Here are a couple before and after pictures as well as a couple of pictures of the kids "helping".
You can just see Benjamin's little face peaking over the gate at the bottom of what used to be the stairs. Daddy is standing on the basement steps.
Here's Anna with Daddy at the top of the basement steps. This picture was taken at what was the bottom of the steps going upstairs.
Here is the underside of the new steps going down to the basement, we put in insulation (our house has none) and drywall to replace the old plaster & lath we tore out.
That was quite a project! We were hoping to have it done in one day, but it didn't work out that way, so we had to spend the night downstairs (our bedrooms are upstairs). We dug out the little tent we had for the kids to sleep in and they had a blast!
