The Renaissance ROM expansion was a $270 million project that transformed the Royal Ontario Museum into the largest museum in Canada. Its centrepiece, the Michael Lee-Chin Crystal, is a bold addition designed by Studio Daniel Libeskind and realised with B+H Architects as executive architect. Comprising five interlocking, self-supporting prismatic structures clad in champagne-coloured anodised aluminium, the Crystal added 100,000 square feet of new exhibition space, a new entrance and lobby, and three restaurants at street level. Ten galleries in the historic ROM building were also renovated as part of the programme. Trinity Consultants Canada provided acoustic consulting services across the expansion.

The museum’s position at one of downtown Toronto’s most prominent intersections, Bloor Street West and Avenue Road, places it directly above TTC rapid transit infrastructure. Museum Station on Line 1 (Yonge-University) has its main entrance at the museum’s threshold, and the St. George station on Line 2 (Bloor-Danforth) is steps away. Ground-borne vibration from subway operations runs beneath and around the building, presenting a persistent source of potential interference for exhibit environments and visitor experience. Reconciling the acoustic requirements of a world-class museum with the structural and spatial complexity of Libeskind’s unconventional geometry defined the scope of our team’s work.

Vision

The Renaissance ROM expansion set out to redefine the museum as a civic and cultural landmark for Toronto. The ROM had been established in 1912 and had grown through several additions to its heritage Darling and Pearson building, but the $270 million Renaissance ROM project represented the most ambitious transformation in its history. At the heart of the programme was the Michael Lee-Chin Crystal, Studio Daniel Libeskind’s addition of five interlocking prismatic forms that extend from the historic building’s north and west faces along Bloor Street West. Alongside the Crystal’s 100,000 square feet of new exhibition space, a new entrance, lobby, retail, and restaurants, the project also included the renovation of ten galleries within the existing building. Completed in 2007, it established the ROM as the largest museum in Canada and one of the most-visited.

The architectural ambition of the Crystal set the terms for every discipline on the project. Libeskind’s five prismatic structures have no parallel walls and all panels are inclined on one or two planes, producing a building with no conventional acoustic geometry anywhere in its new construction. Exhibition spaces within the Crystal required acoustic environments capable of hosting a wide range of programming, from permanent collections to large-scale travelling exhibitions, while maintaining the quiet, controlled conditions that protect both visitors and the artefacts on display. At the same time, the museum’s location above TTC rapid transit infrastructure meant that ground-borne vibration was a design constraint that had to be addressed from the outset.

Partnership

Our team worked within a design structure led by B+H Architects as executive architect, with Studio Daniel Libeskind as design architect. The Crystal was considered one of the most structurally complex construction projects in North America at the time of its delivery, with Libeskind’s five self-supporting prismatic forms sitting adjacent to but structurally independent of the historic ROM building, connected only by bridges linking the two. That structural independence had acoustic implications: the behaviour of the Crystal’s own structure with respect to vibration transmission differed from the existing masonry building and required assessment on its own terms.

Acoustic input spanned multiple building systems and space types simultaneously. The programme encompassed new gallery spaces within the Crystal, renovated galleries in the historic building, lobby and circulation areas, restaurant and retail spaces at grade, and the museum’s interface with its urban context. Coordinating acoustic recommendations across that range of space types, within a design process driven by an internationally recognised architectural vision, required our team to work closely with B+H Architects to ensure that performance criteria were woven into the design rather than addressed after the fact. The renovation work in the existing building introduced a further layer of coordination, as interventions within the heritage structure required sensitivity to both its existing acoustic conditions and its physical fabric.

Services Performed

Trinity Consultants Canada provided acoustic consulting services for the Renaissance ROM expansion, including vibration isolation design for the Blockbuster Gallery floating floor system, sound isolation and mechanical noise control across new and renovated gallery spaces, interior acoustic treatment recommendations, and assessment of construction-related acoustic and vibration impacts on the existing museum.

Value-Add

The most concentrated area of acoustic work on the project was vibration isolation from the adjacent TTC subway. The Blockbuster Gallery, designed to host the museum’s large-scale travelling exhibitions, sits in close proximity to subway operations and required a level of vibration control commensurate with the sensitivities of the collection and the expectations of a major cultural institution. Our team designed a floating floor system for the gallery, isolating the floor structure from the surrounding building to interrupt the path of ground-borne vibration before it could reach the exhibit environment. The design process involved measurement and analysis of existing vibration conditions to establish appropriate isolation criteria and inform the specification of the floating floor assembly.

Across the gallery programme, acoustic design addressed sound isolation between spaces, mechanical noise control, and interior acoustic treatments appropriate to each space type. Museum galleries present particular acoustic demands: they must be quiet enough to support focused engagement with exhibits, manage the ambient noise generated by visitor activity, and avoid conditions that cause speech to carry intrusively between adjacent spaces. The inclined, non-parallel surfaces of the Crystal’s exhibition volumes introduced acoustic behaviour that required careful analysis, as angled walls and ceilings distribute sound energy differently from conventional rectilinear rooms. Our team developed interior treatment recommendations to support appropriate reverberation conditions within each gallery while remaining compatible with the architectural intent.

The construction phase introduced a further dimension to the acoustic scope. With museum operations continuing in parts of the existing building throughout the project, our team assessed the acoustic impacts of construction activity on occupied areas and provided guidance to help protect the visitor experience during the build. That assessment covered both airborne noise from construction and ground-borne vibration, both of which had the potential to affect galleries and collection storage in the heritage building adjacent to the Crystal’s construction zone.

$270

million project budget

Thanks to Jaffe Holden’s exceptional design, the Institute of Contemporary Art’s Barbara Lee Family Foundation Theater has consistently impressed both audiences and performing artists since opening in 2006. The discrete acoustical treatment above our hardwood ceiling, as well as the rippled design of the theater’s entire East wall, plays a crucial role in managing reflections and ensuring both clarity and warmth. Additionally, the team’s expert noise isolation design allows for seamless co-existence between the Barbara Lee Family Foundation Theater, our lobby, and our galleries, even as significant development has transformed the surrounding Seaport District. Their expertise continues to be invaluable, and we deeply appreciate their ongoing support in maintaining the integrity of their original acoustical vision.
