Urban Regulation and Policy
STUDIO BRIEF Indian cities are plagued with, to mention a few, a lack of good quality public realm, insufficient green cover, lack of inclusive pedestrian infrastructure, unaffordable land market, and an over regulatory development framework. Many of these are resultant of an archaic idea of city planning and design but can also be attributed to the effect of multiple city stakeholders and their interactions. These stakeholders (politicians, citizen groups, slum dwellers, architects, engineers, administrators, urban planners/ designers, etc.) and their competing views towards city design and planning materialize in the form of national/State level policies, city-level development plans, city-level building regulations or outcomes of a judicial proceeding. All of which culminate in tangible change. The course aims to understand the competing process of city-making with a specific focus on land markets, public realm, and buil t form. Which will be explored in 2 modules at the City and Area level. The studio is based in Mumbai, owing to a long history of planning and design interventions.

Urban Regulation and Policy
The exercise intended to introduce acts, policies and regulations that occurred in Mumbai over last 10 decades. The layering of multiple situations draws attention to the dynamics of the city that have taken place.

The city of Mumbai has a history that started in the 17th century, when India was under colonial rule. From then, the city has transformed over the centuries, seeing plagues, wars, industrialisation, plagues and most importantly urbanism. This has shaped the city to become what it is today, with cosmopolitan culture, multicultural population, a global city. At the same time, the city sees many stresses on the distribution of resources, population, employment, housing and living condition. This chronomatrix analyses the impacts on impacts of urban interventions through policy and regulation and the development plans by over laying the ever-growing population in Mumbai over the years.

Urban Regulation and Policy
A major part of the population relies on public transport, especially for work trips. For easy accessibility, a higher density can be found around these transport lines. Attributing to the growth from the southern part, the convergence of transport lines, and higher employment rate, there is a higher population density towards the south.

The map shows the wardwise slum population in 2011, Industrial areas, and existing railway connectivity of Mumbai. The analysis shows that a major number of industries are mainly located along the railway. Lower the slum population, a smaller number of large and more concentrated industries ward has. Most of the large industries are located in wards with a higher amount of slum population.

Land Prices, Slum Settlements, MHADA Housing the main transport corridor of the city, which is also a cause of higher land prices. At the same time, the island city area is seen to have a lower concentration of slum settlements resulting from pre-colonial building typologies with servant quarter provisions, as well as the presence of chawls where lower income families can be accommodated.

YEARS
The countdown has begun, Mumbai has 50 years left to live (or to save itself?). There is one submarine. Who gets to be on it? Actors? Migrants? Slum dwellers? Ambani? Who are the true Mumbaikars? Who does Mumbai belong to? Currently, seeing the way the distribution of resources is done, it is very easy to think that Mumbai belongs to those who have the money. Everything seems to favor them, their seaside apartments, private sealinks and even prime land across the city.

I come from two
MUMBAIS
But those it does not favour have carved out a space for themselves in Mumbai regardless of what the city has given them, in both intangible aspects such as culture as well as in the physical city. Whereas the city sees no flaw in embracing their cultural and economic contributions, it still refuses to make physical formal space for them (housing, sanitation, infrastructure). So it is evident that there are two Mumbais. The Mumbai of the rich, the privileged and the Mumbai of the poor, the migrants.

Urban Regulation and Policy

to the
City
1. The Public/Private Mix Up Just as with the larger city, in Lower Parel, the migrant community’s life is far more intertwined with the immediate public life of the area. Their housing, be it chawls or MHADA and SRA schemes, are located right on the main roads as well are their temples, shops and the governemnt schools.
2.
Mill Land Interactions
Historically, mill lands were a place of interaction between the migrant community and the landlords or upper middle class people. Although that relationship was often exploitative, the mill lands stand for the merging of the two classes. Today, those large green spaces they lay either abandoned or redeveloped into high rise paradises that serve only the rich.
Where is the privacy for me and my family? Our private lives at home are always in the eye of the public.
3. Open Green Spaces?
Private open space
In the urban jungle of the city and the site, public open spaces are far and few. They are hidden away between the built forms and hardly used by the people. For the migrant, a green space he glimpses through a fence on his way back from a long day of work. For the rich man, a green space he glimpses from his tower. They both would like to visit, but hardly ever do.
Public open space

Key Observations Streets
There is abundant vehicular access around the site and fewer local roads that by default downplay the on-foot users.

