Here is a progression to date of the basement family room project. The overall interior dimensions of this room when complete will be about 10' x 12'. The TV & entertainment center will be on the right in the picture below, along the southside wall. Straight ahead below (the east wall) will have two craft cabinets. The sofa will lie along the newly constructed wall to the left (wall #3 below).
The relevant quarter of the basement, as it looked when we moved in.
The first wall, framed.
The second wall framed. Note the heating/ac vents on the ceiling. We had to frame those out. We'll be putting in a drop ceiling, and a couple fluorescent light fixtures.
The third wall framed. The pillar you see on the right, will be the left edge of the door frame. We're putting in two 36" wide solid-cherry bifold doors (just ordered them today). That leaves just under 2' between the door and the southside exterior wall.
This is the view of the stairs from inside the family room under construction. To your right is the "third wall". The fourth wall is straight ahead (open in the picture). We have framed this space as well. The pillar above is now on your left in this photo. Between pillars is just under 8'. We'll be putting up three large heavy duty shelves on the stairside of this wall, to serve as pantry storage.
And here is the view from today (the white blotch on your left is the pillar): four walls framed, electrical conduit and boxes in place, moisture barrier installed, insulation up. You see the one of the ventilation chases above.
