Underwater & Floating City

The ability to build without land presents an entirely different sphere for living, where water becomes the landscape and townscape.

Underwater and floating development offers a sea of possibility, and the last few years have seen a proliferation of new underwater and floating architecture projects around the world. Underwater projects can be built on land and placed in the water once complete, or constructed while the water is temporarily held back from the site with dam-like structures. In either case, careful engineering is required to keep the structures strong and water tight. Floating structures have a longer history, but more recently have been growing in scale, with entire office buildings now resting on barge-like floats.

The Underwater and Floating City is at the cutting edge of water living, claiming new spaces for people and providing maximum proximity to the water.

Sea Turtle Heritage Centre

Heritage Centre

The Turtle Heritage Centre is formed of geodesic domes, clustered on the ocean seabed. They are designed to withstand drastic environmental changes, providing large spans of programmable space for visitors to observe conservation and take a closer look at wildlife. The centre’s main goal is to educate visitors about the depleting coral, endangered turtle species and human impact on the marine environment.

Established in 1989 with offices in London, Bristol and Oklahoma City, Allford Hall Monaghan Morris makes buildings that are satisfying and enjoyable to use, beautiful to look at and easy to understand.

Marsh-mallow haven

Bausager & Bouquet

Marsh-mallow haven is a bird habitat and wetland center constructed on floating manmade islands. The islands can adjust to rising water levels and are made from repurposed industrial materials found from the ex industrial zone. Some of the island can be accessed with bridges and a visitor center includes a rooftop garden that acts as a viewing platform for bird watching. The space as a whole is designed to encourage access and connection to nature and allow for the flora and fauna in the area to thrive.

Bausager and Bouquet is a landscape design studio based in London and Copenhagen. We are committed to creating artisanal and environmentally sensitive designs, with a strong focus on spaces that connect people to nature and wildlife. Our methodology is to take both in situ and abstract inspiration from the environments we interact with.

Surrounded by sugary sea, our gingerbread lighthouse helps guide the residents of the Floating City. A gingerbread bridge spans from the lighthouse to shore, allowing the lighthouse keeper easy access to their home when tides allow. At unusually high tides, a boat must be used instead, using the buoy to avoid colliding with the submerged bridge.

Cundall is a global, independent, multi-disciplinary consultancy delivering sustainable engineering and design solutions across the built environment.

Learning in the heart of the wetlands

Metropolitan Workshop

Above the flooded landscape a timber primary school together with a dynamic collection of learning pods are connected by walkways hidden between the reeds and bulrushes. These classrooms, raised on stilts, offer students a unique environment within which they not only learn about nature but they learn from nature.

Jonny Allams, this plot’s designer and maker, is an experienced teaching and learning consultant and highly skilled playground designer/maker. This plot was a perfect opportunity to combine his passion for teaching, creative design skills and recent research completed by Metropolitan Workshop regarding the benefits of biophilic design in schools.

Wandering Waterfalls


Gingerbread people, like humans enjoy taking time to focus on their wellbeing; clearing their chocolate-chip pores in a volcano-heated sauna; cleansing their marshmallow gut by drinking candy cane concoctions, before swimming in a geothermal pool of boiled sweets, and finishing by re-awakening themselves in a chocolate encrusted bubbling mud bath.

Since 1963, PRP has been at the forefront of designing high-quality buildings that enrich the lives of users and their communities. Whether regenerating inner-city estates, masterplanning new neighbourhoods, designing commercial and industrial buildings or homes for older people, our ethos is always the same – intelligent, responsive and sustainable solutions, delivered with professionalism and total integrity.
