The design concept of PRIVATE/PUBLICTRICHOTOMY isparticularly suitable for modern urban environments withscarce resources and dense populations, breaking through thetraditional practice of strictly distinguishing private andpublic spaces.

The building is divided into three equal partsvertically, with the spaces on both sides sandwiching theinner column in the middle, which includes public functionalspaces, and then the horizontal axonometric constraints arebroken to make it translate vertically.This design can create fexible multi-functional spacesand implement shared spaces under the sharing economy.Theextended roof becomes a bridge connecting buildings and units,which not only improves the effciency of space use, butalso provides users with a more diverse and fexible way ofliving and working.Especially in the context of transcendingthe traditional private/public trichotomy, it means breakingtraditional boundaries and maximizing the functionality anddiversity of space through innovative design.
