Vacant since the end of World War II, the famous 100-year-old Historic Riverside Ironworks Building was once the headquarters of Food Machinery Corp., which produced citrus packing equipment, and then world war II amphibious military vehicles. In 2000, Mr. Mruvka bought this 40,000 square foot brick structure and meticulously restored it into a first class luxury office building. The interior of the building is a showcase of contemporary design set within the red brick walls of Riverside history. Mr. Mruvka brought his twenty years of New York historic renovation experience to create a project of world class design that is now home to five Fortune 500 companies including: Wells Fargo, Bechtel, Fidelity, Wachovia, and Jacobs Civil Engineering. Designed by Farshad Azarnoush, Principal of Atelier Architects in Sherman Oaks California.
