So let's start with some background first. I live in Winnipeg, MB, Canada and currently my father and I are in the process of constructing our basement. We first started a few months ago in January and have been working mostly on weekends. Most of the drywall is up and there are a couple things that we have to finish before the mudding and taping next week.
The basement is 30' x 34' so it is a good size and has 9 foot ceilings (a real plus and I would encourage all future home owners to invest in)
Here is a feature list of what will be included in our basement:
*A 21x 13 home theater area
*Dry Bar
*Computer room/Spare Room (10'x11'
*Washroom (of course lol)
Here is a rough google Sketchup of our floor plan

The top left of the picture is the washroom, to the right of that is the computer room, and finally to the right of that is the furnace room. The bottom left of the picture shows the dry bar, the larger area (ping pong table FTW) and finally the HT area to the bottom right
