The Wilshire Grand Center, a prominent 73 storey structure, situated in downtown Los Angeles, has reshaped the western skyline of downtown Los Angeles and stands as a testament to engineering marvel and finesse. Encompassing around 2 million square feet, this structure seamlessly integrates hotel and office spaces. While the top of the structure features restaurants and a sky lobby overlooking the skyline, the surrounding podium structure include additional commercial spaces for a burgeoning resurgence of the surrounding area. The building was the brainchild of Architect AC Martin Partners Inc while M/s Brandow and Johnson were bestowed to fortify the structure against all natural hazards. M/s Thornton Tomasetti was involved in the performance based analysis and design and M/s Turner Construction Company was responsible to breathe life into the structure.
