The city of Mumbai also famously called the “maximum city” has undergone a series of socio spatial transformations for the past 200 years, which were dictated by the interest and objectives of powerful institutions coupled with the constant influx of people in the city in search of employment. The famous skyline of Mumbai that we see today is a product of several acts and policies implemented from the 1800s where the city was dotted over by fishing villages to 1900s where post independence we see the city emerge as a strong financial capital and the implementation of land use policies to decongest the island City. The matrix is an attempt to understand the nitigrities of the acts and policies and its impact that has transformed the city of Mumbai from a fishing village to today a global city with world class infrastructure.

Problematising the city

Intoducing the Paradox

Vision and Analysis

Strategies and Concept Plan

In this part of the manifesto we attempt to question certain existing infrastructural systems and patterns in the city of Mumbai.

Here, we discuss the dissociative image of the city with various set of infrastructural models that portray the paradoxical nature of the same.

In this part of the manifesto we propose the idea of ‘city as a single infrastructure’ suppoerted by detailed analysis of both the city and site.

Here we present strategies and a conceptual plan of the site in accordance to our analysis and vision for the site.


01

Problematising the city


Indian cities that are often stylised as kinetic, consuming, maximum and vibrant that fuse physical and visual contradictions on a landscape of incredible diversity. They are acknowledged for its socio - cultural values and the environment that they create to offer numerous opportunities for various activities to be performed in the public realm. Indian cities have been inherently compared to the western cities. Mumbai, also known as Bombay is the financial and commercial capital of India. Over the course of the past 200 years, Mumbai’s socio spatial planning has been subject to various acts and policies that have shaped the city’s skyline today. The city has been often associated with names like “world class city” providing great infrastructure and services. With rapid urbanisation and globalisation, the city’s infrastructure has been consistently equated against its economic outputs.

Idea of Equality?

Needs vs Aspirations

There’s a dissociative image that constantly oscillates between the needs of the people against the aspirations of the decision makers. Wherein, the actual needs of what the people expect of the city are neglected and equated against the paradigm of global infrastructure. These infrastructure projects are exclusive in nature and are mainly transit orientated and economically driven. The constant rift between needs and aspirations has created a paradox within the city and the idea of equity has been disregarded, religiously. 12

02

Introducing the Paradox


The paradoxical nature of the city can be viewed through various housing, business and transport models. Infrastructure operates at two scales, one being at the city level and other being at the neighbourhood level. At city level necessarily we look at infrastructure projects like Local Trains, which cater to the needs of the city whereas at the neighbourhood level we concentrate more upon connectivity that feeds on the larger systems and also is an infrastructural system within itself. With this as our backdrop, there are several neighbourhoods that contribute to the paradoxical nature of the city, one of them being, Kamla mills. Kamla mills is located in Lower parel area of Mumbai. The site land was originally mill land composed of 130 mills. It was torn down over the years, as a result of globalisation. The redevelopment began in 2001 with the DCR 58 being amended.

Kamla mills

introducing the paradox

piecing up the paradox


Residential Paradox City Mumbai houses one of the most exorbitant residential communities alongside the largest slum in Asia. 42% of the total population of the city lives in slums.

Site The mills were a major employment generator also creating a need for developing affordable housing on site. The site could have been developed catering to these housing and economic needs of the people instead it was majorly purchased by Lodha groups converting it into an upscale residential community catering to an exclusive population today.


Social - Commercial Paradox City There are upscale commercial malls against most vibrant informal markets thriving in the heart of the city.

Site The upmarket development has caused social segregation as only a set number of people are allowed to access major parts of the site. There is a significant absence of green open spaces and inclusive public recreational spaces which has created a social paradox on site.


Social - Recreational Paradox City The city’s iconic marine drive is well kept and maintained as it is in the eye of one of the most exorbitant neighbourhoods, which is also a reflection of the visionaire of the city. Against Juhu chowpatty that is being neglected in spite of being a prominent public attraction.

