RES: To protect and/or improve residential amenity
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.

`description` is truncated at source (80 chars for DLR, 70 for Fingal) and `applicant` is null nationally — NPAD publishes neither in full.
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`).
Third-party advertisement data captured by Cara from daft.ie. Not open data: internal analysis only, no redistribution of listing content.

No publishable utility-capacity record within the radius. 10 records from Esb substation withheld: source licence forbids redistribution; see the operator's own register.
