@Lowena I've just measured my sewing room - it's only 7' 6" x 7'6", yet I have fitted in a long desk that takes the sewing machine, overlocker and coverstitch along one side, a narrow top for my computer with cube storage underneath the window, then two of the narrow but tall Ikea Billy bookcases, and a big desk for my embroidery machine!
Methinks you're not being very practical with your room
