South Dublin County Council has granted Basketball Ireland planning permission for a €38m redevelopment of the National Basketball Arena in Tallaght.
The project will see the multi-sport and multi-use arena double its capacity to 3,272, with works expected to take 18 months to complete.
The 8,000 square metre facility will have space for four basketball courts, a gym, cafe, corporate facilities and office space for Basketball Ireland staff.
The arena will be fully accessible and inclusive and has the backing of a number of sporting bodies, including Volleyball Ireland, Badminton Ireland and Irish Squash, who all wish to use it.
Basketball Ireland CEO John Feehan, said: "This is excellent news and a major step forward in bringing the new National Basketball Arena to fruition.
"The arena will be transformative for Irish indoor sport, providing state-of-the-art facilities that will be on a par with our European counterparts."
