Something I learned from a book somewhere which has worked well with me was to get some graph paper (1/4″ squares) ea square represents 1 foot. Then precisely measure all your furniture and cut out accurate scaled squares out of cardstock to represent everything in your room and lable them. You can now move these pieces of card around on the graph paper to see what set-ups will fit/work the best.
My room is 14X14 and I have most everything in 4 – 7′ racks (if they would only stop making all this new stuff). One thing that helped immensely was eliminating the area behind the racks you need for access to the back of the gear. This area was about 2′ and it was still tight to access equipment back there.
THE SOLUTION: Since there was a regular hallway behind the wall the racks were infront of, I was able to build the back of the racks into this hall wall. The hallway still works as a hallway but the back of the racks are along one side. The racks all have nice mesh doors so it actually looks cool in the hall. The side pannels of the racks have all been removed except the end ones so all the wireing goes through the sides from rack to rack. There is more room to access the back of the gear and I made the editing room 2′ bigger by eliminating the old access space.
This type of renovating is not always possible but what an advantage it has been for me.
