Dublin will need €70 billion invested in the likes of housing, transport and climate risk over the next 15 years.
That's according to KPMG, which has surveyed hundreds of businesses to evaluate the city as a place to live, work and do business.
The company's Dublin 2040 report has infrastructure, including affordable housing, as the most important area for improvement in the capital, at 24 per cent.
60 per cent of businesses cited housing as the biggest challenge. While the survey found urban appeal, education and training were rated among the other priority areas for improvement.
A key recommendation in the report is to treat housing and real estate investment partners similar to long-term foreign direct investment.
