Standards for examination and approval of rural homestead area planning: (1) The construction area of village (residential) houses shall not exceed 80% of the approved construction land area; (2) The construction area of the newly approved homestead houses shall not exceed 250 square meters; (three) the original reconstruction of the construction area in line with the planning technical standards, not more than 300 square meters; (4) The number of building floors shall not exceed 3, the building height shall not exceed 10.5m, and the roof slope shall not exceed 30 degrees. I hope it helps you. If the rural homestead exceeds the area, it should be an illegal building and should be demolished. The excess area belongs to the collective, but there is no unified area standard in China at present. If you still need to pay attention to the planned area when building a house, it will be troublesome if you need to remove it. For other questions, please visit the lawyer 365 website for details.
