PoroCity is a project that seeks to re-organize extremely high density environments into an integrated three-dimensional city while addressing sustainability problems.
The specific site for this proposal is Dharavi, Mumbai, India; one of the largest slums in the world and one of the most contentious sites of the new millennium.
It is poised for being the one of the largest regeneration schemes of recent times and has attracted investments from some the world’s biggest real estate companies and leading global architecture and planning firms. Spread over 216 hectares, the site is triangular in plan, and has a residential population of 376,000 people. In addition to the residential population, the district has an estimated 5000 businesses and 1500 single room industries. A large number of these businesses are hybrid homes, where residents live and work in the same area. There is also a lack of public amenities, including schools, hospitals, and parks.
PoroCity is an urban proposal which addresses the physical and economic concerns of the area while preserving the hybrid homes and the strong communal bonds. It is derived from a progressive subdivision of a right-angled Sierpenski’s Pyramid, giving a range of volumes and voids to incorporate a variety of programs.
The smallest self divisible unit of the Sierpenski’s Pyramid is pixilated into 3m x 9m blocks, divided into collective housing units with north facing terraces. This is done to avoid the harsh tropical sunlight, allowing the terraces to be used during daytime. Larger interstitial volumes may be used as community spaces. As the scale of the blocks increases these are used for small scale infrastructure, such as clinics and supermarkets, while larger units are conceived as educational institutions, factories, and offices.
PoroCity is a car-free environment where means of vertical, horizontal and diagonal access is through elevators, moving walks, escalators, and funiculars. The open ended nature of the system allows for different volumes to be plugged-in and accommodate for growth and change in density.
