I impulsively bought the two neighboring houses, planning to knock down the walls and create a large open-plan space.

As soon as I finished demolishing the walls, I saw that they were all reinforced with steel bars and pipes, and I panicked on the spot.
I asked the property management, and they said I must have a professional organization assess it; otherwise, I can't continue the renovation.
Now the more I think about it, the more scared I am—what if I accidentally removed a load-bearing wall, and the entire building is at risk?
Does anyone experienced in renovation, please help me check if I can continue? Did I cause a big problem? $ETH
