The number of new homes built in the first quarter of this year rose by 23.2%, the latest figures from the Central Statistics Office show.
The CSO said a total of 4,275 new dwellings were finished in the first three months of the year, compared with 3,470 completions the same time last year.
Today's figures show that once-off builds increased by 13.1% - from 971 to 1,098 - in the first quarter on an annual basis.
The number of scheme homes rose from 2,023 to 2,564, an increase of 26.7%, while the number of completed apartments jumped by 28.8% to 613 compared to the first quarter of 2018.
The CSO noted that homes in schemes made up 60% of all new completions in the first quarter of the year, while 25.7% were single dwellings and 14.3% were apartments.
The CSO said the main data source for these statistics is the ESB Networks' new domestic connections figures.
However it is accepted these figures overestimate the number of new homes and the CSO has adjusted for this overcount by using additional information from the ESB and other data sources.
The number of new home completions was highest in Dublin at 1,488 followed by 1,072 in the Mid-East.
Together, Dublin and Mid-East made up 60% of all housing completions in the three month period.
Outside of Dublin, there were five counties which had 100 or more new scheme dwellings in the three month period - Meath, Kildare, Louth, Wicklow and Cork.
The highest number of once-off builds at a regional level was 190 in the West.
Meanwhile, Dublin saw 487 new apartments completed, making up over three-quarters of all new apartments completed in the first three months of the year.
The CSO also noted that the average new dwelling size fell by 7.6% in the first quarter of 2019 from 2018, but it added that the figure is provisional and will be revised as more homes are completed during the rest of the year.
