Hello? For your reference? I see your problem this way. Before building a house, you need to apply for approval at the next higher level, and construction can only start after approval. When building a house, we should also consider the height of adjacent houses along the street, and we should also consider policies and regulations on some issues.
This is a happy thing, indicating that your construction site has been approved. As for when to start work, you can ask questions here to ask netizens to recommend a start date for you, or you can ask friends to help you choose a better day.
Thank you for your question.
