When I consider that I have accumulated over $7K in equipment, it only makes sense to spend some money on flooring, paint, lighting, sound and maybe paneling.
The pictures are my primary source of inspiration.
I only have 2 walls to do. Roughly 35 x 9 = 315 SF of painting. I would like to go two tone and I do not want to paint the ceiling. I have a window in the space, white board, chalk board, hspu board, (3) multi-use wall hangers, clock, timer, barbell storage and pull-up bar. These would be removed. I would clean and paint. Then they would be reinstalled. Paneling looks really slick, but is not practical for my space. There is too much wall mount stuff to work around.
I do want to upgrade the lighting. The Barrina solutions on Amazon are easy to install, reasonably priced and a very nice upgrade. I typically would train during the day time, but this is more for completeness sake.
I do not want a television or speakers. The garage being right below my daughter room, really does not need anymore noise than me dropping weights. I have used a blue tooth speaker in the past, but currently I prefer playing Sirius XM radio through an Amazon Alexa device.
I will stick with stall mats. My garage is too uneven to consider flooring rolls unless I got a screaming deal on materials and professional installation.
First step will be to layout the space again and make sure I still want everything where it is currently located. I have to work around the garage door and window. The biggest fixed items are yoke, pull-up bar, mass storage system and plate holder. Everything else floats. An ideal space would preserve an 8x12=96 square foot space for workouts with everything stored in the remaining 200-96 = 104 square feet of space.
