This thesis proposes an alternative development for the Odaiba reclamation site. This alternative consists of terrain manipulation and modified infrastructure, as well as procedural guidelines. By forgrounding the artificiality of the landfill site, and providing spaces for occupation outside those typical for consumption, these alterations will allow the citizens of Tokyo to experience the site as a unique territory outside of the traditional systems of Tokyo. It is a new system, that will continue to exist---and be transformed---as the site is inexorably assimilated into Tokyo itself.
