I can heartily recommend designing your own studio using easy to move furniture because, over the years, you'd be amazed at just how often it's been useful to move or rearrange my working-quarters. Sometimes its been because the weather out in my converted porch has been too arctic or Saharan; sometimes it's been to make room for house guests or house plants or visiting other-people's-cats; sometimes its been due to repainting or...
In a weird way, the moves are fun. Working in a slightly different environment shakes up old habits - I kinda enjoy it - and when I move back into my usual space and configuration I always have a few improvements... plus it's tidier!

As you can guess from the black box in the foreground, I am an advocate of the "Box" school of storage - everything for one project goes in one box, in strict chronological order with most recently utilized on top. (File folders? Phoo!) I was heartened to discover that the famous choreographer Twila Tharp uses the same method, just with bigger boxes. I like 'em flat-n-shallow for drawings - I started with pizza boxes.
