The Fingal area of North Dublin is reporting an upsurge in construction activity with 72 active construction sites across the county - a 50% increase on last year.
In total, Fingal has planning permission for nearly 18,000 units.
Margaret Geraghty, director of housing with Fingal County Council, said that with a large amount of land banks, and its position near Dublin Airport, the M50 and the Dublin-Belfast rail line, the council has ambitous targets for home building.
It also provided 2,200 units of social housing between 2015 and 2017, which was 62% above the Government target.
The Hansfield SDZ (strategic development zone) near Clonsilla will provide 3,000 housing units.
Gannon Homes alone has plans for 3,700 homes across three sites near Swords and on Malahide Road.
The company's commercial director Shane Daly said the time lag in completions coming on the market is the result of planning requirements, infrastructure development, and anticipating the type of consumer demand.
Karl Deeter of Irish Mortgage Brokers said there is a lot of construction going on but houses are still coming on the market too slowly to affect house prices.
He said other Dublin local authority areas are not building as much as Fingal, often due to local opposition to new developments.
