“The once-in-a-generation transformation is complete”, reads the website of the iconic Bristol Beacon performance venue in Bristol, England. Designed by Levitt Bernstein Architects with local support from Alec French Architects, the reopened venue features more than a new name. New facilities include an improved Lantern Hall, a new restaurant, and spaces put into use for the very first time.
Acoustics were immediately set as a priority by all stakeholders and Levitt Bernstein’s interior configurations were largely centralised around an even distribution of sound. “The Bristol Beacon will have world-class acoustics and be one of Europe’s premier music venues”, said Chris Townsend, Senior Design Manager at Willmott Dixon Construction, the main contractor on the project. “Acoustic design and the selection of the correct absorbing and reflecting products that could respond to these exacting requirements was essential, with every layer and nuance needing careful consideration”.
Planning the Concert Hall’s Renovation
Formerly called the Colston Hall, Bristol Beacon was constructed in 1867 and stands out for its Neo-Byzantine architecture, commonly known as Bristol Byzantine due to its prevalence in the city during the late 1800s. Hosting iconic artists like Nick Cave, Iggy Pop, and Joy Division over the years, it now features a new tribute staircase honouring these legends.
Renovation has long been discussed, and in 2009, Levitt Bernstein completed the first phase – a new foyer. The second phase was much more extensive and would involve its primary performance hall, a venue with Victorian details known as the Lantern Hall. The Arts Council contributed 22 MGBP in capital funding toward its renovation, marking their largest investment over the past ten years. In total, the Bristol Beacon’s makeover represents an expenditure of 132 MGBP.
According to the Bristol Beacon, the renovation aims to help the theatre in hosting 200 more concerts annually, offering educational opportunities to an additional 10 000 children and young people, and advocating for greater diversity in the music scene.
Sustainability was also key consideration. As part of the renovation, a committee established a roadmap to become the UK’s first net zero concert hall by 2030. Aligned with three of the United Nations Sustainable Development Goals, the roadmap covers initiatives including green electricity and biogas, zero waste efforts, and a decarbonised supply chain.
The venue was scheduled to re-open in 2020, but both Brexit and the pandemic presented significant challenges, particularly in terms of material availability – which is when Rockfon rose to the challenge by offering the alternative acoustic systems required for key performance areas.
Acoustic Solutions for the Concert Hall Design
Levitt Bernstein Architects and acousticians Sound Space Vision designed and specified a solution that met the high quality and acoustical attributes, carefully balanced with some stringent conservation commitments.
“In the reimagined Lantern Hall, the original 1800s theatre, over 250m² of Rockfon Eclipse Acoustic Islands were installed to achieve the absorption requirements for this versatile space which can accommodate a standing audience of 350”, said Townsend. Rockfon Eclipse acoustic ceiling islands were identified as solutions that could meet all the essential performance criteria, including fire resistance and test certification.
The brick-vaulted “Cellars” were previously used as a storage basement. To ensure comfortable reuse and prepare them for their new function as performance venues, over 108m² of Rockfon VertiQ panels were also installed within the crowns of the vaults.
Rockfon collaborated extensively with Korbuild and other members of the design team to ensure the realisation, and possibly the surpassing, of the project's goals. They focused on developing a sophisticated and unobtrusive support grid that harmonised with the historical roof truss layout. Rockfon also closely collaborated with installers and designers to ensure that head heights were not compromised and that the intricate network of mechanical and electrical services could be seamlessly integrated.
"This was a very rewarding, high-profile project we’re proud to play a part in. The acoustic requirements, listed building status, historic and elaborate architecture and ceiling configuration provided challenges which, due to the versatility of our specialist acoustic systems, we’re able to meet”, said Rockfon Specification Manager, Rowan Green.
“We’re delighted to have had the opportunity to collaborate with Rockfon on the Bristol Beacon project. Its successful execution was made possible through the collective efforts, dedication, and effective communication between all involved. We are confident that the outcome will bring lasting value to the Bristol Beacon and the surrounding area”, concluded Korbuild Operations Director Neil Evans.
