The first trick is to see if the wall outside the floating window is the main load-bearing wall. If it is the main load-bearing wall, don't hit it. If the outer wall of the bay window is a secondary load-bearing wall, it can be pushed down, but don't forget to reinforce it in time to avoid potential safety hazards. The main load-bearing walls are shown below. The bay window was demolished only to find that it was full of steel bars, and it had to be rebuilt with cement. The gain is outweighed by the loss.
The second trick is to see whether the structural form of the bay window is cast-in-place or post-built. Cast-in-place bay window, below the bay window board is outdoor, which is easy to cause safety problems and the cost of barely destroying and rebuilding will be higher. It's hard to please.
The third measure, if you want to play a load-bearing wall, you should discuss with the property. After going through some formalities, the property can only play if it is agreed.
