The Georgia Savannah and the New York Manhattan differ greatly in the way they form and use city parks as a shared space. The Savannah takes the form of an absorbent pocket park that provides daily breaks to residents in close proximity by placing several small parks at certain distances. Yet Manhattan puts a large park in the center of the city. As a bigger sharing social function it supports various activities and events shared by all citizens.

Mega Floor is a proposal for a new prototype of a ‘sharing’ office. In general, if an office/rental space is placed on four sides facing outside with a centered core, the shared and public space is located in a small area in the center of being environmentally marginalized. The area size and environmental performance should be improved considering cooperation, sharing and synergy with various companies in the framework of the AI-driven 4th industry.
