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 1971–80, after planning permission began and before building regulations (1992).

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. Most homes here were built 1971–1980.1960197019801990200020102020Oct 1964permission neededJun 1992building regulationsMar 2014building records onlineSep 2015owners may opt out of sign-offThis houseBuilt: most homes in this small area date from 1971–1980 (census estimate)most built

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 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.

Could you extend?

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

Refused within 100 m 0 in the last 12 months

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.

    What happens to applications within 500 m

    Permission isn't building. Of 82 permissions since 2016, 39 show a start notice and 2 have a completion certificate. Most owners opt out of sign-off.

    98 applications lodged within 500 m. Council: 83 approved, 4 refused. After appeals: 82 approved. Of those: 2 signed off, 25 built with the owner's opt-out, 12 started, 41 with no start notice found, 2 ran out.LODGEDCOUNCIL DECISIONAFTER APPEALSWHAT HAPPENED NEXT83: lodged → approved4: lodged → refused10: lodged → withdrawn or invalid1: lodged → undecided81: approved → approved3: refused → refused10: withdrawn or invalid → withdrawn1: undecided → undecided1 approved by the council, undecided after an appeal1 approved by the council, withdrawn or invalid after an appeal1 refused by the council, approved after an appeal41: approved → no start notice found25: approved → built, owner opted out12: approved → started, not signed off2: approved → signed off2: approved → ran out98 lodged98 lodged83 approved83 approved4 refused4 refused10 withdrawn or invalid10 withdrawn or invalid1 undecided1 undecided82 approved82 approved3 refused3 refused11 withdrawn11 withdrawn2 undecided2 undecided41 no start notice found41 no start notice found25 built, owner opted out25 built, owner opted out12 started, not signed off12 started, not signed off2 signed off2 signed off2 ran out2 ran 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.
