When Brian Littleton set out to combine two apartments into a 3,000-square-foot triplex in Chicago’s Wicker Park in 2014, he had some unusual ideas—an indoor tree house, a “rocket room,” and an electric model train track suspended from the ceiling, to name a few. At the time, he was both a young-at-heart bachelor and an enthusiastic uncle with a niece and nephew, now five and six, who live about a mile away. “I thought, why don’t we build some fun stuff to convince them to come over more,” says Brian, who owns a digital marketing company.

But he didn’t want the interior to feel like a funhouse. So he tasked Studio Gild and Perimeter Architects with creating brilliant play spaces while also making the home elegant enough for grown-ups. “Brian is about ten years old inside even though he’s technically forty-two,” says Studio Gild’s Jennie Bishop. “We were excited to be playful, but our goal was to keep it sophisticated so it didn’t come off as a joke.”

To create the tree house, Studio Gild, working with Bigane Construction, designed a curvaceous loft clad in reclaimed cedar, elevated on metal legs. Inside, the flooring is synthetic turf and the walls are coated in chalkboard paint for scribbling. Behind it is the rocket room, with climbing nets to simulate zero gravity and a control center loaded with retro buttons and dials. This play area can be accessed by a small children’s door installed within a larger grown-up door.

To finish things off, Studio Gild chose upscale materials that are simple to maintain. “A bachelor and a kid are kind of the same,” jokes Bishop. “You want to make it all durable.” Their choices included a custom sofa and ottomans upholstered in easy-to-clean felted wool, washable Mylar wallpaper, and, for the new spiraling stairwell, a mottled Venetian plaster that hides scuffs and fingerprints. The floor is wire-brushed oak with a matte oil finish. “People can traipse in with shoes, roller skates, or Tonka trucks, and it just gets better with age,” says Bishop.

“The design subverts a very standard condominium layout and balances utilitarian and fun moments.” —Bill Bigane, builder

The result is far from a typical bachelor pad, which now appears prophetic—Brian got married last September, after construc- tion was completed earlier in the year. His wife, Breanne, has four-year-old triplet nieces who also love the indoor tree house. “It works out well,” says Brian. “The adults can plant themselves and watch a movie, and the kids can run around like crazy.”
