An extensively updated and snazzily decorated treehouse-like cottage — cleaved to a steep hillside just above Hollywood Boulevard in the Laurel Canyon area of Los Angeles and owned, per property records, by television producer Greg Gugliotta — went up for sale in late October with an asking price just shy of $1.3 million. According to online listings, the property is already in escrow, to be sold for an unknown amount to an unknown buyer. Gugliotta created the NBC franchise “Behind the Camera” and currently executive produces the highly rated drama “The Fosters.”

It’s a daunting, multistory climb up a carefully engineered staircase that ascends from the street-level garage to the multilevel aerie, which has just one bedroom and one bathroom in about 900 square feet. The living room features an exposed-wood cathedral ceiling, newly installed wood floors, a built-in media center next to a massive stone fireplace, and a series of glass doors that open to a canyon-view deck.

Raised-panel wood doors at one end of the room slide open to reveal a tiny hidden office space. The dining area, on the mezzanine level overlooking the living room, has custom leather-banquette seating and a wet bar with an under-counter beverage fridge. A few more steps up from the dining area, the kitchen is decidedly compact but smartly arranged and expensively outfitted with custom cabinets, stone counter tops, and top-grade, stainless-steel appliances.

The cottage’s bedroom, which has a wood-beamed ceiling and filigreed-wood screens over the windows, incorporates a dressing area lined with built-in wardrobes, and a bathroom with wood-paneled walls and a basket-weave-patterned, marble-tile floor. A large laundry room has a long, cushioned window seat and a view over one of the property’s decks that are carved into the hillside and provide serene canyon views.