Site The residential parts of the site house few recreational open spaces. Yet, they are very exclusive in nature and are not accessible to all. The site today is a prominent entertainment node at city level with high end restaurants and pubs that are open to only a certain class of people.


Transportational Paradox City The Mumbai suburban rail which is known for its highest ridership can be viewed against Bandra-Worli sea link which is an exclusive transit infrastructure that caters to only 1% of the total population.

Site The Elphinstone Flyover cutting through the neighbourhood acts as a strong connection for high speed mobility but acts as a strong division in its surroundings. The elite nature and characteristics of the site alongside the presence of gated communities have disconnected the site from its neighbourhood and made it exclusive.


Ecological Paradox City In view of the city’s ‘development’ over the period of time, ecological aspects have been conveniently ignored. For example, the Sanjay Gandhi National park is a reserved park alongside the Eastern coastal road that will only lead to more ecological disasters in the city.

Site Ecological condition of the site has been disregarded multiple times, as majority of the land is owned by private developers who believe in utilising every piece of land for maximising their profits. Major part of the site consists of Private exclusive open spaces despite of mumbai being in constant crunch of Inclusive public / green open spaces.


A constant notion of overlooking the existing logics or system and developing something that falls under the intransigent definition of physical development has been followed. This “planned infrastructure� seems to have lost sight of its effect on its genuine users, as well as its capacity to act as a multiplier of social equity. Thus, it becomes imperative for us to review the development and redefine these rigid connotations of infrastructure in our cities.

Vision and Analysis


City as a Single Infrastructure

36

vision and analysis


We propose to view infrastructure as an integrated system wherein it caters to the basic needs of all irrespective of their differences. Residential Infrastructure: Housing that caters to the needs of the people i.e. well-lit, ventilated, adequate water and sanitation facilities, with revised standards for per person built/open spaces. Cities function as a cohesive system composed of different sets of infrastructure such as social, cultural, economical, political, residential, ecological and transport. Each of these have interpersonal and intrapersonal relationships. Thus, lack or excess of any one set of infrastructure largely affects or disrupts the entire network. Providing basic necessities such as housing, water, sanitation, education open-green spaces and better connectivity are few set parameters against which we weigh the qualitative aspects of livelihood. Current paradoxical situation is a result of many such systems which fail to strike a balance between what is required and what is being offered.

Commercial Infrastructure: Socially inclusive multi-functional spaces that allow multiple stakeholders to engage. Transportational Infrastructure: Equal and proportionate distribution of modes of Transport. Streets that cater equally to pedestrians as well as vehicular traffic and encourage social encounters and interactions by accommodating multiple users. Ecological Infrastructure: Development that supports Blue - Green infrastructure. Legal Infrastructure: Policy making should be developed understanding the ground realities and the needs of the people, backed with factual data. These policies should be accommodating and inclusive as a strategic imperative. There should be a strategic balance between top down and bottom approaches that harness the potential of the space. Social Infrastructure: Developing inclusive open spaces that breaks the barrier of exclusivity and builds a sense of community.

VISION The site severely lacks connectivity and is inaccessible as most of the area falls under private ownership. The upmarket development has caused social segregation as only a set number of people are allowed to access major parts of the site. There is a significant absence of green open spaces and inclusive public recreational spaces. Thus, our vision for the site is to break the conception of exclusivity. The idea is to make it more ‘public friendly’ such that it integrates the site’s subservient infrastructural needs with the existing ones to create a holistic environment as a response to the current paradoxical nature of the city as a whole.

