An idea whose time has come.

The Market Town is a natural bubble, within which each of the 20 side-by-side villages are micro-bubbles

Pandemic lockdown was not a design consideration when the Market Town plan was developed.

But it addresses the need with no change. Its economy is self-supporting in good times and bad. Only one road in, with goods transfer in the freight depot. Lock down is as simple as closing the gate. If infection occurs, seal each village. The design is inherently future-proofed, not only for pandemic, but many other catastrophes that may unfold.
