Ocean: The Latest Architecture and News

Throughout history, fish markets have played a singular role in mediating the relationship between city and sea. From the port agoras of antiquity, through medieval markets established along docks and estuaries, to the large covered structures of the 19th century, these spaces have been instrumental in shaping coastal cities. More than simple infrastructures for food supply, fish markets express cultural practices and modes of occupation rooted in proximity to water, consolidating themselves as intense and highly social public spaces. Within them, architecture, landscape, and social dynamics intertwine directly, revealing how the built environment can translate maritime traditions and reinforce the identity of coastal and port communities.

Zaha Hadid Architects' design for a digitally fabricated marine habitat in the North Lantau Marine Park conservation zone in Hong Kong was recently presented at the World Design Congress exhibition in London. The event took place at the Barbican Centre between September 9 and 10, one of the world's most recognized examples of Brutalist architecture. Its theme, "Design for Planet," called on designers and commissioners of design to take on their most critical brief to date: to design a regenerative future in the face of climate change and to examine design's role as a tool for environmental action. In this context, Zaha Hadid Architects presented Nereid, a digitally fabricated habitat developed with advanced 3D printing technologies by D-Shape, aimed at supporting the natural regeneration of marine ecosystems.

At the initiative of the Surf Ghana Collective, architects Glenn DeRoché and Jurgen Strohmayer, the co-founders of DeRoché Strohmayer, set out to transform a small waterfront plot in Busua, a surfing hotspot on Ghana’s western coast. The result is a dynamic community hub, complete with amenities for local surfers, but also providing spaces for the entire community to gather in and off-season. The project has been recognized as the winner of the Gold Prize of Holcim Awards 2023 for the Middle East and Africa commended for the profound local impact and the resourceful approach to construction techniques. In a video interview for ArchDaily, architects Glenn DeRoché and Jurgen Strohmayer discuss the development of this initiative and the innovations that shaped it.

Land reclamation from the sea has become a popular phenomenon in coastal development. It is the most preferred solution to the need for land in coastal areas and has been implemented for various use cases, including flood control and agriculture. Nowadays, it has become a famous urban response to the rapid increase in coastal urbanization, economic activity, and global population. Countries like China and the Netherlands lead the chart on the amount of land area reclaimed. However, most reclamation projects today take place within urban centers in the global south. Cities in West Africa, East Asia, and the Middle East produce these new lands as economic forerunners for their commercial industry and as platforms to house luxury residences.

But the relationship between the design and production of reclaimed lands and the response of water in ocean environments is complex. It requires a symbiotic relationship with water bodies for stability but can provoke natural forces when negligently imposed on the sea. Ocean water behaviors, including tidal accumulation, sea level rise, connection to wetlands, and aquatic biodiversity, can question the success or failure of land reclamation projects in different contexts.
