€340 million worth of loans to builders and developers were approved by the State-backed lender in a six-month period up to July.
Home Building Finance Ireland - which was established in 2018 to provide funding for commercially viable residential developments - says that's three times the value of loans from the same period last year.
Finance for 1,477 new homes in 29 developments across 16 counties were approved.
A €200 million COVID Momentum Fund was established as building resumed after the lockdown, and that has now been topped up by an additional €100 million.
Finance Minister Paschal Donohoe says funding for projects would likely to have been delayed due to COVID-19 without the fund, so it's 'appropriate' to top it up now to ensure funding continues to be available.
HBFI Chief Executive Dara Deering told Breakfast Business there's been 'strong interest' in the finance they've been offering.
She said: "There has been and continues to be commercially viable schemes where finance is a challenge - we anticipated that may be further constrained post COVID-19, hence we were flexible and adapted our offering accordingly.
"Most of the schemes we're supporting this year will come to market at the end of 2021 or into 2022.
"That's why we were very keen to ensure - notwithstanding the challenges that COVID-19 brought to all of us - that there wouldn't be a short-term impact in supply, which could have a longer-term impact."
Ms Deering said HBFI is confident they'll be able to continue to help to finance projects into the future.
She observed: "The initial fund we had was given from the Ireland Strategic Investment Fund, but under our legislation we also have the ability to borrow another €750 million of funding if required from the markets in general.
"If you look at the nature of our business, we lend our money for the construction phase - which is a about a two-year period - and then that money is paid back. We can also recycle that money over the next number of years. We've very confident we will have a sufficient level of finance."
