Bike paths for high-rises

Summary

"What if it was easier to build high-density housing that encouraged cycling by making it seamless to get from door to street? That’s the aim of the West Village Basis Yard in Chengdu, which was finished last year. Aerial streets connect the levels, and slopes allow cyclists to rise and descend as though they were on a hill."
