Abstract
This thesis aims to develop an alternate solution for land reclamation in urban expansion. Hence, by adopting flotation technology, which is successfully implemented on building on water in recent years, living on water for larger scale becomes an impending trend to our future generations. To establish a new urban context that can be seen as a benign solution to ecological system in urban expansion, the new city is established in distributed and porous form to allow more sunlight can be accessed into underwater layer. This can facilitate the growth of marine creatures such as coral reef and microorganisms under the coverage of the new city. To merge the gap between residents and users in new urban context, a walkable city, which is a highly interconnected city in terms of urban network and building arrangement. This can create a more dynamic urban living environment in new urban context.
