I haven't read all the comments, because I know that same of them will just irritate me.
I think you need to be sure it's what you want and that whatever level of risk there may be, you are comfortable with that. There is a lot of good information on the Homebirth website, which I notice that someone else has referenced. Contrary to many peoples' opinions, the risk is not what they think.
The only thing I would suggest is having a midwife with whom you are comfortable and who you trust. I, personally, wouldn't want to end up with some jobsworth who wasn't confident in her practice outside a hospital and would transfer me in at the first sign of it not being a textbook labour.
I also developed a siege mentality at the end of my pregnancy when various people with no informed knowledge on the subject started trying to scare me into hospital.
I was going for a homebirth against medical advice and with an independent midwife. However, the foolish child turned during labour and, from a good position, ended up in a bad one and wasn't going anywhere - and I ended up transferring in, where she was delivered by c-section. This notwithstanding, I wouldn't change anything about the labour itself (although slightly shorter would have been nice!) and would make the same decision again. I could move where I wanted, pace the garden, eat my own food, play my own music, deploy ice packs and hot water bottles when required and use my own bath / inflatable birthing pool knowing they were clean.
It wasn't just that I was indulging myself by having a touchy-feely birth experience, I just wasn't going to be set up for a fall by birthing on the main labour ward, having been denied the birthing centre. I tried to give myself the best opportunity to avoid a Caesarian. Didn't quite happen like that, but I'm happy with the course of the labour and felt in control.
The reasons my consultant gave for not liking the home birth plan were reasonable enough - they were his professional opinion - but the post-partum monitoring that was supposed to be so important for myself and the child seemed to fall by the wayside, even when we did go to hospital. So not that important in the event. Also a red herring was the transfer time - it's not like I live in the Outer Hebrides.
I think that some people fail to appreciate that not everyone is reassured by hospitals and a medical environment. And stress affects the course of your labour. On a previous thread similar to this, someone remarked that they couldn't even have a bowel movement in a public toilet - how could they be expected to give birth in a hospital.
Good luck.
