For those who don't know, I'm a Star Trek geek. Mostly the classic series, then Next Generation. Deep Space Nine was something I didn't get ito, but I always loved the design work that was seen. I never thought of building the station, though. Jaco van der Molen did, though. What you see is the result of four drafts and seven years of work. What's really nice is that he has directions available as a PDF download here. (15MB, about 50 pages)
You can see a Brickshelf gallery of the iterations of the model here.
