Prominent local real estate firm Jamison Services, Inc. has filed plans to build more apartments behind one of its office towers in Koreatown. The proposed development would create a 117,000-square-foot structure atop a parking garage at 678 S. Ardmore Avenue, containing 123 residential units. Plans call for the addition of five floors atop the two-level garage, creating a seven-story edifice. Jamison is also pursuing a similar project a short distance away on Western Avenue, where plans call for the addition of five floors of apartments atop a four-story garage. Another developer has also proposed adding residential units at a parking structure on 6th Street. Architecture firm MVE + Partners is designing the project. Though the company has historically focused on trophy office properties, the past several years have seen Jamison take an aggressive turn towards multifamily residential development. This includes the conversion of several underperforming office buildings, as well as an ambitious pipeline of ground-up projects. The company is now in the planning stages for numerous towers along the Wilshire corridor, and is partnering on twin 36-story buildings in Downtown Los Angeles.
