I'm very proud of this project. It was mostly my plan from start to finish, Dave just helped me execute my vision ;)
Before: We had this creepy hole in the wall lined with cedar. It was a lot of storage space, but most was inaccessible because it was too deep and too high. So it functioned more as an ugly clutter-collector.
At this point I had removed the old trim, and installed one of the new bookcases.
I think the pictures speak for themselves. You can see a little knob in the left bookcase. This is a door so that all that space behind them can still be used to store items that don't get used often.
