A 350-seat theatre for Rendcomb College, structurally engineered to sit sensitively within the Cotswold landscape using retaining walls, concealed steelwork and cantilevered entrance spaces.
Rendcomb College Performing Arts Centre: Structural Engineering for a Cotswold Theatre Building
The Performing Arts Centre at Rendcomb College presented a challenge that went beyond simply creating a theatre. Our task as structural engineers was to help integrate a modern performance venue into one of the most sensitive landscapes in the Cotswolds, respecting adjacent listed buildings and the surrounding countryside throughout.
Overview: Structural Engineering for a Sensitive Cotswold Setting
The Performing Arts Centre provides a 350-seat auditorium together with rehearsal, teaching and support facilities. As experienced structural engineers, we worked closely with the design team to position the building so it would respect its neighbours rather than dominate them.
Rather than sitting above ground, the auditorium was partially set into the ground, while ancillary accommodation was built into the natural slope of the site. A sedum roof further reduced the building's visual impact and helped it sit comfortably within the surrounding landscape.
The Challenge: Integrating a Modern Theatre into a Historic Landscape
Designing a large performance venue within this setting called for a structural approach that supported the architecture without overwhelming it. The building needed to provide a full-scale auditorium, technical spaces and support facilities, all while remaining sensitive to nearby listed buildings and the wider Cotswold landscape.
The design also needed to conceal a significant amount of technical infrastructure. Theatre walkways, access routes and lighting equipment all required accommodating within the roof space, while keeping the performance areas below clear, flexible and free from unnecessary structure.
The Solution: Reinforced Concrete, Steel Trusses and Cantilevered Entrance Spaces
Structurally, the building combines reinforced concrete retaining walls, a primary steel frame and exposed timber flitch beams. This combination of materials allowed the building to respond to the sloping site while giving the design team the flexibility to create a distinctive, sensitively scaled structure.
Concealed Steelwork Supporting the Auditorium Roof
Large steel trusses spanning above the auditorium support theatre walkways, access routes and technical lighting equipment hidden within the roof space. This allowed the performance areas below to remain clear and adaptable, without visible structure interrupting the space.
Cantilevered Entrance Spaces
The entrance spaces make use of cantilevered structural elements to minimise internal columns, creating a more open and welcoming environment for visitors as they arrive. Externally, locally sourced stone, timber and glazing were selected to complement the wider character of the Cotswold landscape.
