Kim, a South Korean actress who plays Sun Kwon on The Walt Disney Co.-owned ABC series, said she plans to move into the Summit on Sixth condo development when construction is complete later this year.

Kim reserved a one-bedroom unit with a den, which generally sells for between $660,000 and $880,000, sales director Tamara Kim said Tuesday.

The actress will promote the luxury condo project in Korean- and English-language magazine and newspaper advertisements, according to developer Big Rock Partners LLC. She reserved a unit while meeting with developers about promoting the project, said Big Rock spokeswoman Phyllis Hu.

"When I toured the property, I was really impressed with the design and its central location," Kim Yun-jin said in a news release.

The building sits at the intersection of two major streets cutting through Koreatown, a bustling 5-square mile area of central Los Angeles featuring hundreds of Korean-owned businesses.

Tamara Kim said the developer was eager to recruit Kim Yun-jin as its spokeswoman for the 11-story project because of her appeal to a broad swath of potential Korean and Korean-American buyers.

Kim Yun-jin became an international star with her performance on "Lost" after an acting career that included a starring role in "Swiri," a 1998 movie considered the first South Korean blockbuster.

"She's very popular in Korea and she's well known in the Korean community here," Tamara Kim said. "She has a wide audience."

Kim Yun-jin spokeswoman Chantelle Aspey did not immediately return an e-mail seeking comment.
