My youngest left for college this year, leaving us as empty nesters. We were also house hunting. So with no more kids at home, we bought a home with both living room and family room. The family room is my sewing room. No door or closet, but I finally have all the space I've dreamed of for years.
In our last home, my DH converted an old workshop outbuilding to a finished sewing room for me. Even in my 30's proximity to the bathroom was an issue. I start sewing and loose track of time, then stand up and that house seems miles away, lol.
