Hotels group Dalata expects to add around 300 Irish jobs this year on foot of opening three new hotels.
Deputy chief executive Stephen McNally told the Sunday Independent that the company aims to open two properties in Dublin and one in Cork by the end of 2018.
But he warned that difficulties in getting extra storeys through planning meant build costs per room were higher, making it more challenging to tackle the capital's hotel room shortage and making banks "more nervous" about financing hotel projects.
"We're opening a hotel on Kevin Street in Dublin and we would have built six storeys instead of four... that would help to solve the capacity problem," McNally said.
Dalata - Ireland's largest hotels group which owns the Maldron and Clayton brands - told investors last month that the supply shortage is likely to continue for a number of years.
Of 2,500 rooms projected by Savills to open in 2019, Dalata said just 1,100 are under construction.
"Increase in supply [is] expected to be matched by increase in demand from continued economic growth, increased visitor numbers and growing evidence of office relocations from London to Dublin," the company said.
