LA Live/Staples center owner AEG (which also runs the LA Convention Center and various concert promoters) is officially moving into South Park's Desmond warehouse building and the mega-company has big plans for the 98-year-old building. AEG's new landlord, Lincoln Property Company, is now converting the building—originally a car dealership/assembly plant—into creative office space and adding ground-level storefronts, including a cafe; they'll also add a sixth story in the form of a glass pavilion on top of the existing roof. Skidmore, Owings & Merrill is designing the addition, which will bring the building's space to 82,000 square feet. Desmond is also undergoing a seismic retrofit that involves new windows and interior finishes, but will leave the high ceilings and rooftop views. The work will take another eight months, just in time for AEG to move about 500 employees into the Desmond in April. AEG brags that the building as directly on the route of the forever-in-the-works Downtown Streetcar, while the 24-story mixed-user long known as the Glass Tower is supposed to start work soon a block away at Grand and Eleventh.
