The former Waterford Crystal offices and showrooms on the Cork Road in Waterford are to be totally refurbished.
Ibrook Ltd has received planning permission from Waterford Council to carry out the work.
The three-story office block will have the cladding and glazing replaced and will be extended by 920 square metres.
A food court and retail unit will be provided in a section of the former showrooms.
The old single-storey restaurant on the site will be demolished.
Noel Frisby told WLR News that he was thankful to the planners who dealt with the matter speedily and which now allows a major facelift to take place.
The plant ceased operating in January of 2009 and the 36-acre site was bought by Noel Frisby in 2013.
He spent close to €500,000 between 2013 and 2017 getting the site ready for redevelopment.
Noel Frisby said the centre has been the subject of major vandalism in recent months.
He said that in doing this development on spec he hopes the state bodies will do their job in attracting new companies into the area and creating new jobs.
Mr Frisby envisages the building will be used for IT companies, the restaurant will be open to the public with up to 700 people working in the building.
