Realize you have probably already locked into office space, but for anyone else looking suggest you check out Assemble, a new shared office space in the Gold Coast/Old Town (Assemblehq.com). Tours are available now and the space is set to open Aug. 1, 2014. Private glass offices, flexible month-to-month lease terms and full amenities. Perfect location/setting for traders who need privacy but don't want to feel locked in a closet.
Looks like a Police station. Advantage has office space in Downers Grove with a gym. It has backup high speed connections to the exchanges. http://www.advantagefutures.com/services/trading-facilities/downers-grove/
Downers is nice, but it's far west of downtown. An hour's drive from the city. lol I agree with the police station comment. It's glass because it's centered on the floor. Like a fishbowl.
Funny that someone popped up this old thread now. I just rented a 16x16 office in a class B building 1 block from the Sears tower. Its a large space for one person but it's a corner office with large windows and the price was right. I was thinking it would be nice to have at least one other trader in it for company. But I'll cross that road when I get to it after moving into the space next week. -eLindy
