Wimbledon No.1 Court Roof



Thornton Tomasetti provided structural and façade engineering for the redevelopment of the No.1 Court at The All England Lawn Tennis Club in Wimbledon. The project added a new roof with fixed and moveable components; increased seating capacity by 900 seats on two new tiers; created a new two-level public plaza; and upgraded seats, concessions and catering areas, and hospitality facilities throughout the court.

Our structural engineers designed the fixed roof, the long-span trusses of the moveable roof, and structural modifications to the existing superstructure to support all aspects of the redevelopment. The structural design required integration of several important factors. The fixed roof must support the retractable roof components while letting in enough sunlight for the court’s grass, clear sight lines must be maintained and the design must conform to strict planning height restrictions. Fitting new structural elements into the tight space defined by the new building envelope and accommodating a very constrained construction site added complexity to the engineers’ task.

The cladding design features a combination of new vertical façade zones for the hospitality extensions, debentures and cores. New cladding for the roof and bowl areas was designed to complement the geometrical aspects of the Court. Generative modelling was also critical to developing the façade design within spatial constraints and coordinating with other disciplines.

Effective coordination was a key factor in the project’s intricate design. Integrating the retractable roof as well as extensive mechanical and electrical equipment into the fixed roof structure required careful design and coordination with the moveable roof consultants. Spatial constraints required active collaboration and advanced technology to avoid clashes and meet the project’s aesthetic and functional requirements.

Façade Materials & Systems


Composite materials – fiber reinforced plastics (FRP), glass fiber reinforced concrete (GFRC) and polycarbonate – make for elegant, lightweight and cost-effective enclosures. These materials are well-suited for use in stadiums and long-span buildings, both in new construction and for re-roofing existing structures. Most composites adapt to nearly any complex shape and are available in an array of thicknesses and finish options, from translucent to opaque. Using our 3D form-finding and optimization tools, we can adapt commercial systems or develop customized solutions.

Glazing & Structural Glass

Glazing offers transparency that enhances a façade’s aesthetics and experience from both the interior and exterior. It provides light and a visual connection between the inside and outside. But designing with glass requires the deliberate balancing of light transmittance and the effects it has on energy performance and occupant comfort. Glazing design also requires careful consideration of material strength and safety. We provide a full range of design and engineering support for glazing and glass structures, from structural analyses to recommendations for aesthetics and energy performance. Our expertise in glazed-façade and structural-glass construction includes unitized aluminum frames, stick-built metal frames, steel cable supports, structural glass fin supports and glass stairs and balustrades.

Façade Materials & Systems


Operable systems provide flexibility of use of a space, increase energy performance and enhance occupant comfort. Ranging from retractable roofs to operable screens on a façade, they can open or enclose a space and increase or decrease sun exposure. Some are automatic; others rely on manual control. Many can be incorporated into other façade systems. Our engineers work with designers to create custom solutions for building envelopes that satisfy performance requirements while giving owners the visual and experiential effects they desire.

Façade Materials & Systems


A variety of metals are used to wrap a building’s skin: aluminum, stainless steel, copper and zinc are notable examples. Each has its own special characteristics and can be used as rainscreen cladding, open screens, overhead enclosures or decorative elements with an array of possible shapes and configurations. We have used metals in a variety or project types, ranging from new façades to innovative re-cladding of existing structures. Our understanding of each material’s physical properties helps us provide designers with unique solutions that fulfill their design visions.

Façade Materials & Systems


Structures whose exterior cladding is in need of replacement have two options: remove the old cladding and replace with new, or place new cladding over old. The second option eliminates the cost of deconstructing the existing façade and may provide an energy savings by creating a double-skin facade. We leverage our experience with all systems to help determine which option will work best for each project, visually and financially. We work closely with clients to make the transition as seamless as possible.
