About MODE GAKUEN Cocoon Tower
The Cocoon tower presents an incredible case-study for creating a university in the sky. Not only is the organization of the spaces both radical and logical, the resulting aesthetic is quite startling. The separation of classrooms in plan to allow the creation of interstitial lounges is a very clever solution, bringing a vital mix of larger-scale spaces into the building. However the way that this changing plan is resolved into 3-dimensional form is perhaps the greatest achievement architecturally. One has to study the plan and mass for some time to understand how this has been achieved. See Project Case Study
