And to answer the original question, for a major renovation you might be best to talk to the strata manager, building manager and committee about how they would like you to proceed, then use that information to move a by-law that has their blessing (but not approval, which they can’t give) at a general meeting.
Again, larger schemes should have a catch-all by-law that all owners seeking renovations can sign up to, rather than everyone having to start from scratch every time a reno is planned.
