I bought a building but found that there was a load bearing beam in the living room of the building

If it is not a problem with the quality of the house, there is a chance that it cannot be replaced, because the house has long been filed with the Housing Authority. The design of load-bearing beams is usually to ensure the quality of the house, whether it is beautiful or not is secondary. It is suggested that you can solve this problem by renovating.

It's hard to change, you can only negotiate with the developer to see if you can redesign or change the load-bearing beams of the house!

No, if there is no special agreement in the contract, it is definitely not possible

There must be no way to change it, the contract has been signed, didn't you go to see the house when you bought it?

It's more difficult to change estimates, but you can ask the developer for a try. If it doesn't work, make half of the open partition under the beam when you decorate yourself, and don't decorate it into a pattern where someone will sit under the beam in the future.
