Studio Brief This studio will focus on the design aspects of urban transformations within the existing urban areas. The underlying context is that Indian cities are growing rapidly in terms of population and therefore expanding physically. Increasing urban population and the growing urban incomes will fuel demand for more and more built-floor space in cities accompanied by a demand for infrastructure.Many urban areas within these cities are dealing with unstainable levels of stress on infrastructure, resources and public services and are becoming increasingly unliveable.

UD4002 Urban Transformation Studio Tutor: Prof. Purvi Chhadva

As an attempt to address these concerns, the Ministry of Housing and Urban Affairs (MoUHA) has initiated various schemes such as AMRUT (Atal Mission for Rejuvenation and Urban Transformation), SMART CITIES MISSION and HRIDAY (Heritage City Development and Augmentation). These schemes enable planning for developing infrastructure in the brownfield areas through mechanisms such as Local Area Plans (LAP) and Town Planning schemes (TPS). These typically include those parts of the city that area already developed but are not able to sustain the pressure of existing infrastructure Students will work on the projects that are emerging out of these initiatives defined by their studio tutors.

Studio Brief UD4002 Urban Transformation Studio Tutor: Prof. Purvi Chhadva

Through their design projects, students will explore the methods of integration of the physical design with the regulatory frameworks (TPS, LAP) in creating liveable, functional, memorable, safe and sustainable urban areas. The projects will have a strong design focus on the physical setting, however issues of private ownership and social equity, land economics, planning models, project finance, and implementation strategies will also be addressed. The learning outcome of the studio will be to: 1. Prepare strategic framework plan of delineated areas with identified design projects 2. Detail design of the identified urban design projects 3. Prepare building regulations for the intended urban form outcome for the project areas 4. Prepare a planning model for executing the proposed framework plan and carrying out various public place design project 5. Prepare Detailed Project Report to communicate effectively all the aspects of the project

INTRODUCTION Transit Oriented Zone Local Area PLan Site Context Access & connectivity Built form Public Realm Stakeholders Assessment LAP Proposal: AUDA

08


TRANSIT ORIENTED ZONE Ahmedabad is transforming rapidly with huge influx of population leading to the expansion of city boundaries. Today the city is experiencing paralyzing traffic congestion, long travel times, lack of last mile connectivity, high cost of housing and real estate, increased demand for amenities, gardens, open spaces and much more.

NEED FOR TRANSIT ORIENTED DEVELOPMENT If the city is to grow as a livable and sustainable place, it must plan and organise its land resources. For which, there is a need for Transit Oriented development (TOD), a compact- mixed use development with thriving residential, commerical, entertainment activities within comfortable walking distance from transit stations, to maximise use of public transport.

Ahmedabad has identified Transit Oriented Zones (TOZ), along the public transit routes- BRTS and Metro, 200m wide zones on either sides of the corridor. TOZ zones will be eligible for an increase in FSI. From FSI of 1.8, the new permissible net FSI of 4.

09 Streets as Social spaces


LOCAL AREA PLAN The local government has initiated Local Area Planning (LAP) for TOZ zones to densify the area, based on the principles of TOD. LAP professes to redevelop and retrofit the existing brownfield area, by a bottom up approach, with involvement of locals, stakeholders and participatory processes.

Introduction 10


SITE CONTEXT The site is located in the western fringes of Ahmedabad, an old and central residential locality- Ambawadi. It extends along the BRTS Corridor from CEPT University to Shreyas Metroline , with 200m wide buffer area on either sides. Centrally located, with proximity to major institutions and access roads, Ambawadi has become a hotspot for residential & commercial developments.

Mid rise, mixed use developments along BRT Corridor

However, currently the development around this transit corridor of Ahmedabad is not transit oriented, with low density development, stand alone institutes, lack of transit infrastructure and public open spaces.

Introduction 12


ACCESS & CONNECTIVITY The site is a well connected part of the ring of Ahmedabad, provides inter-city connectivity towards the east side of the city. It has a planned transit infrastructure, which can be further strengthened with about 13.5% of area under streets, constituting of the BRT Corridor majorly. The city transit connectivity is efficient, with coverage of most the site within 400m from the transit station.

