dc.description.abstract Te Waihora/Lake Ellesmere is New Zealand’s most nutrient-polluted lake. It is also a crucial wetland habitat of its type in New Zealand, providing essential residences for a broad range of wildlife species. To Ngāi Tahu (the local iwi), it represents a significant mahinga kai and a necessary source of mana. To all New Zealanders, it once was an important location for both commercial and recreational activities. A yearning to learn more about Te Waihora/Lake Ellesmere and contribute to its betterment is the motivation for this thesis. A cause of The Lake’s pollution is the restricted drainage and lack of a natural outlet, despite the fact The Lake is in close proximity to the sea. More recently, it has been ravaged by the nearby dairy farming industry, with harmful phosphates and nitrates leaking into the river beds that feed the lake. Te Waihora/Lake Ellesmere has been temporarily opened to the ocean for generations to counteract these problems. Proposals to fix Te Waihora/Lake Ellesmere have failed because they do not meet local stakeholders’ needs. The proposed construction of a permanent outlet designed to clean the Lake was vetoed because of the potential loss of mana for the local rūnanga, Te Taumutu. They have traditionally relied on the seasonal lake opening as a source for kaimoana. Nutrient restrictions for farmers introduced by local councils will partially reduce nutrients in the long term but come at a substantial economic cost to local farmers and the surrounding community. Thus an alternative scheme needs to be proposed. This thesis proposes a functional architectural solution that rejuvenates the lake while balancing the needs of these stakeholders. The solution consists of three interventions: a modular lake farming system designed to remove nutrients from The Lake and provide a viable economic alternative for farmers. The second, a working village intended to complement the lake farming operation. The third, a hybrid landscape of mechanical and environmental infrastructure (constructed from non-invasive materials) designed to control the height and salinity of The Lake while also maintaining mana for the iwi by allowing them to harvest kaimoana in the same way they have for generations. All three interventions are to be interwoven to encourage agri-tourism in the local region. At its core, this thesis documents the processes, research, and designs undertaken to find an architectural solution to rejuvenate The Lake. It also addresses water pollution issues through cost-effective, innovative, and responsible business practices and supporting architectural infrastructure. This thesis proposes a new floating farming industry in New Zealand, reimagines the systems and processes, and develops the necessary infrastructure through architectural processes.
