The project is a response to the research thesis that aims to investigate the potential of complex geometries in architecture through a rationalisation method of structural objectives such as stress line typology optimization into an architectural spatial objective. through exploring design and structural objectives through investigation of principal stress lines informing an optimal material continuity for structural and environmental performative design. This subsequently leads to a concrete long-spanning system that is tested on a spatial architecture proposition through investigating its fabrication method such as concrete casting to a modular concrete tectonic approach that extends itself to the principles of low carbon construction, economical and sustainable benefits. 

This architectural spatial proposition is set to test the research and methods developed in Studio 1 and 2. This relates to a programme and brief; UK's busiest and only hub airport Heathrow set out having an expansion plan to address the rise of passengers of the recent decade while setting a clear baseline and ambitious reduction targets to reduce embodied carbon from expanding the airport. This is achieved through improving sustainable transport modes and public transport access when Heathrow expands, thus the architectural design application is a redevelopment of Heathrow Central Bus station.
