glad to see that you are trying to make a change in your block.
But in strata, often change can take a long time, if at all. Your fellow owners have elected a committee. If your block is like most others, most owners are uninterested in their block and are happy to have the SM or the committee manage the blocks affairs.
In my opinion a good course of action is to get friendly with your fellow owners. Don’t scare them with how much change you want, because that translates in their minds to higher levies. Tell them how you can add to the management of the block and your interest in being on the committee.
(it’s unlikely you will have much effect unless you are on the committee unless you want to be going to court all the time – and in that case you will just piss off all the other owners)
By getting friendly with the owners and committee members you stand a chance of being voted onto the committee. Once you are on the committee you can start to influence things like what repairs need to be done; budgeting money for future repairs and how levies are raised.
(it’s likely the block is run down because they do not have sufficient money in the capital works fund).
Be considerate of existing owners. You bought into the block knowing it was run down ( or did you buy it sight unseen). They are probably content with the look of the block. So you can’t expect others to change immediately to suit your agenda (though I agree your agenda is a good one)
Good luck
