The Aberconwy Centre opened to the west of the Arcadia theatre in 1982. The conference venue had space for over 1,000 conference attendees. It also featured squash courts, sun beds and badminton courts.
The Centre was redeveloped in 1994, and it was renamed the North Wales Theatre and Conference Centre. It hosted a 1,500-seat auditorium/theatre, as well as a 700 square metres (7,500 sq ft) conference hall with capacity for 800 seated, or 1,000 standing, people.
In July 2005 the Arcadia theatre was demolished to make way for an atrium and meeting and conference rooms adjoining with the North Wales Theatre and Conference Centre. The building was also extended to the west. After the redevelopment, the venue hosted a new 1,550 square metres (16,700 sq ft) arena, capable of hosting 1,800 seated, or 2,500 standing people, increasing the overall capacity of the venue to over 5,000 people. The western extension incorporated a café, restaurant and a box office, as well as office space.
