Multistory Mount Baker treehouse on the market for $600K

This four-bedroom, two-bathroom garden cottage in Seattle’s Mount Baker neighborhood is just a few blocks from a light rail station and set-up to be used as an income property. But let’s be honest: that treehouse though.

The home’s multilevel, cylindrical eco-treehouse out back is a sight to behold. The property owner’s ambitious plan was to create a comfortable, unique space for his musician friends to stay while they were on tour. Originally from southern Alaska, he used yellow cedar from that region as his primary treehouse-building material.

A spiral staircase with branches for handrails leads from a below-grade fire pit to the main home’s deck. The passively built dwelling emanates upward from there. Construction began in 2016 and two habitable stories—with ample natural light and working electricity—were built around a single backyard tree.

Although work remains to be done to complete the homeowner’s original vision, more than $90,000 to date has been put into creating what he’s calling “Rainier Cherry Treehouse.”

Now that we’ve adequately geeked out about the treehouse, we can take a look at the main house, which stands up on its own—just not in a tree.

This southeast Seattle bungalow was originally built in 1944. It occupies 1,600 square feet and, although centrally located and close to mass transit, is on a quiet, dead-end street adjacent to the Cheasty Greenbelt.

Although the house includes four bedrooms and two baths, it has been split up into two separate homes—each with two bedrooms and one bathroom. This layout means the new owner will have some interesting income property options to weigh. Finish up the treehouse, and she or he could have multiple spaces to rent out. Cha-ching.

Walking up to the front door along brick pavers, you’ll go through an artsy courtyard lined with planter boxes, wood sculptures, and a rain barrel. Both homes-within-a-home include wood floors and custom wood features, interesting architectural touches, and plenty of room. From arched doorways and exposed beams to a ship’s wheel overhead, this property is no ultramodern box.

In addition to the treehouse and fire pit, the backyard includes a studio currently set up as a home office and a sizable storage shed with two access points.

This distinctive home, perfect for someone with kids, a kid-at-heart, or someone looking for an interesting source of income, is on the market for $599,999.
