The Downtown construction boom continues to spill over the Harbor Freeway, as yet another mixed-use complex heads to City West. Earlier this week, plans were filed with the City of Los Angeles for a new residential-retail complex near Good Samaritan Hospital and Los Angeles Center Studios.  The proposed development, located on a two-acre site at 1111 West 6th Street, would consist of two buildings featuring 362 residential units and approximately 25,800 square feet of ground-level commercial floor area. The developer, Sapphire Equity, is a limited liability corporation linked to Jade Enterprises, a major Downtown landlord whose other holdings include the 25-story Figueroa Tower. Their latest project seems to adhere to Jade Enterprises’ familiar practice of naming their developments after gemstones.  The company is currently in the midst of construction for Onyx, a 410-unit complex in South Park, and Topaz, a 153-unit building in the Historic Core. The proposed complex would sit directly across the street from Bixel & 6th, a upcoming $200 million complex from Holland Partner Group that will also include apartments and retail space. A timeline for the Jade Enterprises development is currently unknown.
