Yes people still get them. Not all mortgage companies do them anymore. You will need land, blueprints and bids. Usually a title company releases fund (draws) when needed. Many limit the amount of draws that you can do. Also, shop around for the amount of time you can have the loan before it has to be complete - although most will give extensions. Some allow for "self builds" and other don't. Talk to a reputable financial institution and they can give you more specifics based on your needs.
Good luck!