Highly walkable perimeter: 0-300m Walkable perimeter: 300-500m

The internal roads of the site are not interconnected, owing to institutes and housing societies creating multiple dead ends resulting in less permeability, poor connectivity and large block sizes. The situation is made worse by poor condition of street infrastructure, with vendors and parking encroachment, leading to poor environment for pedestrians.

Further, the character along the BRTS differs along the corridor. Starting with institutional edge, the street character is typically defined by high compound walls, blocking the physical and visual connectivity. The footpaths along commercial buildings are encroached by parking. Introduction 14


BUILTFORM The area falls under private ownership primarily, creating an easier pitch for redevelopment. The public institutional pockets are an asset to the site, infusing a socio-cultural environment. They are also the catalysts to the surrounding developments the job centres in the form of commercial developments concentrate near major junctions and public transit stations Overall, the land use of the precinct is heterogeneous

The TOZ area is primarily characterized by residential use. It consists of detached housing, co-operative societies and a slum- the Hollywood Basti. Within these, detached housing is the most dominant housing typology, poorly consuming the benefit of the TOZ area. With an increase in population, a shift of typologies from independent housing to apartments will occur, establishing a need for redevelopment. Most of the housing stock is about 30 years old, indicating potential for redevelopment. However, some areas resist redevelopment - the slums, further impacting redevelopment in their surroundings.

BUILTFORM: Density Analysis The TOZ area underutilises FSI where the buildings are predominantly low rise when it can go upto 4 FSI, Further, a density analysis is explored which determines the achievable FSI for every plot according to the GDCR, to understand the impacts of proposed 4 FSI. Smaller plot sizes and narrow road widths (less than 12m), is the case for about 40 % of the site, which after keeping margins arent feasible for stand alone redevelopment causing due to inefficient utilization of FSI.

OPPORTUNITIES

Institutional plots are an asset to the site, giving potential to improve social infrastructure and improve connectivity.

There is a potential to create robust public realm since 70% of the area falls under roads, setbacks and vacant plots.

There is a potential for mixed use development along the BRTS corridor to create more job opportunities and positively impact public transit ridership. 25 Streets as Social spaces


CONSTRAINTS Constraints

The large institutional campuses and gated communities which restrict accessibility and connectivity with lack of spaces under public domain.

There is also a lack of public green open spaces since it constitutes only 1% of the overall site area.

STRATEGIES: BUILTFORM Identification of zones which have potential to consume 4 FSI and form high density development on the basis of the street widths, further density, transit and assets establishing varying urban character. To maintain a coherent urban character through the major transit corridor built-to-line development is proposed. For the final density distribution, the plots not able to consume 4 fsi shall transfer the development rights to the plots abutting wider roads and can go upto 70 m in height. Amalgamation of smaller plots and increase of road width is suggested to utilize benefit of FSI.

Varied typologies are recommended as Affordable housing with commercial frontages around institutions, Around major nodes podium mixed-use typology and near the metro mixed-use with arcades in the front. The final street and built character along the transit corridor will be coherent in nature with human scale inclusive residential builtform along internal streets.

Conceptual Framework 32


LAP FRAMEWORK For the overall framework, the existing site had BRT, AMTS, High tension line and institutes as primary assets affecting the redevelopment. To improve the accessibility, the large institutional blocks are made more porous and walkable through pedestrian paths, which is integrated with the larger network created by adding missing links to improve connectivity to BRT and other activity points of site, also achieving shorter block sizes. The open spaces and green cover is improved by utilising plots in public domain as parks and street plantatio. Finally, the built form that responds to these connections, with high rise dense typology along transit and nodal zones which have multiple transit stations in proximity. Built to line, high rise, podium typology along BRT corridor to create a consistent character. integrated with residential zones which will primarily have mid rise typologies. Creating a connected development by integration of assets and higher density development with improved liveability.

37 Streets as Social spaces


Shift in housing typologies, from independent bungalows to apartments, will cause an increase in population density and thus need for more open spaces.

The precinct has a low density development that is set to redevelop with availability of more FSI. Due to the development pressure around the area, imagination is that they will develop soon. This raises the concern for need of more open spaces in an already deficit area, meeting up the demands of future development.

