The extra information doesn’t change my response, but note I am not familiar with ACT requirements.
In relation to (iv), the owner might benefit from the decision, but the key element of the decision is the actual renovation, not who is doing the renovation, so there is no reason why that party shouldn’t participate in the decision. The financial benefit is a consequence of the primary decision, it is not the primary decision. Note the scheme is not paying for the works to be done.