Urban Regulation and Policy
Commercial activity
Private housing is able to distance itself considerably from the rest of the public realm compared to public housing, creating a segregation in the spaces where people exist on a day-to-day basis.
Problem Statement Today, Mumbai stands divided economically and socially. Why does it have to be like this? Can the two Mumbais become equals so that even the worker, even the actor and even the businessman have the same opportunity to grab a seat on that submarine because each of them have contributed equally to the city?
Scope As Urban Designers 1. Provide opportunities in the physical realm to change the norms of the social.
2. Redistribute the land resource through the public realm and establish ownership and belongingness for a wider range of users.
3. Design spaces that facilitate a coexistence between the people to make one Mumbai
Vision Statement The vision of this project is to challenge the norms that are present today vis a vis the built environment and its adjoining open spaces and ownership biases. By re-imagining the functions and character of the public spaces, the aim is to create a prototype - a pilot - which can bring physical and social connections to the forefront of public life.

SITE CONTEXT Kamala Mills: Lower Parel, Mumbai The site is located in the southern part of Bombay. It was home to many mill workers that worked in the industries in the Lower Parel area, Kamala Mills being one of them. Over the years, the mill lands were sold to private developers like the Lodha group. As a result, the plots that were originally mill lands, now don’t retain, neither its built character nor the social character.

CHANGE THE GAME The Urban Rule Book
In this project regulations and policies act as game changers, trigger points or initiators to create built and open environments. Today, the regulations are framed such that build form is the central player while public space shapes around it. This project explores the possibility of having dynamic spaces and functions through regulations, thus making it an “urban rule book”.
Free Design: Initially each urban condition is to be thought of and designed. FSI, margins, building heights and a such kit of parts of self designed regulations are to be applied to a specific urban condition. Constrain Design: The same urban conditions are to run through the existing regulations and policies designed by Indian government.

Responding to the existing conditions on site, this block is proposed as a commercial sector. The connectivity from arterial and sub arterial road makes it an active block. Commercial areas are prime spots for public interactions. The idea is to monitor these interactions through regulations. Continuous public spaces that are in collaboration with private properties can be designed. (Privately owned public spaces are one way of such approaches) Commercial 59

Analysis The changing FSI in free design did not affect the density achieved but gave opportunity to accommodate higher densities. In residential condition (UC1) the FSI even if is lower than constrain, it achieved higher density because of the ground coverage. In mixed use plots (UC3) as well the densities achieved show that higher ground coverage values have higher densities. Thus, along with FSI it is the ground coverage as well that defines the volumes. 89

Public spaces are essentially waste spaces or left over spaces because their function is not defined in the regulation. It is seen that in UC1 40% is public land but use is limited to a ground or a park.
Functional public spaces having new programs must be imagined. According to context the regulation must define the function of the public open space. POPs must be included in commercial plots.

Non Negotiable 1. The transition between public and private is defined by the multiple layers between built and open on the edge. Designing streets for not only private vehicles but for multiple users is must. Proritising footpaths, cycle tracks and such slow way lanes is one way of including them.

needs to be on the submarine!
Access to commercial building and spill over spaces must accommodate the footfall. Compound walls must be made porous with heights responding to the function of the plot.
2. Functional public spaces having new programs must be imagined. According to context the regulation must define the function of the public open space. While allocating POPs the space must be visually accessible and the ratio of soft and hard landscape must be defined.
“Hum jahan khade ho jaate hain, line wahi se shuru hoti hain ”
Open space must be bifurcated into clear front open spaces and marginal spaces but should be functional.
3. Defining minimum ground coverage is must in the regulation. Currently clear open space, built area and margins are defined that shape the ground coverage, but this leads to high rise structures that leave huge open spaces that many a times are used for parking.
TWO MUMBAIS 93
Urban Regulation and Policy
Approach Finally, who sailed in the submarine? Cities work in multiple layers and transformation on this scale takes years. Regulations and policies are game changers in this process. They define the inter mingling of public and private realm. In Indian context policy and regulations are seen as lengthy long documents that are to be referred only by a certain group of people. Why can’t the policies be accessible to all user groups? They must be written in more interactive format that can be understood by many. The physical elements can be represented by drawing manuals or handbook that can be understood easily. Another aspect is what are policies defining and prioritising. Currently, the regulations are intensely talking about built and it’s functioning inside the plot. The FSI, build area, setbacks and margins are the starting point of the discussion right now. The open space inside the plot and that overlooks the public realm is not defined, the functions in them are not decided. Essentially, while drafting the policies the built is thought first and then the open spaces, thus making them backyards, parking lots, dump yards, basically, left-over spaces. The physical as well as social factors define the working of the city. While Mumbai is home to actors and the richest, it is also where the poorest reside. But where are they living? The policies not only define the physical leftover spaces but also the social “left-over” groups. The fringes of the cities, site next to polluted rivers become the relocation zones. The need to make livable spaces for all must be addressed through regulations. Designing public spaces that are not only gated parks but transitional open spaces such as interactive streets, innovative functions that change with time, inclusive non-motorised paths, brings in dynamics in the space. The need to think about public realm through policies is essential. After all it is on these grounds the two Mumbais in every city will meet!
