Zoning, protection, tax and flood: the detail
What it says
Existing Residential: To protect and improve the amenity and character of existing residential areas.
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.
