What's the planning story of this house?
When it was built, and the rules since
Most homes here were built 1971–80, after planning permission began and before building regulations (1992).
Each line is a rule that applies to work done after it.

How we work this out
'On this site' means the record's own map outline touches the registered parcel (or a 12 m circle round the point where there is no parcel). Only the council's own list confirms a protected building; ask the council if in doubt. The OPW flood map's licence lets us show a yes/no only.

How we work this out
Applications whose site outline (or map point) falls on this property. 'No sign building has started' means we found no notice to the council's building control office; small jobs don't always file one, so ask. A missing completion certificate is not proof of a problem: an owner can opt out of official sign-off for a house or extension built for themselves.

Could you extend?
This site is in a conservation area: changes visible from the street usually need permission.
What happened to applications like yours
Extensions are almost always approved here: 88–94% by type. A new house in a garden is harder: 43% approved, and 1 in 3 is asked for more information.

How we work this out
Home extensions are read from the application's description (extension, attic or dormer, porch, garage conversion, garden room), so a few may be missed or mislabelled. The kind is the first that fits: a dormer with a rear extension counts as a dormer. Refusal reasons come from An Coimisiún Pleanála's inspector reports, so they exist only where the refusal was appealed (Dún Laoghaire-Rathdown so far). The council's own reasons are on its planning file.

How we work this out
Homes approved counts schemes of 10 or more homes (one-off houses are not included). Homes started counts every home in a notice that building work was starting. The council figure is the middle value across the council's built-up squares of the same area (3.1 km², about a 1 km circle), so half of them saw more and half fewer.
