This paper presents an examination of ground motion observations from 20 near-source strong motion stations during the most significant 10 events in the 2010-2011 Canterbury earthquake to examine region-specific systematic effects based on relaxing the conventional ergodic assumption. On the basis of similar site-to-site residuals, surfical geology, and geographical proximity, 15 of the 20 stations are grouped into four sub-regions: the Central Business District; and Western, Eastern, and Northern suburbs. Mean site-to-site residuals for these sub-regions then allows for the possibility of non-ergodic ground motion prediction over these sub-regions of Canterbury, rather than only at strong motion station locations. The ratio of the total non-ergodic vs. ergodic standard deviation is found to be, on average, consistent with previous studies, however it is emphasized that on a site-by-site basis the non-ergodic standard deviation can easily vary by ±20%.

The contents of this dissertation explores the renovation of Noah’s hotel which was left abandoned after the 2011 Christchurch earthquake. With the current state of New Zealand as of now, rent prices plummeting, and the ongoing mass emigration proves the country’s increased cost of living. A trend of ‘hidden homelessness’ in the forms of couch surfing and overcrowding tenancies evinces a mass economic displacement. This thesis is driven by means of speculation and of hope that by utilising Christchurch’s dilapidated sites can be transformed into safe havens for those evicted. Guided by the six principles of heterotopia introduced by Michel Foucault, the proposed co-living hotel determines to attest societal perception of hotels, and introduce a reality that alleviates a community from political and economical instability. In terms of Christchurch’s landscape, the hotel itself lies within Maltese Cross, layout planned in 1850 which defines the CBD’S unique urbanscape. Historic landmarks and erected projects use the cross as a guide in tandem with legislative policies strictly imposing the importance of view protection for heritage buildings - a notion made compulsory especially after the earthquake. By taking inspiration from Gordon Matta-Clark’s methodology of Conical Intersects, voids through the building act as viewshafts, each introducing key sites important to Christchurch. These voids simultaneously house integral communal areas and narrates a timeline of Ōtautahi’s crucial events
