I build organically for the most part, adding as I need or want for the hell of it, I build initially for function with a small bit of leeway for expansion, then go over the place and add 'stuff' ... to make it look interesting and not 'plain'.
I put a workbench at each of the compass points of my base at the wall, and check corners to see if there is any part where I cant build which means out of range of a bench.

I often find that while some plans dont work initially, returning to failed projects later tends to be fruitful.
