Just two months after renderings were revealed for their upcoming Spring Street apartment tower, Holland Partner Group (HPG) is cooking up plans for a follow-up project across the street. Yesterday, the Vancouver, Washingon-based developer filed plans with the City of Los Angeles to construct a 24-story residential tower at 732 South Spring Street. The project, slated for a .93-acre parking lot which abuts the Great Republic Lofts, would consist of 308 apartments and approximately 7,200 square feet of ground-floor commercial space. Further details about the proposed high-rise building are unclear at this point in time. The upcoming residential-retail complex is one of numerous high-rise projects in the pipeline for Downtown Los Angeles’ Historic Core, including a slender hotel tower planned for Spring Street and a 38-story condominium building slated for the southwest corner of 6th and Main Streets. Recent months have seen Holland Partner Group invest heavily in the Central Los Angeles market. Besides their proposed Historic Core towers, HPG is currently in the midst of construction on two low-rise complexes in City West and Little Tokyo. Additionally, the developer has revived a scuttled pre-recession plan for a 28-story apartment tower at the intersection of Figueroa and 9th Streets.
