The CSO warned caution should be exercised in extrapolating long-term trends on the basis of a single quarter’s data as numbers can vary significantly if a large development or a number of large developments are approved within the same reference quarter.
While there was a 3.2 per cent decrease in the number of one-off houses receiving planning permission, the fall-off eased from the 4.5 per cent annual fall recorded in the first quarter.
There was an increase of 7.3 per cent in the number of individual planning permissions granted for all developments with 7,058 permissions approved compared with 6,575 last year.
