The Mezzanine Room at Belconnen Library is a bookable community room for up to 50 people, according to Libraries ACT. The current room-hire directory confirms kitchen facilities, but does not publish a dedicated audiovisual equipment list or private-event inclusions for this specific room. It is best treated as a municipal library venue for meetings, information sessions and community workshops, with any out-of-hours access and catering arrangements agreed when booking.
