What's the planning story of this house?
When it was built, and the rules since
Most homes here were built 1981–90, after planning permission began and before building regulations (1992).
Each line is a rule that applies to work done after it.

Zoning, protection, tax and flood: the detail
What it says
RES: To protect and/or improve residential amenity
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.
