How prices are measured on this page
Typical price is the median: half the sales were above it and half below. Average price is the mean, which a few very high or very low sales can pull up or down. They are two measures of the same sales, so they are expected to differ.

Transport, broadband and zoning
Public transport stops inside the Dalkey boundary, ComReg's fixed broadband coverage for its Small Areas, and how the current development plan zones the land.
- Rail and DART
- Dalkey
- Stop density
- 25 stops across 3.48 km², about 7 per km². Bus stops are counted per pole, so a road served in both directions counts twice.
Broadband figures are ComReg's averages across the 30 Small Areas that make up Dalkey: 90% of premises passed by a gigabit network and 66% connected. They describe the area, never one address.
Land use. 68% of the zoned land is residential under the current development plan, 2022 to 2028, 298 hectares in all.
| Zone | Description | Hectares | Share |
|---|---|---|---|
| R2 | Existing residential | 204 | 68% |
| G1 | Open space, park | 65 | 22% |
| S5 | Mixed/general community services/facilities uses | 15.4 | 5% |
| G3 | Conservation, amenity or buffer space, corridor/belt, landscape | 8.8 | 3% |
