When I bought the house, I didn't say that I would build a slide downstairs. What should I do if a slide is built in the later property?

The following solutions can be considered:

1. Negotiate with the property: You can contact the property management department and explain that you didn't know there was a plan to build a slide when you bought the house. I hope they can solve this problem. Through consultation, you can ask the property to provide reasonable solutions, such as removing slides or making other adjustments.

2. Seek legal advice: If the negotiation with the property fails to reach a satisfactory solution, you can seek professional legal advice. According to local laws and regulations, you may have the right to ask the property for compensation or other compensation measures.
