Work on the Pontio centre at Bangor University began in 2012 and it opened last year after a delay which cost £1m.
The university said it was also liaising with contractors over concerns about holes in the roof.
But Pontio directors said they had a successful first 12 months and they were confident they could build on their experiences.
They told the Newyddion 9 programme ticket sales for their first year saw about 35,000 sold for live performances, 39,000 for its cinema and about 2,500 for conferences and other events.
A £50m arts and innovation centre in Gwynedd has sold more than 76,000 tickets in its first year.
