I also have limited space but what I do is:
I have two, 4 drawer sterlite cabinets, and on top of that I have a "big board' and that is next to me when I am sewing. When I need to do a lot of cutting or pin a quilt I remove the big board, place a paper box ( the box that holds reams of computer paper but is now filled with fabric) on each of the cabinets and put the big board on top of the boxes. It is now the correct height. I then put my cutting mats on to protect the ironing surface and I pin away. I start pinning in the middle and then move it to reach other areas. I have done a king size quilts this. By the way, I made my own board out of plywood, 2 or more layers of warm and natural and teflon material. That way I got the size I wanted.
