Question 1

What's the planning story of this house?

Figure 1

When it was built, and the rules since

Most homes here were built 1991–2000, under planning permission and building regulations.

Timeline from 1955: planning permission needed from October 1964, building regulations from June 1992, building records online from March 2014, sign-off opt-out from September 2015.

ZoningR2 · Existing residential
What it says

RS - Residential: Provide for residential development and protect and 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.

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 council's map for the vacant land tax shows this spot inside an area of existing homes. Homes people live in, and their gardens, don't pay the tax. 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.

Question 2

Could you extend?

Nothing on this site restricts it: not protected, not in a conservation area.

Figure 2

What happened to applications like yours

Extensions are almost always approved here: 85–100% by type. A new house in a garden is harder: 65% approved, and 1 in 2 are asked for more information.

Nothing refused this close in the last 12 months.

    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.

    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.
