Like others have suggested, having machines on wheels makes a big difference, and it generally not that hard to do. The only tools I find useful against a wall are the miter saw and drill press (also mortiser if you have one). Maybe a bandsaw, but mine is on a mobile base so I keep it in the middle of the room near the power for all the 230V machines (comes out of the floor in my shop).
I really like the Woodcraft swivel casters, but they may not be available where you are. Four swivels for most machines makes a big difference in ease of mobility. Light machines that are roughly square I might use two fixed and two swivel, but for heavy ones I always use 4 swivels. I weld up bases out of angle iron and flat stock, but you can do the same basic thing with wood (baltic birch plywood makes an excellent base material).
