Holland Partner Group (HPG) continues its construction binge in Downtown Los Angeles, with yet another residential tower slated to break ground today in South Park. The Vancouver, Washington-based company’s latest development - slated for a half-acre site bordered by by Figueroa, 9th and Flower Streets - will be a 28-story, LEED-Silver building which will feature 341 apartments above a three-level underground parking garage.  The project, known as Apex II, will also include approximately 11,600 square feet of ground-floor commercial space, a rooftop amenity deck and a small park. Designs from architecture firms Gensler and the Preston Partnership call for a contemporary 312-foot tall structure, clad with glass and metal.  The Figueroa side of the building will be adorned with a 6,500-square-foot LED sign, similar to those seen on other towers surrounding the L.A. Live complex. The tower was first envisioned over one decade ago by developer Sonny Astani, who had planned for a multi-building residential complex known as Concerto.  Although Astani completed one of the two proposed towers, as well as an accompanying seven-story building, the bankruptcy of his lender eventually forced the sale of the property, which was rebranded as Apex. Completion of Apex II is currently scheduled for late 2018.  It is one of five ongoing projects in Downtown for HPG, including two towers on Spring Street, the Sixth & Bixel development in City West and an apartment complex near Little Tokyo. A similar high-rise development from Los Angeles-based CIM Group broke ground last week on a property one block east at 9th and Hope Streets.
