The West Randolph Ogilvie center benefits from being located in a vintage loft office building in the sought-after West Loop submarket of Chicago's Central Business District. Its strategic position at the corner of Randolph/Jefferson offers high-visibility and means the city's Ogilvie and Union rail hubs, plus Interstate 90/94, are very close by. The seven-story host building's traditional buff-colored brick exterior, with large floor-to-ceiling windows, is contrasted by contemporary interior designs and systems. Chicago Loop is the second largest commercial business district in the US, after New York City's Midtown Manhattan. It is home to financial institutions, stock markets and banks, as well as the headquarters of many international companies. It is the seat of city government but also boasts retail and entertainment amenities.Chicago has a very diversified economy, featuring everything from manufacturing to web start-up companies. It continues to be a major transportation and distribution center and a popular venue for conventions.
