Hi i don't seem to be able to find an answer for the following in BCA guidelines. My condo was built 5 years ago.

1. Are we allowed to remove balcony sliding door which separate the living room and balcony?

2. If yes, can we level up balcony flooring so that it becomes the same level as the living room ? ( Becos I intend to do the same flooring for both living room and balcony)
I noticed those who did balcony decking, their balcony was raised to similar height too.

Hope that some experts can share your opinions.
