Theatr Clwyd reopens after bold £25m transformation into a sustainable arts hub

Haworth Tompkins has completed a major redevelopment of Theatr Clwyd, a Grade II-listed theatre and cultural centre overlooking the town of Mold in North Wales. Originally opened in 1976 as the Clwyd Theatre and Educational Technology Centre, the building was conceived as a multi-purpose regional arts venue, combining performance spaces with studios, galleries and community facilities. Nearly fifty years on, the practice's intervention reframes the sprawling 10,000 square metre complex as a more coherent, accessible and technically capable civic destination, while retaining the character of the original structure.

Set into a hillside with expansive views across the Clwydian landscape, the building has always held a strong relationship with its surroundings. Haworth Tompkins' redesign looks to strengthen this connection through the addition of a new three-storey glazed foyer on the south-west elevation. Organised around a central atrium, the extension forms a clear and welcoming entrance, replacing previously fragmented points of access. Inside, a sequence of light-filled public spaces incorporates a café, restaurant and informal working areas, conceived as a covered public square that extends the building's use beyond performance times.

The project addresses the limitations of the original plan, where circulation routes had become convoluted and restrictive. A new internal 'street' now runs through the building, linking auditoria, gallery spaces and public amenities in a more legible arrangement. Alongside its three performance venues, cinema and event spaces, the theatre now accommodates rehearsal rooms, studios, workshops and dedicated areas for community use. Back-of-house facilities have been significantly improved, supporting a more integrated approach to theatre-making, including a new scenic workshop that allows production teams to work together on site for the first time.

A key aspect of the work carried out is an emphasis on improved access and inclusivity. Step-free routes have been introduced across all levels, supported by new lifts and enhanced auditorium layouts that provide additional wheelchair seating. A Changing Places facility, sensory gardens and play areas extend the building's role as a civic resource, broadening its appeal to audiences of different ages and abilities.

Rather than pursuing wholesale replacement, the scheme adopts a deep retrofit strategy, retaining much of the existing concrete frame and envelope. This approach minimises embodied carbon while enabling significant upgrades to environmental performance. Improvements to the building fabric are combined with passive design measures, upgraded services and the replacement of gas boilers with air source heat pumps. On-site photovoltaics and a renewable energy tariff further contribute to operational decarbonisation.

The redevelopment has been shaped by extensive consultation, with more than 22,000 responses informing priorities around accessibility, sustainability and community use. Delivered through a phased construction programme, the works allowed the theatre to remain operational throughout, maintaining its role as a cultural anchor for the region.
