Newry headquartered Murdock Builders Merchants has bought Brooks Group, which includes Brooks Builders Merchants and Dublin Plywood and Veneer, from Welsh based Premier Forest Products Group.
Murdocks has 10 branches and two timber processing facilities in Northern Ireland as well as four merchanting outlets in the Republic of Ireland.
Brooks has seven builders' merchants branches in the Republic and DPV has its timber distribution based in Dublin.
Today's deal is subject to the approval of the Competition and Consumer Protection Commission.
Ciaran Murdock of Murdocks said that since establishing the business in 1982, it has gradually built up the business by opening new branches along with some single site acquisitions.
"Today's announcement marks an important strategic move in significantly broadening our footprint in the Republic through the Brooks business.
"We believe that this provides us with a great platform for further expansion in Ireland," Ciaran Murdoch said.
"It is also notable that Brooks, which was originally established in 1750 and has a long and storied heritage in timber provision and in merchanting in Ireland, returns to Irish ownership for the first time since 1981," he said.
"We very much look forward to working with our new colleagues and the Brooks management team who have done such a good job in growing the business over the past number of years," he added.
Murdocks also said today that after completion of the acquisition, it plans to appoint Eddie Kelly as Chairman of Brooks Group.
Mr Kelly has had a significant career in Irish builders merchanting and as CEO, led Grafton's Merchanting business in Ireland for seven years prior to his recent retirement.
Paul Lynch, a former executive director at Heiton Group and CFO of Applegreen, will also join the board as a non-executive director following completion.
