The housing crisis has been likened to Garth Brooks concerts by the former chair of The Land Development Agency.
It comes after The Housing Agency CEO Bob Jordan said homeowners have to accept that their house values will fall as supply increases.
He also encouraged older people to downsize to make larger homes available for younger families.
John Moran, Former Chair of the Land Development Agency, told Newstalk Breakfast prices must come down - but we can't let them crash.
"It's very simple: we have too few houses for too few people... and so house prices do need to fall," he said.
"But we can't let then fall dramatically like has happened 10 or 12 years ago, because house prices effectively are also an anchor to the economy.
"If they fall too quickly, we'll lose confidence, we'll lose jobs and we end up in a situation where we've got low house prices but actually we've got much bigger problems on our hands."
Mr Moran said the situation is similar to "Garth Brooks tickets".
"We have a stadium, which is our infrastructure and is a certain size," he said.
"Garth Brooks cannot play many concerts at the same time, so we have to stretch him out over the course of the week.
"But if we actually only have one concert on a Saturday night, the people who have the most money will pay the most money for those tickets.
"So, essentially we have to have a credible plan to convince Garth to play enough concerts over a course of time that everybody believes they can get to one or two concerts - whatever they can afford.
"That means, once we know that Garth is coming on enough nights, people that would have paid an awful lot of money for the first night stop wanting to do that because they figure they wait until Thursday night.
"All of a sudden, prices start to go down as these concerts are announced".
Mr Moran said there needs to be a geographical spread of the concerts too, in Cork and Galway, "so people wouldn't actually have to go up to Dublin."
"That means that the price of the tickets and demand for the concerts in Dublin also goes down."
Mr Moran said the problem is that the Government's Housing for All targets have been based on "the assumption that they could only convince Garth to do three concerts, not that they would make him do six".
Fine Gael housing spokesperson John Cummins said there needs to be many broad changes.
"You'll see in the round [Bob Jordan] was commenting broadly on a number of areas that he felt would help to increase supply," he said.
"He spoke about intergenerational solidarity in terms of reducing the objections to housing and right-sizing options for people.
"The article was broadly in terms of increasing supply and I would agree with him on that.
"I think it will certainly help moderate house prices and the Government is doing that.
"We've seen record completions last year; our commencements are up, there's 500 first-time buyers now every single week that are purchasing their first home," he added.
Figures last year showed home completions were at the highest rate in over a decade.
