The Urban Earth Worm skyscraper uses one of the basest of creatures as its inspiration. Just as earthworms clean the soil and solve pollution problems, promulgating life in thriving ecosystems, this skyscraper will clean air and soil pollution in cities and also feed cities – literally.

Zero by Ekkaphon Puekpaiboon

Zero is a radical skyscraper, designed to ensure mankind’s survival after global devastation. Like an emergency toolbox, it will be the starting point to the reestablish social order through digital communication and information exchange.

Scraper by Jong Hyuk Lim, Seung Jun Park, Sung Wha Na, Jae Chung ko, Ho Young Yeo & Gyoeng Hwan Kim

The massive amount of waste and debris accumulated in the Pacific Ocean is known as the Pacific Garbage Patch. The Scraper is a floating building designed to collect and compact the garbage into cubes with the use of automated robots.

Big Wood by Michael Charters

Big Wood is a prototype on mass timber construction that offers the possibility to build more responsibly while actively sequestering pollutants from our cities. Sited in Chicago; “Big Wood” aims to write a new chapter in high-rise construction.

Sea-Ty by Shinypark, Liu Tang & Lyo Heng Liu

Building an underwater city is the main goal of this project that responds to the sea level rise in the upcoming decades. The US National Research Council estimates that in this century alone, the sea level will rise between 50 and 200 centimeters – leaving some existing cities underwater.

Moses by Milos Vlastic, Vuk Djordjevic, Milos Jovanovic & Darki Markovic

Moses is a decentralized, self-sustaining city unit, populated by approximately 25,000 inhabitants, which offers the transition of men from land to sea, so that the land could be used for food production and the Earth could start its process of self-regeneration from the negative human impact. It functions independently as a city-unit, as well as a cluster of units, which share information, energy, and goods.

Sphera by Santi Musmeci & Sebastiano Maccarrone

Sphera is a new type of living environment, where the citizens of the world will live during the “earth’s regeneration”, by using innovative and sustainable energies. At the same time, the purpose of Sphera is to build an entirely new civilization, where people will try to redesign their culture and generate a sustainable society by creating a global-resource based economy that enables all people to reach their highest potential, a society that protects and preserves its environment.

Aeroponic by Jin Ho Kim

This project proposes the creation of decentralized aeroponic vertical farmlands that will be able to provide enough rice for future generations. The basic structure consists of an array of bamboo parallelograms that create stepping terraces of rice fields.

Quantum Skyscraper by Ivan Maltsev & Artem Melnik

The form of a skyscraper is a growing crystal – a structure characterized by the inconstancy and regularity of its elements. The height of the units ranges from 130 to 180 m. At the full height, in the center of Multipurpose Research Complex (MNC), is a static rod – a quantum safe energy source, which will produce energy in the required quantity. The center of quantum computing, greenhouses, walking tracks and, aeration blocks are placed in immediate proximity.

Water Re-balance Tower by Zhang Zhiyang & Liu Chunyao

By building towers that can collect and purify rainwater and also purify the water from the river, several advantageous things occur: clean, drinkable water is readily available for the city; rising river levels are mitigated before flooding occurs; and clean water can also be pumped back under ground to fix the sinking subsidence problem the city is experiencing.

Crater Scraper by Xiaomia Xiao, Lixiang Miao, Xinmin Li & Minzhao Guo

The Crater Scraper project is an imagined solution for the healing of the Earth’s surface as the planet suffers the impact of major asteroid strikes. Asteroid craters could be filled in with built settlements, holding communities of different sizes (depending on the size of the crater).

Repair Goaf by Liangpeng Chen, Yating Chen, Lida Huang, Gaoyan Wu & Lin Yuan

The project proposes to reuse the goaf and part of the pipelines on the working platforms. The vertical pipelines will work as the chief transportation system. The main volumes are deposited in the site.

Mist Tree by Yeonkyu Park, Kwon Han, Hyeyeon Kwon & Hojeong Lim

Mist-Tree is a skyscraper which can bring new life to Atacama, Chile. It proposes a simple solution to end the drought coming from the high ranges of the mountains. The skyscraper penetrates through the Andes mountain range and captures fog from the sky of the Pacific Ocean.

Promised Land by Chen Yao, Xiao Yunfeng, Li Xiaodi, Xie Rui & Yin Xiaoxiang

The Promised Land is conceived as “humans” final homeland, a self-sustainable city on submerged places, shape as massive cross rising over the water level. The building works as a modular self-assembly system. Prefabricated girders and columns made of reinforced concrete are fixed on the ground as foundation, and then prefabricated floors are placed in order to sustain the different programmatic modules.

Ring of Mars by Mamon Alexander & Tyutyunnik Artem

The Ring of Mars is a closed self-sufficient off-line mega-structure, which contains all functions for comfortable existence and development of all life forms.The ring is designed on the model of linear cities, a circular system for comfortable connection of all parts of the structure as single agglomerate.
