Sports Centre — Structure as Connection and Adaptation

Structural Reasoning

The Sports Centre is conceived as a lightweight structure positioned above a series of existing buildings, transforming previously separated roofscapes into a continuous environment for recreation and collective activity. The primary structural challenge is not simply the creation of large-span sports spaces but the need to bridge between independent buildings that possess different structural characteristics, load capacities and movement behaviours.

To accommodate these conditions, the building is organised as a series of structurally independent zones separated by movement joints. This allows each part of the facility to respond independently to thermal expansion, settlement and structural movement within the buildings below. Long-span steel trusses and space frame systems are employed to create unobstructed sports areas while transferring loads directly to known support locations. The resulting structural framework establishes a clear hierarchy between spanning elements, supporting members and existing structures, allowing the building to operate as a coherent whole while acknowledging the realities of its complex setting.

Material Behaviour

Steel is selected as the primary structural material because of its high strength-to-weight ratio and suitability for prefabrication. Minimising structural weight is essential when constructing above existing buildings, reducing additional loading while allowing longer spans and greater spatial flexibility. Structural members are sized according to span and loading requirements, with deeper elements used where large distances must be bridged and lighter members employed where demands are reduced.

The system is designed around prefabricated components assembled through bolted connections. This approach allows elements to be manufactured under controlled workshop conditions and installed rapidly on site with minimal disruption to the occupied buildings below. Connections are detailed to accommodate movement, fabrication tolerances and differential settlement while maintaining structural continuity. The structural system therefore combines precision, adaptability and efficiency within a repeatable framework suited to complex urban construction.

Environmental Response

Environmental performance is integrated directly within the structural organisation. Rooflights are positioned between primary structural members, introducing balanced daylight into the sports spaces while maintaining the continuity of the load-bearing system. The depth of roof trusses and perimeter framing assists in controlling solar exposure and reducing glare within activity areas.

Ventilation openings are coordinated with the structural grid, allowing air movement to occur without conflict between environmental systems and load-bearing elements. Lightweight roof and façade assemblies minimise thermal loading while supporting high levels of natural illumination. Environmental control is therefore achieved through the coordinated arrangement of structure, enclosure and services rather than through the application of separate systems.

Constructive Expression

The architectural character of the Sports Centre emerges directly from its structural response to site conditions. The building is defined by the act of spanning, connecting and inhabiting the space between existing structures. Long-span trusses, bridging elements and lightweight enclosures make visible the forces and constraints that shape the project.

Rather than concealing the complexity of rooftop construction, the architecture expresses the logic of adaptation and assembly. Structure, enclosure and environmental systems operate together as a single coordinated framework whose form derives from the requirements of spanning, movement accommodation and prefabricated construction. Expression therefore arises not from applied form-making but from the clear resolution of structural, environmental and logistical conditions.
