If you were to ask me to build a bridge and those were the only instructions I was given, I might build a bridge that goes over a river, it might go over a street, it might go over land or might go no where at all. It might be made of concrete, of aluminum or of paper.
If you were to ask me to build a bridge and then gave me the specifications (from Point A to Point B and should be able to support X, Y and Z and should be modeled after G, H and I) there is a much greater chance you will get the bridge you were wanting in the first place.
The more specifics you can provide, the more likely you are to get what you want.
Have a great day!
PS. If you ask me to build a bridge, you will be sadly disappointed, I don’t know how
