The literature review reveals how the co-existence of permanence and impermanence shapes and alters space, their relationship driving a perpetual state of change instigated by society, time, and architectural qualities. From this dynamic, (Im)Permanence emerges, setting a definition for this relationship, expressed both tangibly and intangibly. Four key manifestations illustrate this notion: beauty, the memory of elements that no longer exist, perpetual change, and a false sense of the defeat of time. Guided by the interpretation of Lefebvre’s theory of space and the Vitruvian principles of architecture, the research develops a theoretical framework for analysing and discussing examples and case studies of (Im)Permanence. The four manifestations are further explored through three local case studies, first via desk research, followed by semi-structured interviews with architects who instigated a degree of change within each space. An objective analysis and a subjective interpretation of (Im)Permanence for each case study reinforce the discussion in the literature review. The dissertation research concludes by establishing (Im)Permanence as a defining spatial reality, with both forces of permanence and impermanence defining the space as a constant state of change is inflicted by its three agents. The research not only lays the foundation for future studies on the topic but also offers a self-reflection on one’s approach towards the realities of spatial (Im)Permanence. Description: M.

The production process can be optimised to enhance the mechanical properties of the material, while reducing the environmental impact of the geopolymer concrete. The aim of this research is to develop a new sustainable construction material by eliminating cement as a binder and utilising instead limestone-based waste materials through alkali activation. Additionally, the research aims to optimise the production process to achieve the target mechanical properties of geopolymer concrete [...] Description: M.Eng.(Melit).

The durability and strength properties of reconstituted limestone containing ‘Franka’ was investigated in 2013. There was a need to investigate the durability and strength properties for reconstituted limestone containing ‘Soll’, to evaluate the potential for turning such excavation waste into a building material. This study investigates the durability and strength aspects of reconstituted limestone, in which compaction loads applied to it vary [...] Description: M.Eng.(Melit.)
