Zoning evaluated against the point

Objective A: A To provide residential development and improve residential amenity while protecting the existing residential amenities

What that means: An established residential area. The objective is to protect existing residential amenity as well as to provide housing — which is the objective a neighbour's objection to an overbearing extension is usually argued under.
