AIB and Ballymore have agreed the refinancing of over €130m through a five-year green loan facility.
The funding will be used to accelerate Ballymore's nationwide housing pipeline, leading to the construction of some 2,000 new homes in Ireland, with potential for a further 2,000.
Ballymore is currently building 1,500 homes on nine sites in Bray, Mullingar, Naas, Newbridge, Portmarnock and Rush.
Completed developments supported with AIB financing include Dublin Landings (a commercial and residential at North Wall Quay), Seamount Rise in Malahide, multiple sites in Co Kildare including River Walk in Ballymore Eustace, Bellingsfield, Piper's Hill and Longstone in Naas and Station Walk in Newbridge, and Sea Gardens in Bray.
Ballymore said it is progressing a major new scheme in partnership with the Land Development Agency in Balbriggan, in North Co Dublin.
As part of wider national efforts to tackle Ireland's housing shortage, the development is set to deliver over 800 homes alongside new infrastructure and community amenities.
AIB is the largest lender to the home building sector in Ireland and approved over €1 billion for residential development, supporting the construction of between 9,000 and 10,000 new residential units last year.
AIB noted that lending to energy efficient homes amounted to 59% of all new mortgages issued by the bank in the first nine months of 2025, while green lending to commercial real estate made up 73% of total lending to the sector in the first six months.
AIB's chief executive Colin Hunt said that Ballymore is a trusted partner of AIB, and the two companies share a strategic priority in delivering thousands of homes to communities throughout Ireland.
"Our track record with Ballymore is strong, and this new facility is our commitment to continue financing new A-graded sustainable homes," Mr Hunt said.
"By working together AIB and Ballymore are part of the housing solution. Our appetite for lending to house builders remains strong and we are keen to increase our funding for the residential market in the coming years," he added.
Ballymore CEO Sean Mulryan said the company's relationship with AIB has been built on shared values and a mutual commitment to delivering high-quality, sustainable homes across Ireland.
"This green loan refinancing gives us the certainty and flexibility to accelerate construction on key sites nationwide, ensuring we continue to meet housing demand with the design excellence and long-term vision that define Ballymore," he said.
"It also reflects our continued investment in Irish communities and our ambition to shape the future of housing through innovation, sustainability and community building," he added.
