Your midwife has no say in whether you're 'allowed' a home birth. It's your choice. If you are unusually high risk, they can and likely will offer their advice on what they feel might be best, but the final decision is yours. They have a duty of care to you and you can decide at any time if you want to stay at home, even after you're already in labour. You just have to call any tell them and they are required to send two midwives to support you.
Here's a good list though of what you might need, along with lots of other good info:

Best advice though: plan it and believe it will happen. If you're afraid or go into it thinking it probably won't happen the way you hope, it won't. You really have to believe in yourself and trust your body because you really can do it. Those of us who have homebirthed aren't super-human or stronger or better able to deal with pain, we just trusted ourselves, felt confident about what we were doing and surrounded ourselves with the right support.
Btw, have you thought about a doula? One might really help you feel stronger and better supported leading up to and during your birth.
