Structures based on the honeycomb built by bees could house up to 50,000 people at a time by the end of his century, according to an architect.
Nicholas Socrates, who works for Scott Brownrigg Architects in Cardiff, presented his idea of domed construction as an independent urbanist.
Socrates said a UK population of 100M by 2085 would require cities to reinvent themselves to maintain quality of life and prevent urban sprawl.
He said domes would provide working, living and shopping spaces in the sky, with interconnected hexagonal structures maintaining strength while allowing in light.
A column-free, curved formation would allow buildings to span large distances, said the architect, who has an MA distinction in urban design from the University of Barcelona, among other qualifications.
The Dome would generate its own energy through solar harvesting technology embedded within the external fabric of the building.
Socrates told NCE: “The main point of this idea is to prevent greenfield construction. The dome would create another layer of the city.
“One dome could hold anything from 1,000 to 50,000 people. It would be built using prefabricated steel units and could be added to as the need arises.”
While he doesn’t have any plans to pursue domed construction yet, Socrates said he was keen to open minds to the possibilities.
“I want to raise awareness and get people thinking,” he said. “Britain is very conservative. I am trying to change people’s perceptions about what cities could look like.”
