Why Concrete: A Place for Concrete Within the Solid and Void of Auckland in the Climate Crisis

Abstract

A place for concrete within the solid and void of Auckland in the climate crisis. This thesis aims to explore concrete - a formless material that ancient civilisations have utilised to present-day construction, forever regarded as a ‘modern material’. Understanding concrete’s place in the current climate crisis is vital to ensure its correct application, harnessing its beneficial properties and understanding its carbon effects. Throughout this thesis, the following will be explored: the carbon outputs, emotive qualities and history of concrete to understand a more sustainable method of production and application. Interaction with concrete ranges from structural advances to dynamic responses in experiences. The emotive interaction will use the medium of light interacting with concrete to create real-world conditions. Throughout this thesis, the methodology will be in the analog realm. The physical world aspects of solid and void will be developed through sketching and model-making. Treating ‘light as a living thing’ creates the conditions for the concrete’s emotive interaction. Intangible aspects of these interactions will be conducted through the solid and void of casting forms, with added light studies. Themes of light will be intertwined throughout, informed by the findings in Steven Holl Architects and Tadao Ando’s projects. Through exploring Holl’s ideas of ‘under, in, on and above, the underlying history of the site will be revealed. Concretes’ longevity will drive the design, leading to an architectural intervention at Constitution Hill, Auckland. By analysing concrete structures that have stood the test of time, implementing a space to last generations will be explored. Researching the Pantheon as a starting precedent and ending at the work of Holl and Ando Architects, an understanding of the material’s presence and permanence will be grasped. Ensuring the material is utilised to the fullest potential will be a key driver, as the time period a structure stands can change how it is received. As Constitution Hill is located over the exit of the Albert Park tunnel system, the site offers the opportunity to create an interaction with a history that is not known by all. Parallels between the material’s longevity and construction are drawn against the chosen site, bordering the solid and void of Auckland’s reclaimed shoreline. Adjacent to Constitution Hill is the Auckland University campus, a space which tries to create a sense of belonging. The site offers a primary circulation route from Parnell to Queen St; this intersection creates a case to create a structure that utilises pedestrian movement whilst engaging with the public to reveal a lost history of the site. Ultimately, to create a series of interventions with a sense of belonging and intrigue for generations to come.
