The 1970s-built complex in Mold is in need of a major revamp with a risk to future shows if nothing is done.

Under the £33m upgrade plan, the 45-year-old building will be extensively refurbished and repaired, along with significant improvements to deliver a more energy-efficient building.

This will bring large savings on gas, electricity, and water costs, and make better use of resources.

The thermal envelope of the building will be improved, and renewable energy sources including PV panels and air source heat pumps installed to improve energy consumption. All services and theatre equipment will be replaced throughout the building.

A new timber extension at the front of the building will provide a new, welcoming foyer space at three floors and contains a new double height restaurant, bar and café, as well as a meeting room and Green Room.

Largely glazed, the foyer provides improved views out over the landscape of the surrounding hills, and is shaded by a large timber canopy to the south side.

Two new rehearsal rooms will be constructed, including a full-height room that can take a rehearsal for the Anthony Hopkins Theatre stage, the Clwyd Room will be refurbished with the floor raised to all one level.

Auditoriums are improved technically, with minor improvements to seating planning and control rooms.
