Yeah, I remarked in some of my earlier price/sq.ft. analyses that you pay a massive premium for 4-beds in Dublin. They’re even more expensive than 3-beds when measured by the sq.ft., whereas in the rest of the country you seem to get more economy of scale with prices per sq.ft. going down as you go to bigger houses.
On a broader note, looking at the 3- and 4-bed graphs, I can quite understand the “everything is up by €100k” anecdotes. If you were comparing, say, October last year with some of the prices around the turn of the year, to pull the averages up must have taken some pretty hefty individual increases. Added to that, people’s anecdotes are always going to reflect the most bubbly prices, since they’re the most memorable. Whether those increases can be sustained – or are even being sustained now – is questionable given the way the data for this year is bouncing around. I wouldn’t be brave enough to make any predictions though (especially about the future )
