Zoning evaluated against the point

R2 — Existing residential county development plan 2022 2028 · 1 Apr 2022 – 1 Apr 2028

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.

PPR addresses are geocoded, not surveyed — a sale's position is as good as its address match (`rooftop_n` says how many are address-accurate). Beds, floor area, BER and asking price come from the matched daft.ie advertisement, not from the Register, and only where a match was found (`enriched_n`).
