We are planning on building a house in a couple of years and also plan to GC it ourselves. Before we commit to a plan or any of the details, we are hoping to gain some insight or advice from people with experience on this topic. What I am mostly looking for now are the biggest regrets you may have with the choices you have made in your own homes. ie; The "I wish I would have" or the "I wish I never did" What were the biggest mistakes, what would you change next time? Also, what feature, layout plan, or design detail could you never live without and are glad you did?
