Kids Empire, a children’s indoor playground, has signed a 5-year lease for 10,141 square feet of retail space in the Warner Center area. The space at 6400 Owensmouth Ave. is under construction. This is the ninth Kids Empire location to undergo construction this year and the sixth in California. “The Woodland Hills location is across from the Westfield Topanga Mall that draws 22 million visitors a year,” said Stephan Ktorza, commercial real estate broker. “This kind of traffic will be great for Kids Empire.” Ktorza and Shelby Dopps, both of Kidder Mathews, represented Kids Empire in the transaction. Capital JTA, the landlord, was represented by Todd Nathanson and Carter D’Auria with Illi Commercial Real Estate.
