Seeking to tackle societal issues such as overpopulation and the continuing threat of higher sea levels, these aquatic communities could be potential solutions. In honour of the contest, below are seven amazing designs of eco-friendly floating cities that some may one day call home.
Prefab self-sustaining floating city – Designed By AT Design Office
With the highest population in the world, it’s no surprise that China is deeply concerned with overcrowding throughout its cities. CCCC, a Chinese construction firm, commissioned AT Design Office to design an attractive floating city using prefabricated hexagonal modules to support a sprawling buoyant landmass.
With self-sufficiency also being a target, the island is energy efficient, zero-carbon, and would even include fish hatcheries and vertical farms for the production of its own food.
Noah’s Ark – Designed By Jelena Nikolic & Aleksandar Joksimovic
Noah’s Ark, designed by Jelena Nikolic and Aleksandar Joksimovic of Serbia, came up with a self-sustaining floating city inspired by a post-apocalyptic world.
Using renewable solar and tidal energy sources, the structure has ring-shaped landmasses with agricultural fields designed to capture water at their center.
X SEA TY – Designed By X-TU
X-TU created a lush floating city called X SEA TY, using carbon-absorbing technologes to clean the air.
Taking inspiration from a hive based structure, the buildings would be built using porous concrete with living walls overlaid, covered with a photosynthetic algae.
The algae systems would produce biofuel energy that would be used to power the self-sufficient floating city.
Harvest City – Designed by Tangram 3DS and E. Kevin Schopfer
When Haiti was devasted by the 2010 earthquake, Tangram 3DS and architect E. Kevin Schopfer worked to design an innovative floating city with the intention to bolster economic recovery.
Named Harvest City, a collection of artificial islands, the vision was to create a new Haiti using tethered floating modules. The city’s center would be designed with urban functions such as office space, education, and light industrial businesses, with the outer areas dedicated to agricultural lands.
The Lilypad – Designed By Vincent Callebaut
Lilypad, designed by Vincent Callebaut’s, is quite possibly the most beautiful floating city proposal ever. Inspired by the shape of a water lily, each individual community could house approximately 50,000 people within its mixed-terrain landscape.
Self-sufficient and with zero-emissions, Lilypad uses renewable energy and is envisioned to be a future home for climate change refugees.
Green Float – Designed By Shimizu Corporation
Prior to its brilliant designs for a seabed-powered underwater city, Japan’s Shimizu Corporation revealed Green Float – plans for a floating ecotopia that is self-sustainable.
Designed to house up to 1 million people, a series of modular islands connect the floating city. At the center of each island is a 1,000-meter-tall mixed-use eco-skyscraper, housing a vertical farm as well as office, commercial, and residential spaces.
Silt Lake City – Designed By Anne-Hina Mallette, Margaux Leycuras, and Marion Ottmann
Proposed by a student architecture team, Silt Lake City is a floating “hydropolis”, it’s primary focus targeting Nile Valley flood control.
The city is built on one of the largest man-made lakes in the world, Lake Nasser, and this competition-winning project proposes the division of the lake into floating modular cities that could “ride” the tides during flood season. Each city would include energy generators, businesses, residences, and argriculture.
