As others have asked, type of building (storeys, size)? Structure of building (wood framed or concrete)?, etc.
Having built condo/ apartment buildings, if there is a wall, there is very likely base building services (electrical/mechanical) inside that wall that can’t be moved, without screwing a lot of other things up.
Also, any structural work requires a building permit. Any structural work in a condo should not be remotely considered without a structural engineer’s stamp, AND full authorization in writing from the condo (who should have reviewed very specific and detailed plans).
