It's important to consult with a structural engineer and a contractor to assess the feasibility of the project and ensure that the existing foundation can support the additional weight of the pool. Additionally, waterproofing measures will need to be taken to prevent water damage to the basement. Proper permits and building code requirements should also be considered before proceeding with the project. **
