Necto Domus, or “Interwoven Homes”, aims to provide comfortable homes for Martian settlers as they adapt to a vernacular lifestyle on the red planet.

Based inside existing craters, Necto Domus starts from a central airport. It would gradually expand outwards with city domes and laboratories. Each dome structure is semi-embedded to take advantage of the stable ground temperature and shield from sandstorms, whilst allowing potential expansions underground.

Following HiRise and Iris Project’s initiative – BeautifulMars Latin – our proposal is named in Latin to acknowledge the Latin origin of Mars’ name and connect the futuristic colony with its Earthian roots.

“Necto” – connection and bind, not only references the physical connection between domes, but more so symbolises the settlement’s connection with its origin, and the strong bond between residents. “Domus”, the Latin root of modern English word “Dome” means home and dwelling. Whilst representing the dome shaped city forms, it echoes with our project’s aim to provide a homely environment.

Phase 1: Earth-Reliant Settlement
Although currently there’s no atmosphere on Mars, scientists and researchers from NASA provided evidence of pre-existing ground water, atmosphere and possible civilisation – ancient ruins – proving potential for human settlement and restoration of its biosphere.
The first fleet would carry materials for a small landing and research base to be assembled by astronauts and researchers. After landing, rovers and drones would be deployed to set up factories, artificial magnetic poles and restoration sites whilst cities expand from this base.

Phase 2: Localisation on Mars
Semi-embedded city domes would be constructed by locally manufactured graphene, glass, metal and rammed earth from excavation. The Martian soil, bounded by iron oxide, is a proven structural material that only requires pressure to assemble. Once the outer structure and levels of city domes are constructed, residents can design, print and assemble individual dwellings, offices etc. surrounded by generous public spaces and lush greenery.

Phase 3: Expansion and Restoration
As atmosphere and biosphere restoration slowly takes place above ground, city domes and laboratories can freely expand, further populating human’s first space colony through intelligent, self-sustaining vertical cities. Life on Mars has a strong emphasis on science and sustainability: each dome is powered by solar energy and geothermal power plants, CO2 emitted from factories are collected for heating and cooking. Agriculture and laboratory facilities are shared between two domes to encourage trades and interactions.

Phase 4: Migration Above Ground
After generations of settlers, the red planet will be covered in plants, natural resources and local species that evolved during the restoration of Martian biosphere. With ground water and oxygen back in place, and luscious views of the progressively greening planet, it’s time to move back on ground! Having witnessed the development and transition of a once uninhabitable planet, Martians had learnt to treasure their environment and coexist with local lives, resources in a sustainable manner. Necto Domus has hence completed its mission, and may be converted into museums, research bases or recycled to construct rammed earth homes on Martian ground.