Nehrunagar circle

URBAN CONTEXT Located at the crossroads of nehru circle, connecting Shivranjini and Shreyas Metro line, the precinct has a strong city level connectivity with major transit stations in the vicinity- the nehrunagar BRT, L colony BRT, Manekbagh BRT and the GSRTC,

Nehrunagar circle

It constitutes of housing societies- Tapovan and Manekbagh, with freehold plots, primarily low rise residential fabric. Most of the freehold plots come under the TOZ zone, eligible for an FSI of 4, while neighbouring plots an FSI of 2.7.

LANDUSE

Nehrunagar circle

The precinct has primarily residential landuse consisting of bungalows, some residential & mixeduse apartments and few commercial set ups. The outer edge is active with certain mixed use developments, with residential inside creating a homogeneous character in contrast to a TOZ zone. Most of the plot sizes fall in the range of 300 - 500 sq.m, small enough for consumption of FSI 4, indicating a need for amalgamation for future redevelopments.

TRANSFORMATION PROJECTS With the imagined redevelopment of the TOZ area, there are these two potential spaces present in the site which can be captured and designed to fufill the needs of public open spaces. The identified projects are namelyThe High Tension Line project and the Nehrunagar spine. Both of them are examples of streets being used as places, not merely vehicluar mobility. In India, streets have been the social spaces, backbone of public life. The projects draw immense poosibilities of a diverse liveable neighbourhoods.

About hundreds of kilometers of overhead High Tension lines are distributed in the city of Ahmedabad. They pass in between neighbourhoods, as no built zones. The land under which is either a vehicular street, park or barren land. These no built zones are assets to the city, where there is a crunch in public open spaces already. They have potential to serve prurposes of mobility, public greens and recreation right in midst of the city.

Shreyas Metroline

The site has a 750m wide stretch running across residential neighbourhoods from Nehru nagar circle, opening up at the BRT station, towards Shreyas Metroline. The aim is to convert the land into a pedestrian priority street connecting Nehru nagar BRT and Shreyas MRT. Urban Transformation 58


EXISTING SCENARIO Vehicular Access road for private plots

Used for parking

Private plot boundaries obstruct right of way

Shastri Park, undeveloped, used for parking

Existing Scenario

Currently, the land under HTL is used as a vehicular mobility route, parking, obstructed with several private plot boundaries and an underdeveloped park. Several plots open up towards the land, using it as a primary vehicular route. There is a need to restructure mobility in the area and transform it into a pedestrian priority stretch.

59 Streets as Social spaces

Existing Scenario

EXISTING SCENARIO 2. Amalgamation of plots to achieve higher FSI and borrow Vehicular access As smaller plots won’t have much area to develop after leaving margins, amalgamation of plots is suggested. Further, in a manner that the plot borrows access from any other road abutting other than the high tension line street.

NEHRUNAGAR SPINE PROJECT Utilising the underdeveloped leftover spaces near streets and junctions as public open spaces.

These leftover spaces are found in bulk in Ahmedabad, especially near the transit corridors, where they have the potential to get captured as a community level open space.

These islands are either filled with vehicles or are barricated with fences high enough for humans. Now is the time to tap on such land resources to squeze out open spaces.

Barren, waste of land

ABOUT SITE

Nehru nagar Circle

Parking congests the service lane at present

Length: 800 m Major Connections: Nehru Circle – Shivranjini Transit Stations : Nehru nagar BRT, Jhansi ki rani BRT, GSRTC, AMTS Bus stop

Another asset to the site is the leftover space near Nehru circle which runs parallel to the BRT corridor connecting Nehrunagar and Shivranjini.

NEHRUNAGAR SPINE as a Recreation & Transition space The space becomes a spine in rejuvenating the transit corridor along it and the neighbourhoods clinging to it. For the imagined Transit Oriented development, this place is going to get filled with hundereds of people coming in and out of transit stations between Nehru nagar and Shreyas Metroline, using the high tension street and reaching the spine. The space facilitates cross movement ensuring safety and becomes a potential public realm for future.

TRANSFORMATION Indian cities have always had a deficit of quality open spaces for people. streets are where the social lives have evolved. With most of the open spaces belonging as streets in a city, now is the time to strengthen them. Our cities have these hidden assets which need to be explored and used. Ambawadi is ready to bring in higher densities of built as well as people, with the possibility of an increase in space for public realm with a change in planning strategies and incentive model With the reclaimed streets, greens,inclusive built this place is going to transform into a lively space with people, housing, job opportunities and reduced pollution with excessive use of public transit.
