Leo Kuhl sat on the edge of a yellow tube. Then he disappeared.
The 6-year-old twisted and turned down the curved, enclosed slide, then landed in the basement below.
"It's fun," said Leo. "But a little scary when it turns."
"It is kind of fast," admitted his dad, Steve Kuhl of his in-home slide creation, "but I didn't want the kids to be bored with it by the time they're 7."
The 26-foot-long tube slide is among the quirky, one-of-a-kind play spaces inside the Kuhls' Hopkins home.
Kuhl also has carved out secret rooms under staircases, tunnels inside closets, suspended bunk beds and built a timber framed loft for his two children, Leo and Charlie, and their friends.
Architecture can play a role in sparking kids' imaginations, said Kuhl. "In this age when we're more virtual, these spaces can encourage kids to interact with their environment."
His kids are lucky that their dad has construction know-how and resources; he and business partner Dan Murphy own Kuhl Design and Build in Hopkins.