- city level public open spaces like parks and plazas without prominent physical boundary walls can create more inclusive and welcoming edge with the street - no compund walls encourage ‘built to line’ typology which maximises possibilities of chance encounters, spaces between buildings can be used for different time based activities and can be open to city - setbacks and margins are used as semi public / public spaces / extended spaces of the built which provides smooth transition spaces from public to private [PPP model] - podium typology gives opportunity to create interactive edges, spaces in front of the commercial/ mix use buildings can be used as semi public spillover spaces to create more interactive edge with the street - human scale and sky view factor is maximised, despite of high rise buildings

- city level public open spaces with compound walls create clear demarcations even within the public domain which discourages the direct visual or physical access and ends up creating dead edges with the street - compounded commercial buildings create more exclusive private spaces with insufficient space on the street for public domain - FSI helps in controlling the building height - footpaths and public open spaces abutting high compound walls create dead edges and negligible interaction on street - poor and insufficient street infrastructure discourages people to walk - human scale is maintained, however it creates poor living conditions

margins of the plot play important role

margins of the plot play important role

in between spaces of the buildings create liveable/ unhealthy spaces

restrictions on built footprint can also be an important guiding factor for built volume and height

form based codes with height restrictions provide multiple opportunities for multiple built form explorations

form based codes with height restrictions can provide opportunities for multiple built form explorations

mix use can work as an efficient building typology, it can eventually create inclusive neighbourhoods in between spaces of the built forms and plots of the commercial plot can be at least open to pedestrians and boundaries can be visually porous for visual access

vertical distribution of land use in mix use building typology can be used to create compact yet efficient neighbourhoods re-imagining the plot boundaries can invite more people to the streets by prividing interactive/ extended spaces on ground

in between spaces of the built forms and plots of the commercial plot can be at least open to pedestrians and boundaries can be visually porous for visual access smaller plots and respective abutting streets restrict the overall height of the built form

human scale should be given utmost importance despite of all other factors considered to achieve maximum built volume

maximising sky view factor with rising densification and high rise buildings

re-imagining the plot boundaries can invite more people to the streets by prividing interactive/ extended spaces on ground

city level public open spaces shall be integrated with the abutting streets and land uses such that it creates welcoming edges

the quest of achieving maximum built volume rises the need of resources in the overall plan

equal importance to front, rear and side margins

certain setbacks at upper level should be provided as open to sky semi private open spaces in respective built form for shared use

comparision

front, rear and side margins should be imagined as interactive transition spaces and shall be given equal importance

sufficient provision of n-between spaces of the buildings shall be taken into consideration

open to built ratio and provision of minimum per person open and built spaes should also consider access to healthy environment with quality spaces as one of the guiding factors

provisional regulations should also consider introduction of additional open spaces at different levels such that it enhances the quality of the living environment

podium typologies should be created to have more interactive and dynamic street edges with mix use


Approach Regulations play a major role in city building process. It is a powerful tool to shape and sharpen the crux of the city. Importantly, there are number of aspects at play when it comes to building a ‘healthy neighbourhood’ or a ‘people centric neighbourhood’ or a ‘liveable neighbourhood’. All these aspects have their respective bars and boundaries set to be achieved. However, the actual life thrives within these boundaries. Seems like it is taken quite literally that these boundaries have started segregating and piecing up the cities which has eventually created secluded, classified and exclusive neighbourhoods. Current paradoxical situation is a result of many such systems which fail to strike a balance between what is required and what is being offered. A constant notion of overlooking the existing logics or system and developing something that falls under the intransigent definition of physical development has been followed. Currently, it is more like a problem solving approach wherein each aspect of the city development is observed and addressed through separate set of regulations in isolation. Densification and growth of the city shall be addressed more holistically which doesn’t only provide basic infrastructure needs and services but also enhances the quality of the living environment. Certain aspects such as the built form, street edges, open spaces, inbetween spaces shall be looked at altogether and the regulations unlike in current situation, shall talk more about creating more inviting and interactive spaces than just creating individualistic buildings. It should focus more on the in between spaces, interactive street edges and smooth transition spaces between the public and private realm. The notion of exclusivity and divide shall be addressed through a cohesive approach which also encourages to build more dynamic and interactive spaces and edges, both on ground and vertically. So as to start with, the best approach to piece up the paradox is by putting the pieces together!
