Councillors meet today to discuss the latest Dublin City Development Plan
There are fears plans to cap Dublin building heights will worsen the city's housing crisis.
The Dublin Chamber of Commerce claims the crisis will be "greatly exacerbated and economic growth stifled" if Dublin city councillors vote to reduce maximum building heights.
The chamber adds that, if anything, density and height need to increase if the capital's population is to be accommodated.
It issued the warning as councillors prepare to meet this week to discuss the latest Dublin City Development Plan.
The chamber has called on councillors to reject any attempts to reduce the maximum building height in the city centre.
As it stands, the draft City Development Plan recommends a maximum building height in the city centre of 28 metres for commercial use, which allows for developments of up to seven storeys.
The chamber says any reduction in height limits would increase congestion, urban sprawl and risk jobs being lost to Dublin's competitor cities across Europe.
According to Aebhric McGibney, director of public affairs and international, at Dublin Chamber of Commerce: "Ensuring growth goes up instead of sprawling ever outwards will provide more space for people to live, make public transport a more viable option for commuters and prepare Dublin for 21st century city living".
"In addition, Dublin must prepare for more people living and working in Dublin".
It says that within 15 years it is likely that more than 2.2 million people will be living in the Dublin region - 400,000 more than currently.
Green Party councillor for Dublin, Ciarán Cuffe, told Newstalk Breakfast there are areas for high-rise - but not everywhere.
While Aebhric McGibney says this is about more than just housing.
