The opening of phase two of the Blanchardstown Centre before the end of the year is expected to lead to the creation of 500 retailing jobs.
The developers, Green Property, are investing £20 million in the 190,000 square feet retail park which includes reserved space for 14 domestic and international retailers.
The Irish Times understands that among the retailers taking space are Clerys, Atlantic Homecare, Courts, the furniture company, Staunton Sports and Tully Tiles.
Atlantic Homecare is taking a 40,000 square feet site, which is the largest of phase two. One other large DIY retailer is expected to move into the centre, in what is described as a "major contract". A large food retailer is not expected to take space at the centre.
A separate building adjoining the phase two section will include a 30,000 square feet pub and leisure complex.
The pub will be operated by Mr Hugh Regan, the owner of the Harbourmaster bar in the IFSC, and the leisure complex will include a Paddy Power bookmaker, a restaurant, an off-licence and a Blockbuster video store.
Some 1,400 additional car parking spaces will be provided, bringing to 5,300 the total number of car spaces available. There are currently 2,500 people employed at the centre, where the anchor tenants are Dunnes Stores and Roches Stores. Other developments are currently being added to the existing centre. These include a medicentre, two post offices and a credit union. There are further plans to build an art centre and a library.
"About 50 per cent of the people working in the centre live within a three miles radius of the centre and I am hopeful that many of the additional 500 jobs will be secured by local people," said Mr Aidan Grimes, the manager of the Blanchardstown Centre.
He added that, with 3,000 people working in the centre, it will become one of the largest employers in the country. He said the area is one of the fastest growing areas of Co Dublin and is easily able to support a development of this size.
The new Liffey Valley shopping centre, due to open in October, will compete directly with the Blanchardstown Centre.
