With this project, we have tried to challenge the established method of urban development in harbour areas. Conventional construction methods have a massive carbon-footprint, as well as insufficient conditions and surfaces for marine life. By altering and adjusting the building elements we are proposing a project with a negative carbon footprint that regenerates nature in the Oslo fjord. The typical building platform is now lowered into the sea, as a structural grid with openings allowing sunlight and water to pass through, imitating a new seabed as breeding ground for marine species. From the seabed and upward, everything is built in wood, and elements exposed to seawater are therefore protected with a layer of treated hardwood – preventing absorption of water - and therefore any damage from decomposition or shipworms. The constructive method and facilitation for biodiversity also gives unique qualities for life over water: Sunlight, views, and access to the sea surface. A neighborhood for all species.
