Do what I did. When DH was on a trip I converted the den to my sewing area. When he came home the carpet was ripped out and a closet was being built. I had told him I wanted to do this but he dismissed it and said it wasn't a good idea and then went to his ac/heated work shop addition to the garage. I guess he thought I would agree with his decision. I did yield to not have a wall torn down when he said it may lower the resell value. He was happy I agreed to keeping the wall that he didn't care about losing the den that no one used but the kids anyway. The kids didn't get a say so in the matter.
