Before we Retreat

Climate change and rising seas threaten Aotearoa, New Zealand’s coastal settlements, which are rooted in the Tangata Whenua tradition.

As risks increase and advancing tides endanger these coastal lifestyles, safeguarding coastlines has become urgent. With properties at risk and the demand for continued urban development, Eastbourne needs adaptive strategies to thrive amid these changing conditions. How can its architecture adapt?

This thesis proposes proactive design interventions to adapt before retreat. Retreating would protect from encroaching seas but alter the essential social fabric woven into the coastal landscape. This research, therefore, advocates adapting as the primary approach to resolving this potential crisis.

Drawing on traditional and design-led research, it delves into the historical, cultural, ecological, and social contexts shaping Eastbourne.

Engaging in conversations and employing photography, mapping, and drawing analysis, the research process has led to an empathetic design that reveals architecture’s potential to reimagine coastal communities.

It further examines the complex interplay between climate, people, and buildings, redefining their relationship. The goal is to uncover adaptive strategies to empower residents while benefiting coastal communities.

Site visits and analysis informed proposed interventions, including an adaptive ferry terminal, Climatorium, urban wetland, and phased masterplan. These strategies aim to elevate protection, enable staged managed retreat if needed, and integrate buffer zones.

This thesis promotes responsive planning, addressing challenges and increasing resilience. Serving as a coastal adaptation model that extends beyond the conventional, it aims to contribute to a sustainable and vibrant future for Eastbourne and coastal communities.
