.

I’m delighted by how the trees are responding to this hardware. They’re absorbing it—as the TABs weather and age, the trees just grow their rings around them, and the bolt and the platform level stay where they are. It’s like a gnat landing on an elephant when we put the TABs in these enormous Doug firs in the Pacific Northwest. They don’t feel it; it’s nothing to them.

Besides Douglas firs, what are the best trees for treehouses?
I’ve rarely met a tree that I didn’t like. However, only certain types make for good treehouse trees. In the end, the long-living ones—oaks, pines, maples, Doug firs, and elms—work the best. Red cedars, gorgeous trees that we love so much in the Pacific Northwest, are one of my favorites, too, but they have lots of branches to contend with. The Doug fir goes straight up, sometimes fifty feet before the first branch, and you can just latch onto the side of that tree. The size of the tree isn’t overly critical; I say work with what you have.

What features do your treehouses offer? How long does it take to construct one?
The time frame will depend on the project. Much like ground houses, there are permits involved, and they vary by state. Plus, the standard features have changed over time. The treehouses always had electricity, but composting toilets turned to flushing toilets, and flushing toilets sometimes begat real showers, which sometimes have tile. There were always kitchens with under-counter refrigerators, but now they tend to be full kitchens with real refrigerators. So the three-week project can become more like a six-week project.

Has treehouse living grown in popularity over the years?
To me, seeing is believing. The amount of work being done in the trees is mind-boggling. On Instagram, you’ll see that so many people are building treehouses, in all shapes and sizes. It’s such a viable form of architecture now.

Ultimately, what is the magic of treehouses?
One of my dad’s friends told me something I’ll never forget: treehouses are the perfect amateur project. A treehouse is often how most of us builders cut our teeth. I’d thought amateurism is just where you make something that’s full of mistakes. Learning from mistakes is important, but building treehouses is done out of love. The root word of amateur is “to love,” and, even if a treehouse doesn’t turn out the way you originally envisioned, it’s a labor of love.

Treehouses bring families together and communities together, and they get people outside. Treehouses allow you to get away, disappear into nature, and enjoy the splendor that’s all around us. Your heart rate actually drops when you’re up in the trees. You feel safe. You can breathe a little bit and forget about life.
