Looking at the back wall, on the left side of the riser to the entry, I cut out the carpet and replaced with laminate flooring.
I also added a cabinet and sink (there already was water and drainage).
These are the speakers that I bought.
These are the last set of photos I took until the finished photos in the first post.
I am currently building a candy counter/concession stand from scratch and will follow-up with photos in the near future.
