We're actively using the space, so I've been working on one quarter at a time. To date, in half of the basement, I have removed all of the old baseboard heat registers, removed and re-routed all electrical conduit and boxes that were mounted to the walls, sealed all of the holes in the walls from the removed electrical conduit and boxes as well as any cracks in the mortar, painted the walls with Dry Lok and the floor with concrete floor paint, insulated the exterior walls with 2" rigid foam insulation, and framed the exterior walls. Below is the second quarter of the basement, with all of the above completed.
Here are the requisite before and after shots of the space.
That odd, small window on the right in the picture was originally a metal door/chute for tossing in firewood for a wood stove. The wood stove in the basement is long gone, and now so is the metal door...which was a major source of cold air intrusion. I had considered bricking in the hole, but having the window installers slip a slider window in there saved me some labor and gives us just that much more natural light into the space. It adds a cool little framing challenge for me, too. One good decision I made with this project was assessing the difficulty of each section, and then starting with the easiest and working towards the hardest. Now that I'm getting into the far more difficult half of the basement I have a bit more confidence from the experience gained in the first half. :)
More to follow...and soon, I hope.
