A Seattle homeless man built a “ticking timebomb” cabin — featuring a washing machine and a treadmill — at a public park months after he allegedly stole an excavator to tear up part of the site in his pursuit of gold.

Steven Irwin, 41, claimed he had permission to build the structure in Dr. Jose Rizal Park, despite the Seattle Parks and Recreation Department recently paying $15,000 to repair the damage Irwin had done when he illegally dug up the land in Oct. 2023, according to KOMO News.

Irwin was arrested for the rogue construction and charged with theft of a motor vehicle only to reclaim the space with some interesting upgrades.

The illegal cabin now features fireplaces, propane heaters, a washing machine, multiple generators, and a treadmill.

“He is digging into the slopes, building structures, tearing down trees, undoing thousands of dollars in repairs,” Andrea Suarez of We Heart Seattle, a homeless outreach group that has offered assistance to Irwin, told the outlet Friday.

“There’s also a risk for him being in that environment. There are smells of kerosene, propane, and gasoline – there are three different forms of fuel down here, wires everywhere,” Suarez shared — adding the spot is “a ticking timebomb.”

Irwin’s cabin goes beyond wanting just a cozy place in the park, Suarez explained.

“He’s dreaming up that this is a gold mine, that he’s mining for diamonds, and that he is going to find gold and strike it rich,” Suarez said.

In October, Irwin was busted after multiple 911 calls flooded in from concerned neighbors about destruction at Dr. Jose Rizal Park — which is about 3 miles away from the iconic Seattle Space Needle.

“He was driving a little crazy with this heavy piece of machinery,” said park steward and volunteer Genevieve Courtney last year, who just happened to come across Irwin while he dug up the land.

He would later admit to police that he cleared the space for his cabin with the excavator, still holding strong to his belief he had permission to change the face of the land for his cabin.

Since his release and return to his encampment, Irwin has been using power and hand tools to clear away areas in the park, according to the outlet.

The danger of the situation has also dawned on neighbors living near the park, who have tried tirelessly to get the city’s attention on the issue.

“This guy is just getting away with it, and I don’t understand that. We are absolutely frustrated. We need some civility here, we need police action,” Brian Hartman told the outlet.

Suarez, who wants the situation resolved due to the potential danger Irwin may unintentionally inflict on himself and others, says the homeless man has no plans to stop his building.

However, she said that could only be achieved if the city steps up to the plate and enforces the law.

“This is a call to action by law enforcement and Seattle Parks and Recreation to do something,” Suarez told the outlet.

“I’ve even offered to pay for his first six months of housing, and he said, ‘That’s great. I’m still going to keep my cabin in the woods.”
