The NI House Price Map shows not just where homes are most expensive, but where properties command the highest price per square metre.
We have scoured the data to find the nine most exclusive postcode areas within Northern Ireland, with the highest property prices per square metre.
Our list uses the highest figure for a specific postcode within each postcode area.
Even if a postcode area appears numerous times in the list of most expensive specific postcodes, we have only included the highest figure for that postcode area.
We have ranked the areas according to how much more expensive they are per square metre than the Northern Ireland average.
This roughly corresponds to the areas with the most expensive homes, but the average house price is sometimes driven up because there are more large houses in that area.
In one postcode, a typical house costs a staggering £4,149 per square metre more than the Northern Ireland average.
The NI House Price Map takes the 2005 valuations from Land & Property Services to give a more localised breakdown and updates them to reflect modern values using the latest Northern Ireland Statistics and Research Agency (NISRA) Northern Ireland House Price Index.
Values are only calculated for postcodes with at least 10 properties in the LPS data.
Below are the nine postcode areas within Northern Ireland with the highest property prices per square metre, based on figures from the NI House Price Map.
