As for compensation, it is based on both household registration and area. Only the maximum area of personal homestead is limited, so you can go to your place to check the relevant government policies.
There is a question that needs to be clarified here, that is, whether it is really demolished. The date announced by the government is a key point. If the demolition is really carried out and an announcement is made, it is illegal to build houses for compensation and will not receive any compensation. If it's just a rumor and it's not announced, the house built now will be compensated in the future.
