Build New House In My Name On Wife's Land

I want to build a new house on my wife's land. I want to own the house in my sole name.

My wife will buy the land in two month. That will be no problem.

I want to register a lifetime habitation right on the land.

Can this be done at the land office without lawyer and without a long contract?

Is a VOA enough for the registration?

Does anybody know the thai word for the habitation right?

The builder told me he will apply the construction permit in my name.

Any special requirements for that (concerning my name)?

When the house is finished I want to register it at the land office in my name.

Is the construction permit, the habitation right on the land and if needed a confirmation of the builder that I pay for the house, enough to get the registration?

What kind of paper I will get from the land office?

After that will I be able to apply for the yellow tabien ban?

Thank you very much for any help.
