Can 21st century Britain really still build something this ambitious?

Yes. Stratford City proves we can do this. That development showed we can create pedestrianized, human-scale environments where children can run free because the world was designed with them in mind—safe, walkable neighborhoods built to exceptional standards. If we could do that for the Olympics, we can do this for the nation. For the sake of the next generation, we have no choice but to continue believing we can still do remarkable things.
