You know what worked for you in your current home, so could you do that again?

In my previous home, I built my sewing machine into the laundry room cupboards, complete with a flip up lid, so I had full countertop when I was doing laundry, and the machine was protected, but ready to sew when I had the time. The cubbyhole below held a pull out seat with storage, that I used when stitching.
