Irish house completions more than doubled in October compared to the same time last year, the latest Goodbody BER tracker shows.

Goodbody uses Building Energy Ratings certificates to calculate the number of house completions, while the Department of Housing figures rely on ESB connections, which show higher numbers of completions.

According to Goodbody's calculations, 1,067 new housing units were registered under BER in October, an increase of 110% from the same time last year. 

A total of 7,503 units have been completed so far this year, up 82% on the same time last year.

Goodbody said that other housebuilding indicators, such as those based on electricity connections, suggest a much higher level of output - 13,533 in the year to September.

It noted that 51% of the new homes built in the first ten months of 2017 were in Dublin. 

When the commuter counties of Wicklow, Meath and Kildare are taken into account, Greater Dublin accounted for 72% of new homes completed. 

But Goodbody said that all regions are now experiencing significant housebuilding growth, with new builds in the South-West, for instance, up by 62% in the first ten months of the year. 

Today's index also revealed that 94% of apartments completed so far this year have been in Dublin. 

Goodbody said the 1,139 apartment completions accounted for 30% of the new build in the city. 

Semi-detached homes and terraced houses accounted for a further 30% each. 

Outside Dublin, the most popular type of new home is semi-detached (50%), followed by detached (31%). 

Goodbody economist Dermot O'Leary said that in order to resolve the country's housing shortage, a substantial increase in apartment construction will be required, particularly in urban locations and close to transport networks. 

"This is currently being hampered by high costs of apartment delivery and planning restrictions on densities and heights," he said. 

"It is expected that new regulations on this issue would be published prior to Christmas, but there have been no further updates from the Department of Housing yet," he added.
