Re: Anyone build a house?
I advise you to talk to local professionals unaffiliated with your builder. When I had my house built a few years ago, I trusted them and their people. But later, when things started going wrong, and I had to call for professional help, it was discovered that some pretty big corners were cut - which were expensive to do properly... So pay attention to everything, and get independent eyes to look at that which you can't see.
That's why I said hire an architect. To not do that for a new build is folly. Also you need an experienced project manager. Assuming you know what you're doing when you've never done it before is also folly.
They couldn't hit an elephant at this distance.
