I started with hope and joy and a few modest must haves......2 years on older, poorer and possibly wiser I was just desperate to get to the end. Of my must haves some are here and some are not. I learnt to my cost that unattended builders take the easy route which does not necessarily facilitate the must haves and then it can be impractical, impossible or just too expensive to undo what has been done. You need a padlock on your wallet and eyes in the back of your head...oh and give up the day job. Its what I ended up having to do as things were clearly going wrong. I have no experience of managing contractors some (most) took advantage of my inexperience and some (very few) were really nice.
