The other side of the wall is not finished yet. I've had other home improvement projects come in the the last nine months that have taken over my life. But just as a promised here is the 98% completed rec-room side of the built in fish wall. The only thing left to do is put some trim work around the window.
I built the book cases and bench from an ideal I got from my wifes IKEA catalog. I was able to build the bench and the book cases the to the same dimensions so that I only had to design one thing. The shelves are also the same size as the book case sides, and bench seat.
