The Housing Minister says he cannot guarantee that the construction sector will fully reopen from April 5th.
It was hoped that the industry would have been able to resume working fully from today.
However, that did not go ahead, following NPHET's advice to the government.
Construction is allowed to continue in a limited number of circumstances.
Around 800 homes a week are not being built because of the current shutdown.
Meanwhile, just under 60,000 constructions workers have been laid off and are receiving the pandemic unemployment payment.
The Taoiseach has said getting back to home building in April is a priority of the government.
Despite that, Housing Minister Darragh O'Brien says no promises can be made:
He's said "No, there's no guarantees. It will obviously be based on public health advice."
"The NPHET advice that we made our decision on to extend the restrictions was very stark. We're operating with a new variant now".
