Work on the new €50m Kildare Village expansion, which is set to bring 500 jobs, is due to begin late next year.
The plans, which will see the retail outlet almost double its size, are expected to yield 190 full time and 190 part time jobs, as well as 120 construction posts.
The extension will also result in an extra €5.5m being injected into the economy in wages.
Kildare Village was granted planning permission by An Bord Pleanala last week for the extension.
It was initially granted permission by Kildare County Council last year, but the decision was appealed by Whitewater Shopping Centre.
Speaking on Friday, Maria McGovern, Director of Kildare Village, said; “The new development will generate significant employment opportunities, and the international investment in the region will give the necessary critical mass to enhance the overall experience of Kildare Village, making it an even more attractive shopping destination for national and international tourist visitors to the town and surrounding areas”.
The expansion will enable Kildare Village to increase the number of boutiques by 36.
First opened in July 2007, it is currently home to more than 60 stores and employs 550 people.
In a statement the company said; “The significant expansion of Kildare Village will not only enhance the tourism offering of County Kildare and its surrounding areas but will enable Ireland compete with best international tourist outlet destinations.”
Kildare Chamber president, Brian Flanagan stressed; “We are delighted. We supported the expansion from the very outset.
“Obviously we are thrilled with the number of jobs that will be created. The sooner the work starts, the better.”
Local TD Sean O’Fearghail commented; “This is fantastic news for Kildare.
“I know it has been a particularly long and difficult process to secure permission for this expansion and great credit must go to the management who have perused the plans vigorously.”
Deputy Martin Heydon emphasised Kildare Village makes a huge contribution to the local economy, adding that 80% of the visitors to the facility come from outside the county, with 15% from overseas.
At an oral hearing in April, Whitewater Shopping Centre argued the extension would impact greatly on its business. The Village refuted this.
The development will earn Kildare County Council a once-off development levy payment of €650,000 as well as €240,000 in annual rates.
